It monitors suction-side pressure and opens the compressor circuit when pressure drops too low — guarding against loss-of-charge, a stuck metering device, or frozen coil conditions that would otherwise slug or overheat the compressor.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130M00075\u003c\/li\u003e\n\u003cli\u003eComponent: Low pressure (loss-of-charge) switch\u003c\/li\u003e\n\u003cli\u003eRefrigerant: R-410A systems\u003c\/li\u003e\n\u003cli\u003eAction: Opens on falling suction pressure to break the control circuit\u003c\/li\u003e\n\u003cli\u003eReset: Factory-calibrated cut-out \/ cut-in (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WPH4436AHAB and select WPH-series packaged units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLike its high-pressure counterpart, this switch's protection depends entirely on correct setpoints. The OEM part is calibrated to the factory low-pressure limits for this system, so it trips exactly when it should. Generic substitutes risk nuisance lockouts or unprotected low-charge operation. Use OEM for reliable compressor protection.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (2\/5).\u003c\/strong\u003e Schrader-mount versions swap without refrigerant recovery; brazed-in versions require recovery and EPA certification. Verify the fitting type before installing.
