This plunger-style switch cuts power to the burners and blower whenever the blower-compartment access panel is removed, meeting UL safety requirements. If your furnace only runs when you press the door switch in by hand — or won't run at all with the panel on — a worn interlock is the usual culprit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e SPST plunger \/ door interlock safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e De-energizes furnace when blower door is open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuation:\u003c\/strong\u003e Normally open, closes when panel is installed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e Goodman DDS80904BXA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e B1370819\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch matches the factory bracket, plunger height, and wire harness so the door panel actuates it correctly on the first install. Generic interlock switches frequently have the wrong plunger travel or mounting pattern, leading to intermittent operation on a component that is literally a life-safety device.
