The high pressure switch monitors refrigerant discharge pressure on the high side of the refrigerant circuit. When system pressure exceeds the factory-set threshold — typically caused by a dirty condenser coil, failed condenser fan motor, overcharge, or a blocked refrigerant circuit — the switch opens to protect the compressor from catastrophic damage. Symptoms of a failed switch include nuisance high-pressure lockouts, a system that trips off on warm days but not cool ones, or a compressor that won't engage after a manual reset.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at \u003cstrong\u003e395 PSI\u003c\/strong\u003e | Closes at \u003cstrong\u003e295 PSI\u003c\/strong\u003e | Rated 6(6)A @ 240 VAC | PMAX 41B | 1\/8\" NPT thread | Sensata PS80-03-0018 platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part manufactured to exact factory pressure setpoints.
