Where is the high pressure switch air conditioning?
The AC pressure switches are located on either side of the AC unit. You will find one switch on the high side and another on the low side. The low-pressure side switch is found before the AC compressor, while the high-pressure switch comes after the compressor.
What is high pressure switch in air conditioning?
A high pressure switch (HPS) and a low pressure switch (LPS) are protective devices for the compressor and refrigeration circuit. The high pressure switch monitors the system for an inoperative outdoor motor, and/or a dirty/restricted condenser (outdoor) coil.
What would cause a high pressure switch to trip?
The most common cause of a refrigerant high-pressure switch tripping in the wintertime is lack of airflow across the indoor coil. One of the signs of lack of airflow is a high temperature split across the indoor coil. Inspect the filter, not just if it is dirty but restrictive.
What to do if your air conditioner has a high pressure switch?
Hopefully, since you cleaned your unit the pressure switch fault will not occur again. If the high-pressure switch continues to flash the high-pressure switch fault code then I would like to suggest that you or a service tech install gauges to see if the pressure is actually high or if the pressure switch is bad.
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.
