If you shut off the air compressor on full charge, yet the gauge drops while the compressor is deactivated, you definitely have an air leak. Air leaks from under the hood are sometimes encountered on smaller air compressors. Many newer air compressors – particularly those on the lower-cost end of the spectrum – blow air with fans made of plastic, which is less expensive than metal but is also more easily prone to wear and tear.
The following air compressor troubleshooting tips can help solve some of the most common problems that are known to occur with air compressors. If you shut down the compressor when the tank is filled with air and then find that the pressure gauge is showing a drop in pressure, you know that the compressor is leaking air. If you plug in the compressor, the pressure switch response to the air leak and dropping compressor pressure will be to start the compressor again.
Limit air usage to compressor capacity by using fewer or smaller tools. Air leaking from inter stage safety relief valve when compressor is pumping. Remove the compressor cylinder head and inspect for foreign matter on top of the piston, clean, add a new gasket, and reassemble the head. 4.
The check valve prevents tank air from back flowing to the pump. To test the check valve, let the air compressor fill the tank until the pump shuts off. The pull the ring on the safety valve to bleed air from the tank to reach the cut-in pressure, so the pressure switch tires to restart the motor to refill the air tank.
An air compressor failing to start is one of the most basic problems you may encounter when operating the machine. If you deactivate the air compressor once the tank is full and notice that the gauge indicates lower pressure, you have an air leak.

Check The Compressor Switch If Air Compressor Won’t Turn On. When my Campbell Hausfeld compressor stopped working, the power switch couldn’t turn on the compressor. The compressor will not start when an in-line fuse inside your air compressor is faulty. Porter-Cable Air Compressor Won’t Turn On. After using a portable PORTER-CABLE air compressor for home garage applications, the pressure switch had some faults.
This is especially important considering that the safety valve opens to relieve excess air pressure in the case that the pressure switch fails to turn off the compressor at the cut-out pressure setting. The most common reason behind a reciprocating compressor’s inability to reach sufficient pressure is a defective reed valve – which can exhaust air out from the air inlet on single stage models or, through the intercooler safety valve in the case of a defective reed valve on a two-stage piston compressor instead of passing it through the intercooler, through the second stage piston, and out through the discharge. Effective pump rings seal the air in the cylinders, prevent excess oil from passing downstream, and are critical in ensuring an air compressor’s ability to build pressure – if pump rings are worn, the pump will be unable to effectively compress air which can greatly reduce the volume of air the pump can produce.
Knowing how aggravating it is, here are some reasons your air compressor will not start, and a few of the things you need to look at in the hope that understanding them will help you get your air compressor back on track and working effectively. Depending on how much time you want to spend on this compressor George, you can pick up a low-cost 1 HP compressor for under $100 dollars these days, and you could either replace the entire power train of your existing compressor with the new one, or, use the existing compressor only as an extra tank, and fill the tanks on both air compressors from the new one. Turn off the compressor, dump all the air from the tank, close the tank drain, and start the compressor.
why is my air compressor not working Related Question:
How do you fix an air compressor that won’t start?
If the compressor won’t start with air in tank, replace the check valve. If the compressor won’t start with an empty air tank, replace the pressure switch if it isn’t activating the pump motor. Replace the pump motor if it doesn’t start when activated by the pressure switch.
Why is my air compressor not building pressure?
The most common reason behind a reciprocating compressor’s inability to reach sufficient pressure is a defective reed valve — which can exhaust air out from the air inlet on single stage models or, through the intercooler safety valve in the case of a defective reed valve on a two-stage piston compressor instead of
How do you reset an air compressor?
To reset your reciprocating air compressor, allow time for the compressor to cool down and then push the reset button before attempting to turn the unit on again.
Why did my compressor suddenly stop working?
You will want to have the unit examined to look for signs of a blown fuse, a tripped circuit breaker, a broken thermostat, or dirty air filters. Dirty or clogged filters commonly make AC compressors stop working.
Is there a fuse for the air compressor?
Blown Fuse or Tripped Breaker Some air compressors have reset switches while others will have in-line fuses that need to be checked. To find them follow the line of power from the air compressor back to the outlet. If you find a blown fuse or tripped breaker go ahead and either replace the fuse or reset the breaker.
What happens if air compressor runs out of oil?
Running a compressor out of oil can seize the engine (much like your car) or a bad bearing in an electric motor can seize it and cause a no-start issue.
Is there a reset button on AC compressor?
Most air conditioning units are equipped with a reset button. These buttons tend to be red and quite small. If you’re having a tough time finding it, consult your owner’s manual. (If you can’t find it, most are published online for quick reference).
Where is my AC reset button?
The reset for a whole house air conditioner is going to be in the outdoor unit. You will have to look for it. It will have a small button that’s probably red in color and two wires protruding from the top. The opposite end of the pressure switch will have a small copper tube connected to the systems refrigeration line.
Can you reset a motor?
Once the motor has cooled sufficiently it can be re-started, usually by pushing the popped-out reset switch back down. If the motor turns off again on re-set you should not keep running it as it may be damaged and the system may be unsafe.
Where is the compressor fuse located?
The fuse is a wire inside a glass casing, found in the disconnection box connected to your AC. The fuse is a protective measure meant to protect your air conditioner from electrical damage.
Can air compressors be fixed?
Air compressor repair can be simple. The air compressor unloader valve is what makes the “psssssst” sound when the motor shuts off after reaching operating pressure. It’s actually venting the residual pressure from the compressor head so the motor doesn’t have to work as hard on the next startup.
