Manufactured by Sensata, this SPST pressurestat continuously monitors refrigerant discharge pressure on the high side of the refrigeration circuit. When head pressure exceeds the factory-set cutout threshold, the switch opens the control circuit to shut down the compressor — protecting it from catastrophic damage due to blocked condenser coils, overcharge, or high ambient conditions. When the system faults, you'll typically see the unit locking out on a high-pressure fault code, short-cycling at startup, or failing to cool while the outdoor fan continues to run.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | SPST (Normally Closed) | 24V \/ 2A control circuit | 1\/8\"-NPT refrigerant port | 42\" lead length | Quick-connect electrical terminals | 240 VAC rated | Manufactured by Sensata (Carrier Factory Authorized)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier\/Sensata OEM switch, not an aftermarket clone. OEM units are factory-calibrated to exact PSI setpoints — generic switches frequently have ±5–10% PSI variance that can allow unsafe head pressure before cutoff or cause nuisance trips at normal operating pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Requires recovery of refrigerant before replacing the switch if the port is in a live refrigerant line. Tools needed: manifold gauge set, refrigerant recovery machine, adjustable wrench, and a multimeter to confirm switch continuity before and after replacement. Always follow EPA 608 protocols.
