The low pressure switch continuously monitors refrigerant pressure on the suction side of the system. When refrigerant pressure drops below the factory-set threshold — due to a leak, blocked filter, or low charge — the switch opens and shuts down the compressor to prevent catastrophic damage. Common failure symptoms include the system locking out on a low-pressure fault, the compressor cycling off shortly after startup, or the unit running but delivering no cooling or heating.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 55-23# pressure rating | Cut-out: 55 PSIG | Cut-in: 23 PSIG | OEM Sensata \/ Factory Authorized Parts designation | Pre-wired leads for direct plug-in installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part (312926-258), precision-calibrated to factory cut-in\/cut-out tolerances.
