This normally-open plunger switch de-energizes the furnace whenever the blower access panel is removed, preventing the unit from running with the door off — a required safety feature. A stuck, broken, or missing door switch is a very common reason a furnace appears completely dead with no lights and no response to a call for heat.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Blower compartment door interlock switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e Normally open, closes when door is installed (plunger actuated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 1\/4 in. quick-connect spade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bracket-mounted at the blower door opening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman \/ Amana GMT140-5 and compatible platforms\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370819\u003c\/strong\u003e matches the original plunger length and bracket so the door closes the contact reliably.
