It continuously monitors refrigerant circuit pressure on the high side and cuts power to the compressor when pressure exceeds a safe threshold, protecting the compressor from catastrophic failure. A failed or out-of-spec switch typically causes one of two symptoms: nuisance high-pressure lockouts on hot days (switch opens prematurely) or, if the switch fails open, a compressor that runs without safety protection. Replacing with the exact OEM switch restores factory-calibrated protection.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 406\/300 rating | 6(6)A | 240 VAC | PMAX 41B | Sensata-manufactured | Carrier Factory Authorized Part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part — factory-set trip points guarantee your compressor cuts out at the correct pressure.
