In this post, we’re going to look at why your air compressor won’t shut off and some of the best ways to fix the problem.

Read it to the end if you’re trying to fix an air compressor that won’t shut off (just runs and runs).

The air compressor does not turn off – why it happens and what to check

So your air compressor won’t shut off when it’s full?

Well, here are the possible causes and the solutions you should try:

It could be a defective pressure switch

A common culprit is a faulty air-off pressure switch (this switch is designed to shut off the compressor when it reaches the correct pressure), so this is the first thing you should check.

The good thing is that the pressure switch is fairly cheap and also easily replaced (you can buy a replacement pressure switch cheaply on Amazon).

You can usually see it if you take the cover off – the pressure switch is usually connected to the tank and is the part with some wires going into the engine.

Go to YouTube and look for videos on how to replace the air compressor pressure switch if you need help replacing the pressure switch.

Quick tip: Before you order a new pressure switch, try disassembling your device’s pressure switch and thoroughly cleaning both the diaphragm and the hose that goes back to the tank (just to make sure it’s not clogged). It could save you valuable time and money.

It’s probably a defective check valve

Also, the tank check valve may be bad and you may need to replace it.

Now, the check valve tends to loosen or wear out over time.

Once this happens, air can escape, causing your air compressor’s pump to start running constantly to make up for the loss of pressure…

What you do is open the check valve (it’s under the pressure switch)…

There could be something inside that is broken (e.g. a spring), causing a malfunction.

If the pressure switch doesn’t shut off (i.e. the check valve falsely opens), you should replace both of them.

The tank has a leak (possibly)

A leak in the tank can also cause an air compressor to run constantly.

You see, if there’s a leak somewhere in the tank, your air compressor won’t shut off because it only does so when the tank is full (and now it can’t get full because of the leak).

Therefore, examine the tank for signs of a leak and repair it.

The bottom line is, your truck air compressor won’t shut off (it really doesn’t matter what model it is) if something prevents it from reaching full pressure.

The inlet valve may be defective

It could even be a bad intake valve that is the cause of the problem.

You see, the inlet valve (also called the regulator valve because it acts as a regulator for the air that enters the unit and is compressed in the air tank) is known to wear out fairly quickly.

And when it does, your air compressor will start working for the simple reason that the pump will struggle to put in enough air to properly pressurize (and keep) the tank.

This will result in the pump not switching off.

Remember that intake valves are dirt cheap (check prices on Amazon) and very easy to replace.

You are probably looking for a faulty gauge

On some models, particularly Dewalt air compressors, a common cause of failure is a malfunctioning gauge (located on the air tank).

Now, if the gauge isn’t working properly – and this is mainly due to corrosion – the pressure is likely being read incorrectly, preventing your compressor from starting when the intended cut-out setting is reached.

Solution?

Well, you may need to install a replacement air tank gauge.

Other probable causes

Don’t forget that there are many gaskets (mechanical seals) there that could loosen or crack, causing leakage. Therefore, look for leaking seals.

Unfortunately, they’re not that easy to spot – however, a soap test should help you spot leaks (do it and see if it reveals leaky seals).

Also, there are a few other parts that keep causing the problem, including the engine failing (the engine itself may be dead!).

Also, the performance of your air compressor can be affected by dirt and grime that has gradually built up inside during normal use.

As a result, pump performance suffers and it can start to keep running.

Your first step here is to replace the air filters – and you should do this regularly to avoid problems.

The last thing you need to know is that your air compressor may be underpowered because you’re using the wrong extension cord.

Our recommendation is to switch to a sufficiently powerful extension cord (or plug it in directly).

It’s worth noting that most manufacturers specifically advise against using extension cords with air compressors.

last words

A faulty pressure switch, a faulty check valve, and leaks are the most common causes of an air compressor not shutting off.

Other things worth checking are the gauge and intake valve.

Also keep in mind that even the engine could have problems, so check it out as well.

If the above doesn’t fix the problem, you may need to consider listing your air compressor for sale on Craiglist (or other second hand sites) and hope you find someone to buy it. Otherwise you could end up losing a lot of cash.

Air compressors are powerful and indispensable machines that simplify a wide range of complex tasks. Proven in both commercial and industrial settings, these high-performance devices are must-haves for facilities looking to improve day-to-day operations. Air compressors are also versatile and flexible as they come in different types for different uses. They make the working environment safe, clean and comfortable.

Like many intensively used machines, air compressors require regular maintenance to maintain their efficiency and effectiveness. However, they are prone to wear and tear under heavy use. You will eventually run into problems. Luckily, it doesn’t have to be expensive. The first step is to identify the problem you are dealing with and know how to fix it.

Common Air Compressor Problems

Keep an eye on these air compressor problems and know the solutions you can perform should they arise:

1. Compressor failure

An air compressor that won’t start is one of the most basic problems you can encounter when operating the machine. It can result from a simple oversight. If your compressor will not start, shut down, or deliver air pressure during operation, it could be due to one of the following issues:

Compressor does not start

This is often due to missing power connections, e.g. B. a disconnected power cord or a disabled power switch. Before starting, just check the power button and switch. If necessary, breakers should also be checked.

Aside from a lack of electrical power, air compressors can also fail when there is insufficient air pressure relative to the cut-in pressure. In this case, check the cut-in pressure settings and adjust accordingly.

It could also be due to lack of oil. It is important to check or change the compressor fluids to prevent the tank from running dry.

Compressor does not stop

The compressor should stop working once the tank pressure reaches the cut-off point. If this doesn’t happen, it could be either a faulty pressure relief valve or a faulty power switch.

If the valve unsuccessfully releases pressure, the compressor will be pressurized too much to stop working and this could seriously damage your machine. In this case, cut off the power supply and replace the valve. On the other hand, a defective power switch cannot give a shutdown signal to internal controls. A new switch should solve the problem.

Sufficient pressure is not provided

If the compressor is active but not producing air pressure, there may be a problem with your air intake pump. Or it could be a problem with your seal between the compressor’s low-pressure and high-pressure chambers. Replacing them will allow your machine to perform better.

2. Stuck problems

If your compressor only works efficiently for a short time and quickly runs out of air, often prematurely, there may be an engine problem.

