Wired into the control circuit on the suction side, it opens when refrigerant pressure drops too low — guarding the compressor against loss-of-charge and low-suction conditions that lead to coil freezing or compressor slugging. A failed switch causes short-cycling or no protection.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130M00075\u003c\/li\u003e\n\u003cli\u003eType: Low-pressure (loss-of-charge) safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Opens control circuit on low suction pressure\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003eFits: WPH4330AHAB packaged heat pump\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGeneric low-pressure switches frequently differ in cut-out\/cut-in set points and port fittings.
