The high pressure switch continuously monitors refrigerant discharge pressure and opens the circuit to shut down the compressor if pressure rises to an unsafe level. When it fails or trips permanently, the system will lock out on a high-pressure fault, short-cycle, or refuse to run the compressor altogether — symptoms often misdiagnosed as a refrigerant overcharge or a failed control board.\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 connection | 240 VAC rated | SPST normally-closed contact | Sensata PS80 platform (OEM part 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 setpoints (±2%).
