Mounted on the high side of the refrigerant circuit, this pressurestat continuously monitors system pressure and cuts power to the compressor the moment refrigerant pressure exceeds the safe operating threshold. When this switch fails or trips, the system will either short-cycle, lockout on a fault code, or refuse to run cooling entirely — symptoms often misdiagnosed as a bad control board or refrigerant leak.\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 male thread | Sensata PS80 platform | PMAX 41B rated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part.
