This interlock cuts power to the furnace whenever the blower access panel is removed, preventing the unit from operating with the door open. A failed or stuck door switch is a common reason a furnace goes completely dead — no ignition, no blower, no control voltage — even though the thermostat is calling.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Blower-door safety interlock switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Factory wire harness \/ leads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e Goodman GMV80905CXA (verify against your rating plate)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e OEM factory interlock assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1370820 comes with the correct plunger length, mounting bracket, and pre-terminated wiring, so it seats and connects without splicing.
