The \u003cstrong\u003ehigh pressure switch (312926-252, rated 670-470 PSI)\u003c\/strong\u003e monitors refrigerant discharge pressure and shuts the compressor down before dangerously high pressure can cause mechanical failure. The \u003cstrong\u003elow pressure switch (312926-258, rated 55-23 PSI)\u003c\/strong\u003e guards the compressor against operating in a low-charge or restricted-airflow condition. Together, these two switches form the primary refrigerant-circuit safety net for your system. When either switch fails or trips without reset, you'll typically see a compressor lockout fault code, short-cycling, or a unit that runs the indoor blower but never engages the outdoor compressor.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — High Pressure Switch (312926-252):\u003c\/strong\u003e 670 PSI cut-out \/ 470 PSI cut-in | Refrigerant-side protection | Factory Authorized Part | Replaces: 312926252\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — Low Pressure Switch (312926-258):\u003c\/strong\u003e 55 PSI cut-out \/ 23 PSI cut-in | Compressor loss-of-charge protection | Factory Authorized Part | Replaces: 312926258\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are factory-calibrated to exact cut-in\/cut-out thresholds.
