The \u003cstrong\u003ehigh pressure switch (312926-252, rated 670-470 PSI)\u003c\/strong\u003e protects the refrigerant circuit from dangerous over-pressure conditions, cutting power to the compressor before system damage can occur. The \u003cstrong\u003elow pressure switch (312926-258, rated 55-23 PSI)\u003c\/strong\u003e monitors suction-side pressure and shuts the compressor down when pressure drops too low — a common indicator of low refrigerant, a frozen coil, or a blocked filter. Together, these two switches are the primary compressor protection layer on your Carrier heat pump. When either switch fails or trips and will not reset, the system will typically lock out on a fault code and refuse to run heating or cooling until the switch is replaced and the underlying refrigerant issue (if any) is resolved.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Pressure Switch Specs:\u003c\/strong\u003e Part 312926-252 | Cut-out: 670 PSI | Cut-in: 470 PSI | OEM-matched single-pole normally-closed contact | Factory Authorized Parts (FAP)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Pressure Switch Specs:\u003c\/strong\u003e Part 312926-258 | Cut-out: 55 PSI | Cut-in: 23 PSI | OEM-matched single-pole normally-open contact | Factory Authorized Parts (FAP)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e These are genuine Carrier Factory Authorized Parts — not aftermarket.
