When do you shut off the air compressor?
When do you shut off the air compressor?
Your compressor pressure switch should shut the compressor off A typical pressure switch on your air compressor might be the Condor brand, similar to the one in the photo. It is the compressor pressure switch that is supposed to shut the air compressor off when the tank pressure reaches the cut out pressure level.
Why is my air conditioner not shutting off?
As the temperature on the sensor drops, a pressure change occurs at the control and the switch contacts will open and shut off the compressor. If the contacts weld or stick closed, the compressor will continue to run regardless of the temperature sensed by the bulb at the evaporator.
What happens when the unloader valve on an air compressor fails?
When the unloader valve fails, however, air will be trapped over the piston or pistons on the air compressor. That adds load to the drive train. Smaller air compressors operate with a very thin line between motor size and the power needed to drive the compressor pump.
What happens if the pressure switch does not shut down the compressor?
If the pressure switch does not shut the compressor down at the normal cut out pressure setting, when the tank pressure reaches the PRV set point, the PRV opens and vents the air. If the PRV fails, my friend, you have a real serious problem!
What does it mean when your AC doesn’t shut off?
If your AC is set on “auto” and set on “cool” and your thermostat is set on 73 (any number), and the AC has reached your desired temperature, but the AC doesn’t shut off and continues to blow air, this video may make you a happy camper. Loading…
Is there a backup for the air compressor?
The safety backup for the air compressor pressure switch is the PRV, the pressure relief valve. The air compressor can pump air pressure into the tank to a level higher than the compressor is supposed to.

What happens when you run an air compressor?
If an air compressor runs, pumps air into the air tank, the tank pressure reaches the normal cut out pressure setting level, and the compressor continues to run and the pressure continues to build, this is a real problem! Eventually the PRV will let go, and the tank pressure should vent.
