It opens the control circuit when suction pressure drops too low — protecting the compressor from running on a low or lost refrigerant charge, a restricted metering device, or a frozen evaporator coil. It is a common replacement when a unit locks out on low pressure or fails to start in cold ambient conditions.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Low pressure (loss-of-charge) auto-reset switch\u003c\/li\u003e\n\u003cli\u003eOEM part number: 0130M00075\u003c\/li\u003e\n\u003cli\u003eTypical trip point: ~20 PSI open \/ ~45 PSI reset\u003c\/li\u003e\n\u003cli\u003eCompatible model: APH1543M41AC (packaged heat pump)\u003c\/li\u003e\n\u003cli\u003eConnection: Suction-line mount with spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 0130M00075\u003c\/strong\u003e is set to Goodman's factory low-side trip and reset points and uses the correct fitting.
