This spring-loaded plunger switch de-energizes the furnace whenever the blower compartment door is removed, preventing the unit from running with the panel off — a code-required safety interlock. A furnace that won't start after service is very often caused by a worn or misaligned door switch.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: SPST normally-open plunger interlock switch\u003c\/li\u003e\n\u003cli\u003eFunction: Cuts 120V control power when blower door is open\u003c\/li\u003e\n\u003cli\u003eOEM part number: 10690402S\u003c\/li\u003e\n\u003cli\u003eCompatibility: AMVM970603BNBA and select AMVM97 furnaces\u003c\/li\u003e\n\u003cli\u003eMounting: Bracket-mounted at the blower door frame\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 10690402S\u003c\/strong\u003e matches the exact plunger travel and bracket geometry of the AMVM97 cabinet, so the door reliably actuates it. Universal interlock switches are cheaper but frequently require bracket modification and can under- or over-travel, leading to intermittent no-heat calls. For a clean, reliable fit we recommend OEM.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eTurn off power at the disconnect, unplug the two quick-connect terminals, remove the mounting screw, and install the replacement. Verify the door depresses the plunger fully when closed. Typical time is 10–15 minutes with no special tools.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058003886451,"sku":"GOODMAN-9256","price":18.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-interlock-door-switch-for-amvm970603bnba-10690402s","provider":"National HVAC Parts","version":"1.0","type":"link"}