Compressors can also stall if they share power with other machines. Air compressors require their own power supply going to a 15 to 20 amp circuit breaker.

Another culprit could be your relief valve. To diagnose the problem, open the tank to drain the water and bleed the air. Close it and then turn it back on. If the air compressor is still stuck, it’s time to change the valve.

If the problem persists after making the necessary changes, your machine may not be able to handle the demands of its current applications.

3. Air leaks

If you turn off the air compressor once the tank is full and find that the pressure gauge reads a lower pressure, you have an air leak. Fortunately, leaks can be easily sealed. To locate the source of the leak, try listening for a hissing sound or run your fingers over the component to feel air escaping.

If you can’t find the leak this way, smear the connectors, including the couplers and power button, with liquid soap. Bubbling will show you the location of the leak. Tighten the coupling where it is blistering to seal.

You can also check the tank check valve. Air leaks usually occur when the valve does not fully close. If the gauge continues to drop when the tank is shut off, check the condition of the valve and clean or replace if necessary.

4. Pressure and flow problems

Pressure and flow issues are more subtle. The machine still appears to be working properly. Air compressors can either build up too much air or no air at all. Likewise, the pressure can only go up to a certain PSI and not much further. If you notice these problems, components such as the intake valve, discharge valve, gasket, piston seal, or tank check valve may be affected. Inspect these components and replace them if worn or damaged.

Pressure and flow problems can also be due to:

Clogged intake filters that stress the compressor and cause it to take longer to build up air

Poorly fitting coupling blocking airflow

Pressure gauge set to low

5. Uncharacteristic noise and vibration

Loud noises or unusual vibrations coming from the air compressor can alert you to problems. These signal an internal fault. While this inevitably means significant repairs are needed, small adjustments can prevent worse problems.

The noise and vibration can be caused by:

Loose Parts – Tighten or adjust loose or misaligned screws, belts, or pulleys.

– Tighten or adjust loose or misaligned screws, belts, or pulleys. Defective Crankcase – Inspect the crankcase for defects or insufficient oil level. Determine if it needs new bearings, more oil, or if it needs to be replaced entirely.

– Check the crankcase for defects or if the oil level is too low. Determine if it needs new bearings, more oil, or if it needs to be replaced entirely. Problem Pistons – Pistons hitting the valve plate can be noisy. Adjust them accordingly.

– Pistons hitting the valve plate can cause noise. Adjust them accordingly. Improper Mounting – A compressor that is not held securely on its mount may move noisily when in use. Retighten the bolts or install anti-vibration mounts if necessary.

6. Oil problems

Oil consumption problems can seriously damage your compressor. The most common oil problems include:

Oil Drains Quickly – When oil doesn’t last long, it can be due to factors such as intake clogging, oil leaks, worn piston rings, and improper oil viscosity.

– If the oil does not last long, it can be due to factors such as intake clogging, oil leaks, worn piston rings and incorrect oil viscosity. Sprayed Oil – Oil can contaminate and damage machine parts. Escaping oil can cause seals to crack or swell and plastic areas to become brittle. Causes include a clogged air intake, expired or reversed piston rings, too much oil in the tank, and improper oil viscosity.

7. Extremely hot emissions

If the compressor discharges air that is too hot, it may damage objects or surfaces it comes in contact with. The internal mechanisms of the compressor can also be compromised.

Extreme air heating can be caused by:

Dirt has accumulated in the compressor.

The compressor is placed in a hot or poorly ventilated place.

Worn head gasket and valves.

The compressor has a restricted air intake.

Depending on the cause, you may need to replace parts or relocate your compressor.

Compressed air is one of the most important components in the production process throughout industry. In both car assembly plants and newspaper press plants, rotary screw compressors serve various applications along the assembly line. Consequently, air compressors are heavily used and require consistent maintenance. Even a well-maintained air compressor can have problems with its various components, any of which could be symptomatic of a larger problem.

Unfortunately, many compressor operators ignore these warning signs, in part because they are unfamiliar with the telltale symptoms. Therefore, it is important to have an air compressor troubleshooting guide on hand to know how to fix specific symptoms, as well as a list of actions to take for each problem.

The functions of a screw compressor are relatively simple. A pair of turning screws introduce air into the chamber, which tightens the chamber and causes air pressure to increase in inverse proportion to volume. Control functions set the pressure range according to the needs of an application.

Despite this simple process, the design of these compressors consists of complex parts that can get into trouble in a multitude of ways. If these problems persist without maintenance, a minor problem can escalate into a costly system failure, ultimately requiring parts to be replaced. Therefore, it is important to know the sounds and visual cues of a failed compressor.

The main reasons for the failure of air compressors

A variety of problems can cause a rotary screw compressor to fail well before its full life expectancy. Problems like air leaks, clogged filters, and insufficient lubrication can all serve as warning signs of a system beginning to fail.

While you should always carry out compressor maintenance on a scheduled basis, the problems associated with system failures can still take root if certain problems and their symptoms are not recognized. The following issues are the main issues to look for as you continue to troubleshoot your air compressor.

air leaks

Leaks along a system are often the cause of an air compressor failure. These leaks can occur as parts wear out over time. If cracks form along any of the pipes or hoses, the air loss can be a slow but gradual process. Gradually, the crack will make your system far less efficient.

When a leak gets big, it can become an audible problem that isn’t too difficult to track down if you follow the noise. However, in many cases, ultrasound equipment is required to isolate the source of the problem. In either case, air leaks can be a costly problem due to the lost productivity that results from reduced amounts of compressed air in a given set of operations.

Pressure limits exceeded

Compressor failures are also often the result of overpressure. When plant operators operate compressors at pressure levels in excess of the recommended limits, the plant components are unduly stressed by the effect of this overpressure. Basically, air compressors have limitations for a reason.

Pressure limits can be exceeded when a single air compressor performs too many simultaneous operations. If you’re using a small machine to handle a variety of heavy-duty tasks, you’re likely shortening the life of the air compressor. While it may seem like you’re saving money by overloading an air compressor, you can actually save in the long run by investing in a second compressor and balancing the workload.

The costs associated with overpressure can be financially draining in a number of ways, as overpressure leads to wasteful energy consumption, reduced service intervals, more frequent downtime and earlier compressor failures.

