Pressure switches are refrigerant-circuit safety devices: the high-pressure switch (HPS) opens on dangerous high-side pressure, cutting the compressor to prevent damage, while the low-pressure switch (LPS) opens when suction pressure drops too low — often indicating a refrigerant leak or metering issue. Symptoms of a failed pressure switch include the system locking out on start-up, nuisance trips with no clear refrigerant fault, or the compressor refusing to energize despite the thermostat calling for cooling or heating.\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 | SPST-NC | Factory-matched Carrier OEM | Genuine LF18-094 series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — Low Pressure Switch (312926-258):\u003c\/strong\u003e Factory OEM low-side cut-out | SPST-NC | Engineered to match PH15NA06000GBAAA refrigerant circuit operating pressures\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM switches use factory-calibrated set points critical for R-410A operating pressures.
