The high pressure switch is a critical refrigerant-circuit safety control: it continuously monitors refrigerant pressure on the high side and opens the circuit to shut down the compressor when pressure exceeds a safe threshold — protecting your system from catastrophic compressor failure. Common symptoms of a failed high pressure switch include nuisance lockouts, the compressor refusing to start, or the system tripping on a high-pressure fault code with no apparent refrigerant issue.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Cut-out at 670 PSI | Reset at 470 PSI | Factory-matched OEM tolerances | Certified to EN12263 and EN60730-2-6 standards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, manufactured to exact pressure cut-out and reset specifications.
