This spring-plunger safety switch mounts inside the blower compartment and de-energizes the furnace whenever the blower access door is removed. It is a code-required safeguard that prevents the burners and blower from running with the door open, protecting technicians from moving parts and stopping combustion-air problems during service.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: normally-open plunger interlock switch\u003c\/li\u003e\n\u003cli\u003eSupplied with: factory wire leads (pre-wired)\u003c\/li\u003e\n\u003cli\u003eFunction: blower-door safety cutoff \/ interlock\u003c\/li\u003e\n\u003cli\u003eAction: circuit opens when door is removed\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DMS80703ANA and select 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370820\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman assembly arrives with the correct plunger travel, bracket, and pre-attached harness so it lands in the factory location and mates to the furnace wiring without splicing guesswork. Generic door switches often need custom brackets or wire adapting, and a poorly positioned plunger can leave the furnace dead or defeat the safety entirely. OEM saves time and keeps the interlock code-compliant.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Easy (2\/5)\u003c\/h3\u003e\u003cp\u003eDisconnect power, remove the old switch bracket screws, unplug or splice the two leads, mount the new switch so the plunger is depressed when the door is on, and reconnect. Ten to fifteen minutes. Verify the furnace powers off when the door is pulled.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058031411571,"sku":"GOODMAN-9579","price":40.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-blower-door-safety-switch-w-wires-b1370820","provider":"National HVAC Parts","version":"1.0","type":"link"}
