The switch continuously monitors refrigerant discharge pressure and interrupts the compressor circuit the moment system pressure exceeds the factory-set limit, protecting the compressor from catastrophic over-pressure damage. When this switch fails or trips without resetting, symptoms include a compressor that won't start, nuisance lockouts, or a system that shuts down shortly after calling for cooling.\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 male port | Rated 6(6)A at 240 VAC | Sensata PS80-03-0018 platform | PMAX 41B certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch, factory-calibrated to exact trip and reset pressures.