Clogged air filters

The air filters are among the most important components of a compressed air system. Without the air filters, the compressed air produced by your system would become contaminated with dust and debris en route to each endpoint application. However, air filters themselves get dirty and need to be monitored frequently.

When dirt and dust build up on the air filters, contaminants move through the system and degrade the quality of the compressed air. In addition, dirty air filters degrade system performance, forcing the system to expend more energy just to perform basic functions. If the problem persists, dirty air filters can lead to excessive energy consumption, costly maintenance and downtime. Screw compressor overheating is also sometimes the result of clogged air filters.

Rare maintenance

Another oversight that can lead to premature compressor failure is poor maintenance. If you haven’t established a maintenance schedule for your air compressor and its various attachments, problems can easily arise and spread before you even realize it. In some cases, the problems can stem from simple issues that you can fix in minutes during a routine checkup.

For example, you can counteract contamination and the gradual wear and tear of plant resources with daily inspections of filters and valves. At times when nobody is using the system, turn off the compressor and close it on the valves. In addition, you should monitor the system noise regularly to ensure that there are no erratic patterns. It is good practice to set a day of the week or month for each area of ​​system maintenance.

Insufficient lubrication

As with automobiles, air compressors must be adequately oiled and lubricated to function as intended. Some of the most common causes of compressor failure are irregular oil changes and neglected greasing intervals. If you don’t adequately lubricate the internal components of an air compressor, friction will occur between the metal surfaces.

As the lubrication ages, it loses its viscosity due to prolonged exposure to heating and cooling cycles. If the work environment becomes excessively humid, grease can liquify and lose its ability to properly lubricate moving parts. Likewise, the lubricant can become icy and ineffective when extremely cold temperatures permeate the work area. Alternatively, if you age a lubricant beyond its useful life, its properties can become acidic and have a varnishing, corrosive effect on internal parts.

When replacing the oil and lubrication in your air compressor, it is important to remove the old oil. When old and new oils mix, the former can affect the quality of the latter. For example, if you refill a dirty oil tank, the acid from the older oil lining the interior can damage the new oil supply and reduce its freshness. The problems associated with waste oil will soon resurface. A similar effect can occur when you apply fresh lubricant to old, hardened lubricant.

Dirty air/oil separator

For compressed air to be clean and pure at the end point, oil must be filtered out of the system before the air leaves the machine and flows through the hoses. Oily compressed air can seriously affect the quality of pneumatic operations such as sanding, spray painting and air drying.

The component that prevents compressed air from becoming saturated with oil mist is the air-oil separator, which removes oil from the air before it leaves the compressor. However, the air/oil separator can only hold a limited amount of oil deposits, which can eventually spread to adjacent parts and have an adverse effect on the overall system. Therefore you must replace the air/oil separator regularly, preferably after 800 hours of operation.

A faulty Airend

The screw component of a rotary compressor – alternatively called the pump or airend – is the main element of the system functionality. However, the pump can wear out and require maintenance long before it reaches the end of its life expectancy. Therefore, troubleshooting of screw compressors is often required in this area.

Problems that can cause pump failure include overheating and excessive system pressure. If condensation continues to form inside the unit, the effects of humidity can damage the airend. The influence of vibrations and the effects of oily residues can also stress the screw component. When the air compressor appears to be lagging, stuck, or defective, this area is often the root of the problem. Signs of an advanced problem include oil seal leaks and strange bearing noises.

drive train problems

On belt driven models, the belts and pulleys should be checked every 500 hours of operation. Models with the direct coupled rotary screw will need to be aligned if the motor and airend are misaligned. If misaligned, motor and compressor bearings can wear out and lead to compressor failure. To ensure proper alignment, it is generally best to consult an air compressor service professional.

Improperly lubricated engine bearings

The bearings in the compressor motor ensure the operation of the system. Adequate amounts of grease applied regularly will help the bearings move smoothly. If the amount of grease is insufficient, the bearings can cause friction with each other and degrade the overall performance of the motor.

To keep the engine bearings in good condition, you must lubricate them with the correct grade and viscosity of lubricant. Failure to do so may result in system overheating, excessive power consumption, and premature system failure. Do not mix or alternate motor grease types on bearings as the properties of each lubricant may conflict and be corrosive.

How to prevent screw compressor failure

The easiest way to fix air compressor problems is to catch them early. Nonetheless, you can fix even the more advanced problems if you follow a turning screw troubleshooting guide and service or replace the affected parts.

However, you should read any symptom related to air compressor failure as a warning sign to shut down the system and service it immediately. Not acting now could ultimately prove to be a costly mistake. Therefore, you should have an air compressor troubleshooting chart available with a list of actions to take for each of the following symptoms before failure.

Air compressor does not start

If you press the power button and the compressor doesn’t activate, the problem is usually an electrical issue. In some cases the machine has triggered via a safety device. In any case, you should first check for the following errors:

Separate power supply

error on the display

Failed emergency stop

Check the overload relay and reset if necessary. There could be a problem with the phase sequence if the installation was new. In any case, it’s always best to check for simple problems before considering the possibility of more serious problems.

Compressor switches off at high temperatures

If your compressor shuts down abruptly when it reaches a certain temperature, the problem is likely due to one of the following:

Excessive ambient temperature

Poorly ventilated workplace

Wrong type of oil

Dirty oil cooler

Defective thermostatic valve

Clogged/dirty oil lines

The most common cause of compressor burnout is overheating, which can occur when too much moist air is trapped in the work area, especially on compressors with clogged vents. If the machine is against a wall and the vents don’t have room to breathe, consider moving the compressor to a more ventilated location. Also check the oil and clean the radiator and oil lines if necessary. When oil corrodes and loses its proper viscosity, internal machine parts begin to grind, causing friction and overheating.

Compressor runs but not charging

Screw compressors operate in two load modes – the loaded or “pump air” mode and the unloaded or “idle” mode. The inlet valve, through which air loads pass, opens or closes depending on the air requirement. The solenoid valve supplies controlled air to the same valve. If the compressor is not loading, check the following:

The power source of the solenoid valve

The coil of the solenoid valve

The performance of the solenoid valve

The performance of the intake valve

Make sure the solenoid valve has power and that both the solenoid valve and the intake valves are working free of obstructions.

