Together, these switches form the system's primary refrigerant circuit protection, continuously monitoring operating pressures and shutting down the compressor before unsafe conditions cause catastrophic damage. A failed high pressure switch typically causes nuisance high-pressure lockouts or allows the compressor to run in an over-pressurized state. A failed low pressure switch results in the compressor running during low-charge or restricted-airflow conditions, causing compressor flooding or burnout. Replace both as a set for a complete pressure-safety restoration.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers \u0026amp; Specs:\u003c\/strong\u003e 312926-252 High Pressure Switch — 670 PSI cut-out \/ 470 PSI cut-in | 312926-258 Low Pressure Switch — 55 PSI cut-out \/ 23 PSI cut-in | Both are factory-authorized OEM Carrier replacement parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are factory-calibrated to exact cut-in\/cut-out setpoints. Aftermarket switches frequently carry ±10–15% pressure tolerances, risking nuisance trips or, worse, failing to protect the compressor under true fault conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 3\/5\u003c\/strong\u003e — Refrigerant circuit work must be performed by an EPA 608-certified technician.
