This normally-closed switch continuously monitors discharge-line refrigerant pressure and opens the low-voltage control circuit if pressure climbs into an unsafe range — protecting the compressor from overload, blocked-condenser conditions, and dirty-coil or fan-failure faults before permanent damage occurs.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e High pressure cut-off (HPCO) switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Compressor high-side over-pressure 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\u003eThis is the factory-specified \u003cstrong\u003eOEM\u003c\/strong\u003e switch with a calibrated trip and reset point matched to Goodman's engineering spec, so the compressor cycles at exactly the pressures the unit was designed for.
