The high pressure switch continuously monitors refrigerant pressure on the high side of the refrigeration circuit. When system pressure exceeds the rated cutout threshold — caused by a dirty condenser coil, blocked airflow, failed condenser fan motor, or refrigerant overcharge — this switch opens the safety circuit and shuts down the compressor to prevent catastrophic damage. Common failure symptoms include the system entering lockout mode, short-cycling compressor operation, or a no-cooling fault code with no mechanical noise from the compressor.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Cutout: 670 PSI | Reset: 470 PSI | Genuine Carrier OEM Factory Authorized Part | Part Number: 312926-252\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part engineered to exact cutout and reset tolerances.
