WC\u003c\/strong\u003e for the \u003cstrong\u003eAMH80704BXAA\u003c\/strong\u003e gas furnace and compatible Goodman\/Amana models. It verifies that the inducer\/draft blower is pulling proper negative pressure before allowing ignition. If the flue is blocked, the inducer is weak, or a hose is cracked, the switch stays open and locks out the burners — protecting against incomplete combustion. A stuck or out-of-spec switch is a leading cause of no-heat and ignition lockout faults.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet point:\u003c\/strong\u003e -0.47 in. water column\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact type:\u003c\/strong\u003e Normally open (NO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Draft \/ air-flow proving safety\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e B1370176\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMH80704BXAA and select furnace models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370176\u003c\/strong\u003e is calibrated to Goodman's exact -0.47\" WC trip pressure and port configuration.
