The \u003cstrong\u003ehigh pressure switch (312926-252, 670\/470 PSI)\u003c\/strong\u003e monitors refrigerant discharge pressure and shuts down the compressor if pressure exceeds safe limits — protecting the system from catastrophic failure. The \u003cstrong\u003elow pressure switch (312926-258, 55\/23 PSI)\u003c\/strong\u003e guards against low-charge or loss-of-refrigerant conditions by cutting power to the compressor before damage occurs. Common failure symptoms include hard lockouts, nuisance tripping, or a unit that short-cycles and won't stay running. A failed pressure switch often triggers a fault code on the control board before any other component is tested.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e 312926-252 (High Pressure Switch, 670\/470 PSI cutout\/reset) | 312926-258 (Low Pressure Switch, 55\/23 PSI cutout\/reset) — both are genuine Carrier Factory Authorized Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are factory-calibrated to exact PSI setpoints for the PH14NB06000GAAAA refrigerant circuit.
