How do I reset my AC pressure switch?
On Rheem and Ruud heat pumps and air-conditioners, the reset button is usually red on located near the control panel. A simple push of the switch will reset the switch, and the operation of the air conditioner should return to normal until the pressure exceeds the rating of the switch.
Can you run AC without high pressure switch?
The AC pressure switch is the part responsible for monitoring the pressure. When there is enough pressure for the compressor to run safely, if the AC pressure switch fails, the compressor will not receive a signal to start, and therefore, you will not have a running air conditioning in your vehicle.
How do you check an AC pressure switch?
Check the pressure of the air conditioning system by attaching a low pressure gauge from a refrigerant recharge kit to the low pressure fitting, located between the accumulator and the compressor and marked with a capital “L.” According to AA1 Car, on an 80 degree day, the low pressure gauge should measure 56 psi ( …
How can I replace my a / C pressure switch?
In order to safely and efficiently replace your A/C pressure switch you need a couple of basic tools: Free repair manuals – Autozone provides free online repair manuals for certain makes and models Step 1: Locate the A/C pressure switch. The pressure switch can be mounted to A/C pressure line, compressor or accumulator/drier.
Do you need to unscrew a pressure switch?
Loose the switch with a socket or wrench, then unscrew it. Note: Typically, the A/C system does not need to be evacuated prior to removing the A/C pressure switch. This is because there is a schrader valve built into the switch mount.
Why is there a pressure switch on my AC?
AC splits into two halves, one is low pressure half and the other is high pressure and both sides are equipped with an AC pressure switch. They are very important safety devices that are built into the AC system because if the pressure is too low or too high, it can cause serious damage to the AC system.
What happens when you change the pressure on a compressor?
Incorrect pressure can damage the compressor, hoses, and other A/C system components. The A/C pressure switch is a type of device called a transducer, which changes internal resistance in response to changes in pressure.

Where are the low and high AC pressure switches located?
The low-pressure side switch is found before the AC compressor, while the high-pressure switch comes after the compressor. Most AC pressure switches are found within the engine compartment, but some manufacturers put them elsewhere. A look in your service manual will show you the appropriate location for your model.
