The low pressure switch continuously monitors refrigerant circuit pressure on the suction side of the system. When pressure drops below the factory cut-in threshold — typically due to low refrigerant charge, a blocked filter drier, or a faulty metering device — the switch opens the control circuit to protect the compressor from running under damaging low-pressure conditions. Common failure symptoms include the system not starting, short-cycling, or tripping into a lockout fault code with no apparent cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 55-23# pressure rating (cuts out at 23 PSI, resets at 55 PSI) | Brass inlet connector | Precision-calibrated diaphragm | Factory Authorized Parts (FAP) designation | OEM part number 312926-258\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine Carrier FAP switch is calibrated to exact factory pressure thresholds.
