Mounted on the high-side refrigerant line, this switch continuously monitors system discharge pressure and opens the compressor circuit if pressure exceeds the safe threshold — protecting the compressor from catastrophic over-pressure failure. When it fails or trips repeatedly, you'll see nuisance high-pressure lockouts, compressor short-cycling, or a system that won't run at all even when refrigerant charge and airflow are confirmed normal.\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\"-Fine NPT thread | Sensata PS80-03-0018 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 with factory-calibrated trip points.