Insufficient pressure

If your air compressor is producing air pressure at low power, check the current air demand. In some cases, the requirements of different tools are too small to justify normal pressure levels. Also check for the possibility of a leak anywhere along the compressed air system. If you really do not have enough air pressure for your current betting round, follow these steps:

Check the inlet valve for clogs.

Check the inlet filter for dust or dirt.

Check the condition of the air filters.

Check the oil separator.

Replace the air filters and oil separator if necessary. Clean the inlet filter as needed and make sure the valve is fully open.

Safety valve fails

If the compressor does not unload, check the pressure switch to make sure it is working properly when set correctly. Also check the performance of the intake and solenoid valves. If the oil separator is behind the safety valve, check its differential pressure.

Compressed air saturated with oil

If traces of oil pass through the separator, it can affect the quality of your endpoint applications. When oil saturates the compressed air, the problem is usually one of the following:

A used, dirty oil separator

A clogged flush line

Operating temperature is too high

Oil level is too high

The type of oil is unsuitable for the compressor

The minimum pressure valve is defective

If the oil separator is old and dirty, replace it with a new one. If the oil is diluted, change to a more appropriate brand with the correct viscosity.

moisture in compressed air

Water particles make up part of all ambient and compressed air. Therefore, there is no way to guarantee compressed air without moisture content. However, a well-functioning compressor should keep water content to a minimum.

If the water content increases at the expense of the endpoint functions, check the condensate trap. Does it seem to trap water at normal levels? Water should come out every few minutes. If you use the manual drain, little or no water should come out. If your system includes an air dryer, make sure the dew point is ideal.

Failure of the overload relay

If the overload relay trips, check the current draw and clamp meter on your air compressor. If the motor is drawing too much current, follow these steps:

Physically turn on the compressor, but only when it’s off.

Check the insulation of the motor windings.

Check the operating voltage of the compressor.

Make sure you can turn the compressor without making hiccups. If the voltage drops every time the compressor is turned on, the connection is weak. If the compressor still trips due to overload despite normal amperage, replace the overload relay.

Air compressors are used for all types of work. They are used for a variety of different industrial applications and smaller compressors are commonly found in private garages and workshops around the world. And as with anything else, proper care is essential to keep the compressor performing well and operating safely. And an important safety issue that air compressor owners must be aware of is the possibility of an air compressor explosion.

Air compressors can explode under certain conditions. The most common cause of air compressor explosions is excessive corrosion in the tank. If corrosion compromises the integrity of the tank, the pressure of the compressed air can cause the tank to rupture or explode.

Read on to learn what else can cause an air compressor to explode and how to prevent this safety hazard from happening to you.

What can cause an air compressor to explode?

There are a number of possible factors that can cause an air compressor to explode. Compressor explosions are rare but possible, so it’s important to consider these factors. These include:

corrosion (rust)

heat

overpressure

Faulty valves

manufacturer error

puncture

lubrication problems

Corrosion/Rust

As mentioned above, rust is the most common cause of explosions in air compressors. It’s not quick. It takes time because what happens when water sits in the tank long enough to cause excessive corrosion that can damage the structural integrity of the tank. And a tank that is structurally defective can eventually succumb to the immense pressure of compressed air, which can cause an explosion.

All air contains some amount of water, so preventing water from getting into an air compressor is impossible. However, you can take measures to ensure that water does not cause corrosion and thus prevent a rust explosion. We will cover these steps later in this article.

heat

Overheating of a compressor can also cause an explosion, although mechanical failure is more likely. Every compressor has a recommended operating temperature range and exceeding this range can result in an explosion.

For larger industrial compressors, the refrigeration system is essential and requires regular maintenance to prevent the compressor from overheating and exploding.

Too much pressure

Exceeding the maximum pressure guidelines on a compressor can cause an explosion in a number of ways. If the tank is weakened by corrosion, too much pressure can make an explosion more likely. Or if a pressure relief valve isn’t working, the excessive pressure can cause the tank to rupture.

manufacturer error

Manufacturing defects that have such drastic consequences as an explosion are rare. When they happen, they’re usually a little more harmless. However, it is always possible for a compressor to be manufactured with defects such as defective valves that could potentially cause an explosion.

puncture

Since compressors are often used near heavy machinery, there is a risk of breakdowns from falling equipment, debris or dropped tools. Although compressor tanks are designed to withstand high pressure, it is best to take steps to protect the compressor from flying debris or other things that could potentially damage the compressor and cause an explosion.

lubrication problems

Proper lubrication is essential for the safe operation of the compressor. If the device is not properly lubricated, friction in the moving parts and an explosion can occur.

How to prevent an air compressor explosion

Preventing an air compressor explosion is all about following the right guidelines and generally taking proper care of the equipment. Since corrosion is the number one cause of compressor explosions, let’s start there.

Be sure to drain your compressor regularly. This is best done daily if you use the compressor every day. Drain the compressor at least once a week. This will prevent too much water from accumulating in the tank and causing corrosion.

Do not exceed the compressor’s recommended temperature guidelines.

Do not exceed the compressor’s maximum recommended pressure.

If components appear faulty or do not fit as intended, do not use the compressor and contact the manufacturer.

Take precautions to prevent accidental puncture by other devices.

Ensure proper lubrication by regularly checking the oil level and adding oil as necessary.

Can an air compressor explode from excessive heat?

When we talk about heat and air compressors we are talking about ambient heat e.g. B. where the compressor is stored and overheating of the compressor.

In general, you don’t have to worry about ambient heat with an air compressor, although if you live in a particularly warm place, proper lubrication is a little more important as your compressor is likely to be operating at a higher temperature. The optimal operating temperature is between 50 and 90 degrees Fahrenheit.

It’s possible for an overheated air compressor to cause an explosion, and this is where you should be concerned about excessive heat. This is usually caused by poor lubrication, which causes friction and can force oil into the valves. And this oil can ignite and cause an explosion or rupture.

This will ensure your air compressor is safe to use

Everything you need to know to ensure your compressor is safe to use is in your owner’s manual. If you follow the instructions there, you will get the details for proper maintenance and safe use. However, for some general guidelines, follow the steps below to ensure your compressor is safe to use.

