Manufactured by Sensata (PS80-03-0018), it monitors refrigerant discharge pressure on the high side of the refrigeration circuit. When pressure exceeds the cutout threshold, the switch opens to protect the compressor from catastrophic damage. A failed or stuck-open switch typically results in nuisance trips, compressor short-cycling, or a system that locks out immediately on startup with a high-pressure fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 6(6)A @ 240 VAC | 1\/8\" NPT fine-thread port | PMAX 41B | Sensata PS80 series | Cross-references: HK02ZA395A, PS80-03-0018, P332-1103, 312926-217, HK02ZA380, HK02ZA400, HK02ZA401, HK02ZA435\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized part. OEM pressure switches are calibrated to exact cutout\/cut-in tolerances at the factory — generic aftermarket units often drift outside ±5 PSI spec, risking either false trips or — worse — inadequate compressor protection under true high-pressure events.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 3\/5\u003c\/strong\u003e — Refrigerant circuit work requires EPA 608 certification. Recover refrigerant before disconnecting the switch port. Tools needed: manifold gauge set, refrigerant recovery machine, adjustable wrench, thread sealant tape. Always confirm system pressure is zero before removal. Reconnect wiring with the correct quick-connect terminals and torque the port fitting to spec.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
