This spring-loaded switch sits inside the blower compartment and cuts 120V power to the furnace whenever the access door is removed. It is a required safety interlock — it prevents the burners and blower from running with the panel open, protecting service technicians and preventing operation without proper combustion-air sealing. A furnace that is completely dead often traces back to a failed or stuck door switch.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Normally-open plunger interlock (door) switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10690402S\u003c\/li\u003e\n\u003cli\u003eFunction: Disconnects line power when blower door is removed\u003c\/li\u003e\n\u003cli\u003eActuation: Spring-loaded plunger closed by the access panel\u003c\/li\u003e\n\u003cli\u003eFit: Goodman \/ Amana furnaces including AMSS921005CNAA\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM\u003c\/strong\u003e switch matches the plunger travel and mounting position so the panel reliably actuates it.