Drain the air tank regularly – once a day or at least once a week. This valve is located slightly at the bottom of the tank somewhere.

— once a day or at least once a week. This valve is located slightly at the bottom of the tank somewhere. Change the oil once a year. This is easier than you think and will help ensure proper lubrication. In the meantime, check the oil level regularly.

This is easier than you think and will help ensure proper lubrication. In the meantime, check the oil level regularly. Change the air filter once a year. You can usually do this by hand or with a quick use of a screwdriver.

These basics, along with recommendations from your owner’s manual, can help ensure you have a properly working air compressor.

Is It Safe to Leave an Air Compressor Pressurized?

Leaving an air compressor pressurized can be safe or dangerous depending on how well the compressor is maintained. If you use the air compressor within a few hours, you can leave it under pressure. If not, you should bleed the air from the system.

The fact of the matter is that if you pressurize your air compressor for too long without deflating it, you are allowing accumulated water to corrode the metal in the tank. And while depressurizing the tank doesn’t automatically drain accumulated water, these steps are best done simultaneously.

Making a habit of depressurizing the tank and immediately draining moisture can ensure long compressor life and safe operation for you and all other users.

Are Air Compressors Safe to Use?

With all this talk about exploding air compressors, you might be wondering if they are safe to use. While air compressors can explode, this is a fairly rare occurrence. Provided you use common sense and follow the manufacturer’s maintenance tactics, air compressors are safe to use.

Like any tool, a compressor can be misused or poorly maintained, which can increase the risk of injury. If you are using a compressor in your own garage or workshop, take the time to read the owner’s manual and follow the best practices within. This ensures safe operation of the compressor.

If you work with compressors in a commercial setting, your business should have professionals who regularly service the compressor to ensure it is working safely.

Conclusion

It takes a lot to detonate an air compressor. The most common cause of these breaks is corrosion, which occurs from the inside out. Fortunately, this is easily prevented by regularly draining moisture from the air compressor tank.

Other factors can contribute to air compressor explosions, but they are rare. The best thing you can do to prevent an air compressor explosion is to read your compressor manual and follow the best practices outlined there.

It can be difficult to find a reset button on an air conditioner, especially when it happens so infrequently that it’s difficult to remember! If you recently had a power outage, e.g. B. a brownout, turn on a light to make sure you have full power before restarting your device.

This is a crucial step before restarting your air conditioner. You won’t know if the air conditioner needs to be reset if it’s not at full power to begin with. It is also important to understand if your Suwanee HVAC system needs to be reset or the air conditioning needs to be replaced.

Why should you reset your air conditioner?

You recently had a power outage

These power interruptions, whether power outages or brownouts, can cause cooling issues for your device until it is reset.

The thermostat in your house is not working properly

Sometimes it’s due to a faulty thermostat, no matter how many times you reset your air conditioner. It’s not hard work and I’m sure you could finish it in an hour or two.

A reset button is located in the air conditioner compressor. Typically, the button is red in color and modest in size.

Step-by-step instructions on how to turn off the air conditioner using the reset button

1. First you need to find the reset button. You can find them on almost every unit. It is usually small and bright red. If you can’t find it, check your air conditioner manual to find out where the button is.

2. Unplug your device for at least 15 seconds before plugging it back in.

3. Then press and hold the reset button for three seconds before releasing it. If the device does not turn on, repeat the process.

4. If it doesn’t work, find your fuse box and try turning on the one connected to the air conditioner. At this point, your device is probably on.

How to manually reset the system without the reset button

1. First, locate the power switch near your external compressor unit and turn it off.

2. The 240 volt circuit needs to be arranged next. This can be found in the main electrical panel of your home. Turn off the power to this circuit.

3. Only disconnect your device from the power supply board to ensure that it is completely de-energized.

4. Leave the device unplugged and turned off for at least 20-30 minutes to allow the charge to dissipate.

5. After waiting, make sure your device is set to cool and plug it back in.

6. Reconnect the 240 volt circuit and the power cut-off near the compressor outside. Because you’re working backwards from the first power off, it’s important to follow this order.

Compressors are often diagnosed as defective due to an open thermal overload. The purpose of the overload is to shut down the compressor when it gets extremely hot.

Imagine the following scenario: A technician is called because there is no cooling in the house. The technician finds that the compressor is not running. He checks the continuity between the wires with a multimeter and finds an open between R&C and S&C. It is rare for both the R (Run) and S (Start) windings to be bad. The technician runs a few other checks, one of which is continuity between R&S. The reading is 2 ohms. This means that the R and S windings are not open as first suspected. Why could this be the case?

If you look at a compressor’s wiring diagram, you will see that there is a thermal overload in the common circuit. When the overload opens, you get no continuity between the common terminal and the R or S terminals.

During the continuity check, the technician found that the compressor was hot. You need to let the compressor cool down, so unplug the power and wait until the next day (or hose it down if you’re in a hurry) to check the compressor’s windings again. This time the compressor outputs correctly. Now the technician needs to determine why the compressor is overheating.

An overload can be opened for the following reasons:

A lack of maintenance. If the outer coil becomes dirty, it can increase head pressure and cause the device to run hot.

A defective run or start capacitor. These two points need to be checked.

Insufficient voltage, especially on 3 phases.

lack of refrigerant. Refrigerant helps cool the compressor windings.

Do your due diligence to find out why the compressor is overheating and you will not misdiagnose the problem and replace a perfectly good unit.

air leaks

Good air pressure is essential for a powerful machine. If air leaks from your tank or hoses, you will notice low pressure, which means additional time and energy costs that can leave your business behind. An air leak can be due to one of several factors. Luckily, leaks can be sealed with the right kind of air compressor troubleshooting. The following symptoms are among the most common leak-related air compressor problems:

1. Compressor keeps leaking

If you turn off the air compressor on a full charge, but the gauge drops while the compressor is disabled, you definitely have an air leak. The compressor might even restart automatically just to counteract the situation. What you need to do in this situation is locate the source of the leak.

