This refrigerant-side safety device continuously monitors system discharge pressure and opens the circuit at \u003cstrong\u003e395 PSI\u003c\/strong\u003e to protect the compressor from catastrophic over-pressure failure, resetting once pressure drops back to \u003cstrong\u003e295 PSI\u003c\/strong\u003e. When this switch fails or trips, you'll typically experience nuisance lockouts, a compressor that shuts off shortly after startup, or an outright no-cooling fault code — symptoms that are easy to misdiagnose as a refrigerant or compressor problem.\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 thread | 6(6)A rated | 240 VAC | Sensata PS80 platform (OEM: HK02ZA395A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part manufactured to exact factory pressure tolerances.
