Pressure switches are refrigerant-circuit safety controls: the high pressure switch trips when system pressure exceeds safe operating limits to protect the compressor from over-pressurization, while the low pressure switch opens on a loss-of-charge condition to prevent compressor damage from inadequate lubrication. A failed pressure switch typically causes nuisance lockouts, a system that starts then immediately shuts down, or a unit that refuses to enter the heating or cooling cycle at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers \u0026amp; Specs:\u003c\/strong\u003e High Pressure Switch — OEM Part# 312926-252 | Set Point: 670 PSI cut-out \/ 470 PSI cut-in | Low Pressure Switch — OEM Part# 312926-258 | Set Point: 55 PSI cut-out \/ 23 PSI cut-in | Factory Authorized Parts (Carrier RCD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Genuine Carrier OEM pressure switches are factory-calibrated to exact set-point tolerances. Aftermarket substitutes often carry wider PSI tolerances, risking false trips or — more dangerously — failure to trip under a true fault condition, leaving your compressor unprotected.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 3\/5\u003c\/strong\u003e — Refrigerant circuit work must be performed by an EPA Section 608 certified technician. The system must be recovered before replacing refrigerant-side pressure switches. Tools required: manifold gauge set, recovery machine, refrigerant scale, multimeter, and 1\/4\" flare fitting tools.
