Mounted on the refrigerant circuit, this switch continuously monitors system high-side pressure and cuts power to the compressor if pressure exceeds the safe threshold — protecting your compressor from catastrophic failure. A failed or faulty high-pressure switch will typically trigger nuisance lockouts, trip a fault code on the control board, or cause the system to shut down immediately after startup even when refrigerant charge and airflow are normal.\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 | 1\/8\" NPT thread fitting | 240 VAC rated | Sensata PS80-03-0018 platform | SPST normally closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine Carrier OEM switch is factory-calibrated to exact cut-in\/cut-out tolerances.
