The high pressure switch is a critical refrigerant-circuit safety device that monitors discharge-side pressure and cuts power to the compressor the moment system pressure exceeds a safe threshold. When this switch fails or trips, you'll typically experience nuisance lockouts, a compressor that won't run, or fault codes indicating a high-pressure trip — symptoms that can be caused by a faulty switch even when actual refrigerant pressures are normal.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 1\/8\" NPT male thread connection | 240 VAC rated | SPST normally-closed contact | Sensata PS80-03-0018 (OEM equivalent)\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-out and cut-in pressures.
