This normally-open safety switch cuts power to the blower and control circuit the moment the lower access panel is removed, protecting technicians and homeowners from live components and rotating parts. A failed or stuck door switch is one of the most common reasons a furnace will not start after service — replacing it restores the required panel-closed signal to the control board.\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\u003eAction: Normally open, plunger actuated\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana ADV80703BXBB and compatible ADV-series furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Interrupts power when blower door is open\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman OEM switch is built to the exact plunger travel, mounting footprint, and contact rating specified for this furnace, ensuring reliable make\/break and full compatibility with the factory wiring harness.
