The high pressure switch monitors refrigerant pressure on the high side of the refrigerant circuit. When system pressure exceeds the rated threshold, the switch opens the control circuit, shutting down the compressor to prevent catastrophic damage. A failed or out-of-calibration pressure switch will cause nuisance lockouts, a compressor that won't start, or — in the opposite failure mode — an unprotected compressor running at dangerously high head pressure.\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 240 VAC | 6(6)A | PMAX 41 Bar | CE \/ EN12263 \/ EN60730-2-6 certified | Factory Authorized Part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part manufactured by Sensata to exact OEM pressure setpoints.
