The \u003cstrong\u003ehigh pressure switch (312926-252, 670-470# cut-out\/cut-in)\u003c\/strong\u003e protects the compressor from dangerously elevated refrigerant pressure, while the \u003cstrong\u003elow pressure switch (312926-258, 55-23# cut-out\/cut-in)\u003c\/strong\u003e guards against loss-of-charge and low-suction conditions. When either switch fails or trips on a fault, the system will lock out, short-cycle, or refuse to start — and fault codes will typically point to a refrigerant pressure or compressor protection error.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — High Pressure Switch (312926-252):\u003c\/strong\u003e 670 PSI cut-out | 470 PSI cut-in | Normally closed | SPST | Factory-matched OEM tolerances for R-410A systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — Low Pressure Switch (312926-258):\u003c\/strong\u003e 55 PSI cut-out | 23 PSI cut-in | Normally closed | SPST | Prevents compressor damage from low refrigerant charge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier pressure switches are calibrated to exact factory setpoints. Generic aftermarket switches routinely ship with ±10–15% pressure tolerances, risking nuisance trips or — worse — failing to protect the compressor at true fault conditions. Only OEM guarantees the setpoint your system was designed around.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 3\/5\u003c\/strong\u003e — Refrigerant system work requires an EPA 608 certification. Recover refrigerant before accessing the refrigerant circuit. Tools needed: manifold gauge set, refrigerant recovery machine, torque wrench, and leak detector.
