This is a general process, and your steps may vary, but it is standard for air compressor pressure switch repair:
- Unplug the compressor, so you don’t run the risk of shocking yourself or getting a nasty burst of pressurized air.
- Open the drain valve at the bottom of your tank to depressurize it.
- Locate the unloader valve and remove the line — typically ¼ inch — going to it.

Why is a pressure switch used in an air compressor?
The Air compressor pressure switch is an important part of electric air compressors. It helps maintain a proper level of pressure inside a compressor by turning it on and off. The pressure switch turns off the compressor when the pressure inside the air tank rises to a certain level and no more air is needed to be compressed.

Are pressure switches interchangeable?
Different furnaces may have different types of pressure switches in them. Based on the size of the unit (meaning heat output capability, not the physical dimensions), the amount of suction the pressure switch requires to work will vary.
How does an air pressure switch work?
A pressure switch is a simple electromechanical device that is triggered by pressure to turn an electrical circuit on or off. The pressure point that activates the switch is called its set point, and the pressure threshold that deactivates the switch is called the cut out point.

Use the Allen wrench to loosen the screw and adjust it until your multimeter reads as close to zero as possible. Now you can tighten the screw back up.
What is cut in and cut out pressure?
Cut-in and cut-out pressure These are simply the two pressures at which the compressor starts and stops. The compressor will stop when it reaches the cut-out pressure and will start again when the pressure drops back to the cut-in pressure. So, the cut-in pressure is always lower than the cut-out pressure.

Over time, the pressure switch wears out. If the pressure switch won’t start the pump when tank pressure drops below the cut-in pressure or won’t stop the pump when ...
How to turn on a compressor?
We offer these tips regarding power and wiring that might affect your machine’s ability to turn on: 1 Always plug your compressor directly into an outlet, never a power strip. 2 Use three-prong extension cords that are less than 25 feet long to reduce resistance. They should also be at least 10 gauge. 3 Check to see if the compressor has tripped your circuit breaker. Repeated circuit breaker issues could be a problem with the air compressor wiring, an electrical circuit of insufficient amperage, or your electrical panel. If other machinery making the same electrical demands doesn’t trip your breaker, the problem is probably with the compressor. 4 Check to see that rodents or wear and tear haven’t frayed any wiring. 5 Make sure the contact is good between the power switch and internal circuitry. Sometimes switches need tightening due to vibration, and old switches may need replacement.