Apply soap to fittings: With the compressor unplugged, cover the fittings with liquid soap, including all couplings and the pressure switch. If bubbles form anywhere, that’s where the leak is. If possible, tighten the clutch where the blistering occurs.

With the compressor disconnected, cover the fittings with liquid soap, including all couplings and the pressure switch. If bubbles form anywhere, that’s where the leak is. If possible, tighten the clutch where the blistering occurs. Check the tank check valve: Air leaks are sometimes caused by tank check valves not closing completely. If the pressure gauge continues to drop with the tank off, access the tank valve and check its condition. The valve may need to be cleaned or replaced.

If the air leaks only occur when a hose is connected to the compressor, disconnect the hose. If the pressure gauge stops dropping, the hose is the source of your leak.

2. Air leaks from the oil filler tube

If your compressor is losing pressure through the oil filler tube, check the piston seals. In most cases, the piston seals are badly worn and need to be replaced immediately. This is an issue that you should address immediately, as worn pistons can experience metal-to-metal friction that can quickly lead to internal corrosion.

3. Air leaks from the hood

Air leaks under the hood sometimes occur with smaller air compressors. To diagnose the problem, remove the hood, run the compressor for a few minutes, then turn it off and unplug the compressor. Feel for air drafts around engine parts. The leak is probably coming from the tank valve, in which case you will need to remove the valve and clean it or possibly replace it.

Electric motor and power supply problems

If you notice an electrical problem, you need to look at it or have a professional come in as soon as possible. It could be anything from your engine capacitors to misfiring piston rings. If your air compressor loses power – or the power supply is inadequate and unreliable – the problem is most likely due to one of the following factors:

1. Compressor blows fuses and circuit breakers

Assuming your compressor is plugged into a working outlet and turned on, the following problems can cause fuses to blow:

Extension cords: If your compressor is plugged into an outlet using an extension cord, sufficient energy can be drawn from the motor, which can cause the motor to overheat. Compressors are not home electronics that can suffice on extension cords and power strips. An air compressor should only be operated from a direct connection to a power source.

If your compressor is plugged into an outlet using an extension cord, sufficient energy can be drawn from the motor, which can cause the motor to overheat. Compressors are not home electronics that can suffice on extension cords and power strips. An air compressor should only be operated from a direct connection to a power source. An old engine: If your compressor has been running on the same engine for many years, it might be time for a replacement. An older motor can have worn windings, loose capacitor wires, and other general wear and tear that can easily lead to blown fuses and breakers.

If the tank seems to drag at high pressure, there is likely a problem with the motor capacitor.

2. Dimmed compressor lights at startup

An air compressor uses enormous amounts of energy at the time of starting. This is known as the inrush current, which far exceeds the amount of current generally consumed during the remainder of the usage cycle. To prevent fuses from blowing during this inrush current, compressor motors are fitted with starting capacitors that manage the incoming power. A fading light is one of the telltale signs that the starter capacitor is worn out and needs replacing.

3. Switch trips at start

If your air compressor shuts off when you turn it on, the problem is likely being caused by trapped air above the piston. To test this problem, turn off the tank, unplug it from the power supply, and bleed all air from the tank. This should relieve the pistons of excess air pressure and allow the tank to start without further problems. Trapped air above the pistons is usually caused by a faulty relief valve which should be checked, cleaned and possibly replaced if the problem persists.

Won’t start or stop

If an air compressor will not start, shut off, or not supply air pressure during operation, the problem may be due to one of several issues. Each case should be taken separately, as follows:

1. Compressor does not start

Aside from the obvious oversights like an unplugged power cord or a disabled power switch, a compressor will typically not start if it doesn’t have enough air pressure available to it. If the cut-in pressure is not proportional to the air pressure stored in the tank, the compressor will often not start. Check the cut-in setting on the pressure switch and adjust the level accordingly.

2. Compressor does not stop

The compressor should stop as soon as the tank pressure falls to the cut-off point. If this doesn’t happen, the problem is generally one of two issues:

Defective pressure release valve: If the valve does not release the pressure, the tank is too pressurized and the engine will no longer run. In such cases, you should disconnect the power supply and stop using the compressor until the valve is replaced, as continued use could seriously damage the compressor.

If the valve does not release the pressure, the tank is too pressurized and the engine will not run. In such cases, you should disconnect the power supply and stop using the compressor until the valve is replaced, as continued use could seriously damage the compressor. Faulty pressure switch: If the pressure switch is not signaling the internal controls, a new switch should solve the problem.

Pressurization components are at the heart of a compressor’s functions and when they fail, the compressor essentially fails.

3. Compressor runs but does not produce air pressure

If the compressor runs and runs but there is no air pressure, the problem is likely due to one of two issues:

Faulty Pump: If the engine runs and makes noise but no air is coming out, you likely have a faulty air intake pump that needs to be replaced. As long as the compressor is not too hot, you can manually feel the lack of pump pressure with a pair of protective gloves.

If the engine runs and makes noise but no air comes out, you probably have a faulty air intake pump that needs to be replaced. As long as the compressor is not too hot, you can manually feel the lack of pump pressure with a pair of protective gloves. Defective seal: If the compressor only produces low pressure, there may be a problem with the seal between the low-pressure and high-pressure chambers of the compressor, e.g. B. when air flows from side to side without sufficient pressurization.

Fortunately, pumps and seals can be easily replaced. With a simple parts replacement, you should be able to get many more years of performance out of this compressor.

oil in air lines

If compressor oil gets into the air lines, the effects can be detrimental elsewhere in the compressor since the pump uses a different lubricant than other parts of the system. Once in the air lines, this oil is distributed to other areas, potentially causing seals to crack or swell. Oily air lines are most problematic when the oil gets to the plastic parts of the air valve.

The negative effects of oil on plastic are due to the additives in the oil, which can cause plastic surfaces to become brittle and eventually chip. In such circumstances, for example, a plastic grease cup could rupture if the air pressure exceeds a certain threshold. You can protect the shell – or contain the plastic in case of breakage – by securing it with a metal cover.

In a piston compressor, the oil must first get past the piston seals to the tank. In this case, the seals should be replaced immediately. This would also be a good time to replace the valve and seal.

As soon as you notice that oil has gotten into the air lines, check the oil pan to see if there is still enough oil. If the problem persists, the sump could be depleted of its oil supply.

