Installed on the low side of the refrigerant circuit, it opens the compressor control circuit when suction pressure drops too low — a key defense against loss-of-charge, restricted metering, or freeze conditions that would otherwise damage the compressor.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Low pressure cut-out (auto-reset)\u003c\/li\u003e\n\u003cli\u003eCircuit: Normally closed, opens on low pressure\u003c\/li\u003e\n\u003cli\u003eConnection: Low-side refrigerant line with control leads\u003c\/li\u003e\n\u003cli\u003eCompatible model: APH1636M41AA heat pump\u003c\/li\u003e\n\u003cli\u003eOEM part number: 0130M00075\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eFactory calibration matters here. This OEM switch trips and resets at the pressures Goodman engineered for the APH1636M41AA, so the compressor is protected exactly as designed.
