This plunger-style switch de-energizes the furnace whenever the blower access panel is removed, preventing the unit from operating with the door open. A furnace that is completely dead — no ignition, no blower, no board lights — very often has a stuck or failed door switch.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 10690402S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Normally-open plunger interlock switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Cuts line voltage when the blower door is off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e AMES921005CNAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuation:\u003c\/strong\u003e Spring-loaded plunger, panel-activated\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM switch matches the exact plunger height, contact rating, and bracket footprint so the door reliably depresses it when closed.
