This normally-open safety switch cuts power to the blower and control circuit whenever the blower access panel is removed, preventing the furnace from operating with the door open. A failed or stuck switch is a common cause of a furnace that won't start or cycles only when the panel is pressed by hand.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Blower door interlock \/ safety cutoff switch\u003c\/li\u003e\n\u003cli\u003eAction: Normally open, closes when door is installed\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDT070-3B and select Goodman\/Amana gas furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370819\u003c\/li\u003e\n\u003cli\u003eMaterial: Molded housing with plunger actuator and spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM B1370819 guarantees correct plunger travel, terminal spacing, and contact rating for your GDT070-3B.
