The high pressure switch monitors refrigerant pressure on the high side of the refrigeration circuit and opens the safety circuit when pressure exceeds the factory setpoint — shutting down the compressor before damaging levels are reached. A failed or weak pressure switch typically causes nuisance high-pressure lockouts, compressor fault codes, or a system that trips on a warm day even with proper refrigerant charge. Always verify the pressure switch before condemning a compressor.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 1\/8\" NPT thread connection | Sensata PS80-03-0018 platform | 240 VAC rated | SPST normally closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier factory part — not an aftermarket substitute.