As you remove the oil, take a look and make sure it appears clear and consistent. Sometimes you may notice that your oil looks milky – this happens when your air compressor has been exposed to excessive moisture and condensation has gotten into the oil reservoir. In this case you should drain and replace the oil and move your air intake pipe to a less humid environment.

pressure and flow problems

Some of the most common air compressor problems involve pressure and flow issues, which often manifest themselves in the following symptoms:

1. Clogged inlet filter media element

The main reason for replacing an intake filter is when it is corroded or damaged. However, the filter could be the source of pressure and flow problems if the inlet is clogged. Telltale signs of trouble include the following symptoms:

The compressor tank takes longer and longer to build up air pressure.

The motor keeps overheating and trips the thermal protector.

If these problems occur, remove the filter housing from the suction pump and run the compressor again. If the problems stop and the compressor runs normally, the problem is in the air intake medium. From here you have two options – Clean or Replace. To clean a compressor filter, run water through it until you can no longer see dirt particles.

You can replace the media with various types of filter elements that are available at specialty stores and auto parts stores. The best options are media similar to those used in air conditioners. Cut the media to the dimensions of the suction filter and swap the old ones for the new ones.

2. No air from the hose

If an air hose is connected to your compressor but no air is coming out, the problem could be due to one of several factors:

The tank lacks air. This would be indicated by a zero pressure reading on the tank gauge.

The regulator pressure is set to zero. If this is the case, adjust the regulator to within 20 psi of the compressor’s cut-out pressure.

The outlet coupler is equipped with the wrong hose connection, which will block the airflow. This could be the case if you recently replaced one of the parts without checking the OEM specs.

The problem could also be due to the simple fact that the connection on the attached pneumatic tool is poorly suited to the clutch.

3. Air comes in short bursts

If your tank has adequate air volume but produces very little air pressure, check the pressure gauge readings. If the gauge is too low, you are not getting adequate air pressure from the tank. If your fuel gauge is 100psi, the gauge should be adjusted to around 90psi.

Parts and repair required

When an air compressor stops working because of a defective part, you must first test the part to determine the source of the problem. A compressor will not work if the following parts are defective. Fortunately, all can be replaced:

1. Cracked inlet filter

The intake filter is a crucial part of the air compressor as it filters impure particles from the incoming air. Because it physically protrudes from the rest of the unit, an intake filter is one of the most breakable parts of an air compressor. Luckily, it’s also one of the easier parts to replace. As long as you can find a filter with the same thread size and roughly the same gantry size and diameter, it should work for your machine.

2. Defective air compressor manifold

If you break the pressure switch on an air compressor, you may be surprised at the complexity involved. The fact is that any old replacement switch will not solve the problem due to the many connection points of the distributor. To fix the problem, you need to find a switch that will accept each of the four or five connection points, which generally include sockets for the pressure relief valve, air tank gauge, compressor tank, and quick disconnect.

Before purchasing a new pressure switch and manifold, note the following details on the old switch, all of which must be matched to any new switch you are fitting to the compressor:

The number of connections on your pressure switch and manifold.

The voltage of the original pressure switch.

The on and off settings of the old pressure switch.

The connection of the relief valve.

Be sure to properly thread the fittings on the new manifold onto the appropriate parts on your air compressor.

3. Defective compressor fan

Many newer air compressors – particularly those on the less expensive end of the spectrum – blow air with fans made of plastic, which is cheaper than metal but is also more susceptible to wear and tear. Fortunately, a replacement fan made from either material will work in almost any compressor. So if you have a fan with broken plastic blades, you could turn this into an opportunity to upgrade to metal.

Before selecting a replacement fan, check the compressor manual for a listing of the part number and corresponding dimensions. If not found, measure the dimensions and hole diameter of the original fan. Note the number of blades and the direction of airflow, as both details depend on the power and make of the compressor.

4. Defective on/off switch

If your air compressor motor doesn’t turn on when you flip the switch, it could be the switch itself, although you should do some testing before jumping to any conclusions. Check the power cord to make sure it is plugged into a working outlet. If the power button still doesn’t activate the compressor, plug a light or electronic device into the outlet to see if it turns on.

If the outlet works for other devices but not your compressor, peel back the case that encloses the switch, remove it from the outlet, and check the compressor’s manual for the switch’s specifications. Make sure your replacement switch meets specifications and fits the outlet.

How Short Compressor Cycle Times Affect Your Business Monday, March 19, 2018

Two of the most important things you can do to keep your HVACR system running efficiently are regular inspections and preventative maintenance. Knowing what’s wrong with your equipment and when to inspect can mean the difference between a manageable cost and thousands of dollars in repairs. The following can help you understand how short cycling affects your business and how maintenance can help.

The basics of short cycling

Short cycles refer to your compressor shutting down prematurely due to a mechanical failure. In this case, the HVACR system will be forced to restart slowly. This requires the compressor to be kept on more frequently, increasing costs and reducing efficiency. A short cycle or two isn’t a problem, but if this problem goes undetected, it can cause problems over time. If you regularly inspect and maintain your equipment, you can spot small bugs that can quickly become serious problems.

Short cycling alone is a problem, but it is also evidence of a more serious problem. If you find that one of your compressors is experiencing a short cycle, it is important that you thoroughly inspect your equipment to identify the source of the problem. Do not rely on component replacement as the problem can still cause your new compressor to cycle short. Sometimes a replacement is necessary, but if you never fix the underlying problem, you’ll still have to deal with short wheel arches.

In addition to the repair costs, a short-cycle compressor also uses more energy. The constant shutdown and restart cycle increases energy consumption by 20 to 50 percent, which can add to your monthly bills.

Common causes of short cycling

Low refrigerant/oil mixture

With each compression, the compressor releases a small amount of oil to keep it lubricated, which mixes with the refrigerant. With short cycles, the oil-refrigerant mixture is unbalanced. The oil is kept out of the system and does not lubricate the compressor. Eventually, this problem could lead to bearing failure.

Dirty condenser and automatic high pressure reset

Another common problem that causes short cycles is dirty capacitors. Condensers are responsible for regulating the temperature and pressure that keep your compressor cool. If not kept cool, your devices can experience a high pressure reset, which can lead to a series of short cycles.

