It monitors suction-side (low-side) refrigerant pressure and opens the compressor circuit if pressure drops too low — the classic loss-of-charge and frozen-coil protection. This prevents the compressor from running under a leak or restricted-flow condition, which would otherwise cause slugging, overheating, and early failure. A stuck-open or failed switch will keep the system from starting.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130M00075\u003c\/li\u003e\n\u003cli\u003eFunction: Low-side (suction) pressure cut-out \/ loss-of-charge protection\u003c\/li\u003e\n\u003cli\u003eType: Auto-reset pressure control, normally closed\u003c\/li\u003e\n\u003cli\u003eCompatible Model: APH1636H41AB (Goodman\/Amana packaged heat pump)\u003c\/li\u003e\n\u003cli\u003eConnection: OEM refrigerant fitting with electrical spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM switch is set to the factory low-pressure cut-out and reset points for this platform.
