A binary pressure switch monitors refrigerant pressure in the air conditioning system. It is designed to interrupt compressor operation when pressure falls too low or climbs too high. If a failed switch is behind your A/C trouble, this unit replaces it.
Four Seasons brings more than 50 years of mobile A/C experience to its products, which are engineered and tested with the aim of providing years of trouble-free service.
Signs this switch may need replacing include an A/C compressor that does not engage, warm air from the vents, or erratic compressor cycling. Low refrigerant and wiring faults can cause the same symptoms, so diagnose the system before replacing parts.
