Pressure Switches
Pressure switches are safeties installed on units to protect the unit, compressor, and anyone working on the unit. Pressure switch trip points vary from unit to unit and with the type of refrigerant in the unit. Usually, there are 2 types of pressure switches, HIGH PRESSURE switches and LOW PRESSURE switches.
It is important to remember that there are multiple causes for safeties tripping. A complete diagnostic of the refrigerant side of the system is necessary to determine the cause of the safety tripping. Pressures are one part of the diagnostic but so is super heat, subcooling, and amp draw of the compressor along with electrical diagnostics.
High Pressure Switch
Prevents system damage due to excessive pressure by disabling A/C compressor when pressure exceeds set point. Allows compressor to resume when pressure drops below reset point. Mounted on or near receiver dryer.
Fan Trigger Switch
Turns on engine cooling fan to lower system pressure when set point pressure is reached, either directly or by signaling Engine Control Module. Mounted on high pressure side of compressor.
Low Pressure Switch
Prevents system damage due to low pressure or low refrigerant charge by disabling A/C compressor when pressure drops below reset point. Allows compressor to resume when pressure rises above set point. Mounted on low pressure side of compressor.
Set Point
Rising pressure at which switch actuates. In PSI (pounds per square inch).
Reset Point
Falling pressure at which switch returns to normal state. In PSI (pounds per square inch)
Remember, a complete diagnostic of the system should always be performed before replacing any part. There is nothing worse than replacing a part and still having the unit malfunction. Hope this helps!
