The high pressure switch monitors the refrigerant circuit for dangerous over-pressure conditions and cuts power to the compressor before damage occurs. The low pressure switch guards against low-charge or refrigerant loss scenarios that would cause the compressor to run unprotected. When either switch fails, the most common symptoms are \u003cstrong\u003ehard lockout after startup\u003c\/strong\u003e, \u003cstrong\u003eshort-cycling within 30–60 seconds\u003c\/strong\u003e, or a system that runs in fan-only mode with no heating or cooling output.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e 312926-252 (High Pressure Switch, 670 cut-out \/ 470 cut-in PSI) | 312926-258 (Low Pressure Switch, 55 cut-out \/ 23 cut-in PSI) | Factory Authorized Carrier OEM parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are factory-calibrated to exact PSI set points for the PH13NB060000ABAA refrigerant circuit.

Verify your unit's data plate refrigerant type and confirm existing switch wiring color codes before disconnecting. Selling both switches together eliminates repeat service calls — if one has failed from age or overload, the second is typically near end-of-life as well. Questions about fitment?
