The AC pressure switch is a safety switch that is mounted on both the high and low sides of the air conditioning system. Depending on which side of the system the sensor is mounted in, when the pressure rises too high or drops too low, the switch will turn off the compressor to prevent damage from occurring.Click to see full answer. Subsequently, one may also ask, how do I know if my AC high pressure switch is bad?The most common symptom of a bad AC pressure switch is most likely that you will notice that the AC compressor is cutting on and off rapidly when you are idling your car. These switches between on and off can be noticeable on the engine’s rpm, and you may see or feel fluctuations from it.Subsequently, question is, how do you replace a high pressure switch on an air conditioner?

Step 2: Reinstall the electrical connector. Step 4: Test the A/C. Likewise, people ask, 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 causes a high pressure switch to trip?Pressure switch trip points vary from unit to unit and with the type of refrigerant in the unit. What causes the high pressure switch to trip? Most common cause is a dirty condenser coil. just because the outside looks clean, don’t forget that some units have splitcondenser coils and the inner coil could be dirty.