High capacitor discharge

If you keep your condenser in an enclosed area where the air is circulating, it will experience a steady increase in temperature and pressure. This could result in a complete shutdown of the HVACR system. This usually occurs when a capacitor is stored in a basement or indoor space. The reason for the condenser shutting off is that the circulated air is steadily heated through the condenser and is not discharged anywhere.

Control difference is too small

If the pressure regulator is set too tight, this can lead to short-strokes in the compressor. You can usually notice this problem when it is a normal refrigeration period and when the compressor switches to the low pressure setting. Finally, the compressor shuts off until the pressure rises again. These cycles result in longer working hours to achieve peak operating speeds and increase your energy consumption.

Missing operating time delay

You need the minimum and maximum runtimes for your system to work efficiently. However, your compressor must also be switched off for a certain period of time. Adequate time delay can prevent short cycles from occurring by preventing your system from using exhaust air that is still circulating in the system. This also allows the pressure regulator to reset itself.

Additional issues affecting your compressor

Another problem that companies face is the fact that their compressors are not conveniently located. Many place their compressors on roofs or in basements that are difficult to access. It also means short cycle issues may not be caught early enough. The same problems can arise if the compressors are on the side of the building as they are on pads. Because of these unusual locations, you need to create an inspection plan to inspect and test compressors. This ensures that your system is working efficiently.

The voltage of the original pressure switch.

The on and off settings of the old pressure switch.

The connection of the relief valve.

Be sure to properly thread the fittings on the new manifold onto the appropriate parts on your air compressor.

3. Defective compressor fan

Many newer air compressors – particularly those on the less expensive end of the spectrum – blow air with fans made of plastic, which is cheaper than metal but is also more susceptible to wear and tear. Fortunately, a replacement fan made from either material will work in almost any compressor. So if you have a fan with broken plastic blades, you could turn this into an opportunity to upgrade to metal.

Before selecting a replacement fan, check the compressor manual for a listing of the part number and corresponding dimensions. If not found, measure the dimensions and hole diameter of the original fan. Note the number of blades and the direction of airflow, as both details depend on the power and make of the compressor.

4. Defective on/off switch

If your air compressor motor doesn’t turn on when you flip the switch, it could be the switch itself, although you should do some testing before jumping to any conclusions. Check the power cord to make sure it is plugged into a working outlet. If the power button still doesn’t activate the compressor, plug a light or electronic device into the outlet to see if it turns on.

If the outlet works for other devices but not your compressor, peel back the case that encloses the switch, remove it from the outlet, and check the compressor’s manual for the switch’s specifications. Make sure your replacement switch meets specifications and fits the outlet.

Air compressors serve all sorts of purposes, both professionally and privately. From press shops and factories to repair shops and workshops, compressed air is used to assemble everything from cars and airplanes to appliances and home furnishings. Today’s compressors are designed to deliver optimal performance over many usage cycles with a sleek design.

When an air conditioner (AC) turns on and off fairly quickly without running for any length of time, this is known as short cycling. It’s fairly common, but when it happens it means something is wrong with the air conditioner. Don’t leave these events alone. They increase your energy bills, usually indicate a larger problem, and can cause permanent damage to your device, necessitating a costly replacement. Short cycling will also shorten the life of your AC. Call a professional technician and have your device checked. Any of our experts at Montgomery HVAC can diagnose and fix this problem for you. Don’t hesitate. Call us at 972-442-5171 so we can get your air conditioner back to its most efficient condition for you.

While there are many possible reasons for short cycling, here are some of the most common and what can be done to fix them.

Low Refrigerant

The coolant that flows through your system and helps absorb heat and cool the air in your home is called the refrigerant. You may know it by the brand name Freon®. If your refrigerant is low, the required compressor pressure levels will be affected. This will trigger your compressor’s low pressure control and shut down your compressor. When the pressure rises and triggers your air conditioner to restart, this is what causes the short cycle. If your refrigerant level is low, this indicates a leak as the refrigerant is circulating through the compressor rather than being burned. A low refrigerant level can also lead to frozen coils. A professional technician can find your leak and prevent further problems or damage.

location of the thermostat

Your thermostat acts as a sensor for your air conditioner, telling it when to cool your home. If the location is not optimal, e.g. B. near a window or too close to an air vent, your thermostat sends misleading information to your air conditioner. Suppose your thermostat is in direct line of airflow from a vent. This causes the thermostat to think your house is cooler than it really is, and your air conditioner to turn off thinking it has reached the desired temperature. With the cool air no longer flowing through the vent, the thermostat senses that your home is indeed still too warm and triggers your air conditioner to start it up again. This is short cycling. Make sure your thermostat is in a central location, away from direct sunlight and vents.

Dirty air filter

Dirty air filters are one of the most common and easiest to troubleshoot air conditioning problems we see here in Wylie, TX. The dirty filters restrict airflow which in turn causes so many problems including a frozen coil. This can cause your air conditioner to malfunction and short cycle. Make sure you change your filters regularly to avoid problems.

Oversized air conditioning

An air conditioner that is too big for your home will have short cycles because it cools your home too quickly while not properly dehumidifying it. So it shuts down and starts up frequently. You will also most likely find that your home has hot and cold spots and you will have higher energy bills. If your air conditioner was newly installed, speak to the technicians who installed it to see what they can do to help. Call one of our qualified technicians to perform a manual J heat load calculation to determine the right sized unit for your home.

Brief cycling causes a whole host of problems with your air conditioner. So if you notice your air conditioning is doing this, give one of our Montgomery HVAC technicians a call to assess the situation. You want your air conditioner to cool efficiently and last for years. Short cycling will change you briefly.

Absolutely! My Honda compressor died because of this……

They had to manually turn on the air conditioning on my Honda Civic sedan. Nobody ever told me to turn it on regularly in the winter when it was above freezing. One spring my air conditioning compressor died and had to be replaced. The Honda dealer tells me I should have turned it on at least once a week during the winter because if you don’t keep it running every now and then it will break. The car was only 2 years old at the time.
In my opinion Audi is smart to automatically turn on the A4 supercharger every now and then to avoid this potential problem.
