Replacement Parts

Frequently Asked Questions

A high pressure switch is a safety device that is used to turn off power to an air conditioning unit in the case of excessive refrigerant pressure.
If your AC system is not cooling properly or has low airflow, this may indicate that the high pressure switch needs to be repaired. It can also be tested with a multimeter for proper operation.
To replace the defective high pressure switch, first disconnect power from the unit and then remove the access panel. Locate the faulty switch and carefully unscrew it before replacing it with a new one. Be sure to follow all safety instructions when working on any electrical component.
