The \u003cstrong\u003ehigh pressure switch (312926-252, rated 670-470 psi)\u003c\/strong\u003e monitors refrigerant discharge pressure and opens the circuit if pressure climbs dangerously high — protecting the compressor from catastrophic failure. The \u003cstrong\u003elow pressure switch (312926-258, rated 55-23 psi)\u003c\/strong\u003e guards against low-refrigerant or loss-of-charge conditions that can cause the compressor to run dry. Together, they form the primary refrigerant safety circuit. Common failure symptoms include nuisance high- or low-pressure lockouts, a system that trips off shortly after startup, or fault codes on the thermostat or control board indicating a pressure-circuit open.\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 | Automatic reset | Factory Authorized Carrier OEM part | Replaces legacy p\/n 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 | Automatic reset | Factory Authorized Carrier OEM part | Sensata \/ PS80-02 platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches are precision-calibrated at the factory to exact cut-in\/cut-out setpoints.
