Also called a door interlock switch, it de-energizes the furnace whenever the blower-compartment panel is removed, so the burners and blower cannot run with the door open. A failed door switch is a common cause of a completely dead furnace that shows no power or ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: blower door interlock safety switch\u003c\/li\u003e\n\u003cli\u003eIncludes: pre-attached wire leads (plug-and-play harness)\u003c\/li\u003e\n\u003cli\u003eFunction: cuts furnace power when access panel is removed\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DMS80905CNA and compatible 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 OEM B1370820 arrives with the correct connector and wire leads already installed, so it drops straight into the Goodman harness with no splicing or terminal crimping. Generic switches often require you to cut and re-wire, introducing failure points on a code-required safety interlock.

Turn off electrical power, remove the blower panel, unclip the old switch from its bracket, unplug the harness connector, and snap in the replacement. Route the new wires along the original path and reconnect. If the furnace still won't power up, have a licensed HVAC technician check the low-voltage circuit and control board.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058048418163,"sku":"GOODMAN-9614","price":54.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-blower-door-safety-switch-w-wires-for-dms80905cna-b1370820","provider":"National HVAC Parts","version":"1.0","type":"link"}
