This normally open switch de-energizes the furnace when the blower access panel is removed, protecting service technicians and preventing operation with the door off. If your furnace only runs when the door panel is pressed by hand, or won't start at all, a failed or misaligned door switch is the likely cause.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B1370819\u003c\/li\u003e\n\u003cli\u003eType: Blower door interlock safety switch\u003c\/li\u003e\n\u003cli\u003eContact: Normally Open (closes when panel is installed)\u003c\/li\u003e\n\u003cli\u003eFunction: Cuts power when access panel is removed\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GUP100-4A furnace\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM switch has the correct plunger height and mounting bracket geometry so the panel reliably actuates it.
