Where is the AC high-pressure switch located?
Your AC pressure switches are located on both the high and low sides of the unit. These switches monitor and check the pressure of the refrigerant on both sides of the system, with separate switches for both the high side and the low side, which both serve to prevent pressure issues causing damage to the compressor.
How do you reset an AC high-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.
How do I test my 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 many AC pressure switches are there?
In every vehicle, there are two pressure switches, one on the high-pressure side, and one on the low-pressure side. Both switches are important in protecting the compressor from being damaged. If the compressor is running on low pressure, the compressor will get damaged because it is running on low oil.

Is a pressure switch normally closed?
Electronic pressure switches, and also mechanical pressure switches with gold contacts, are nowadays usually monitored by a PLC or central control system. “Normally open” and “normally closed” cover well over 95 % of all pressure switch applications, whereas “change-over” is primarily used for specific applications.
Are high pressure switches normally open?
Pressure switches (for example, a “normally open contact”), are often used for the monitoring and control of safety functions in order to signal any over or underpressure, and thus to prevent any damage to the machinery or the system.
What should the pressure be on a Toyota air conditioner?
If your Toyota’s air conditioning refrigerant recharge kit is equipped with high- and low-pressure gauges, you can use them to help identify when your vehicle’s refrigerant level is adequately pressurized. The low-pressure gauge should read between 25 and 40 psi (pounds per square inch).
