Wired into the 24V control circuit, this normally-closed switch senses suction-line pressure and opens the circuit when it drops too low — protecting the compressor from a loss-of-charge, a frozen coil, or restricted refrigerant flow that would otherwise cause the compressor to run dry and overheat.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e Low pressure (loss-of-charge) switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Compressor low-side protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact configuration:\u003c\/strong\u003e Auto-reset, normally closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit:\u003c\/strong\u003e 24V low-voltage control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman APH1648H41AB heat pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM\u003c\/strong\u003e 0130M00075 is factory-calibrated to Goodman's exact cut-out and cut-in pressures, ensuring the compressor is protected without nuisance trips on cold-weather startups.
