Pressure switches monitor refrigerant circuit pressures and protect the system by shutting it down when pressures fall outside safe operating ranges. A failed pressure switch commonly causes the unit to trip into lockout, refuse to start, or cycle off immediately after startup — even when refrigerant charge and refrigerant pressures are within normal range.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 312926-252 — High Pressure Switch, factory-calibrated cutout set point | 312926-258 — Low Pressure Switch, factory-calibrated cutout set point | Direct OEM replacement | Designed for R-410A refrigerant systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact factory cutout and reset pressures.
