The high pressure switch continuously monitors refrigerant discharge pressure on the high side of the refrigeration circuit. When pressure exceeds the rated cutout threshold — typically caused by a dirty condenser coil, failed condenser fan motor, refrigerant overcharge, or a blocked liquid line — the switch opens, sending a fault signal to the control board and shutting down the compressor to prevent catastrophic damage. Once the condition is corrected and pressure drops back to the close setpoint, the switch resets. Failure symptoms include nuisance high-pressure lockouts, system short-cycling with a fault code, or a compressor that won't run even after reset attempts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 240 VAC rated | 1\/8\" NPT male fitting | Sensata \/ Pressurestat series | Cross-reference: HK02ZA395A, PS80-03-0018, 406-300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part manufactured to factory tolerance.
