Goodman B1370819 Blower Door Safety Switch

The B1370819 is a genuine OEM blower-compartment door interlock switch engineered for the Goodman/Amana ADV80703BXBB 80% AFUE gas furnace. 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.

Specifications

Part Number: B1370819
Type: Blower door interlock / safety switch
Action: Normally open, plunger actuated
Fits: Goodman/Amana ADV80703BXBB and compatible ADV-series furnaces
Function: Interrupts power when blower door is open

OEM vs. Generic

The 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. Lower-cost generic switches often have different plunger lengths or amperage ratings that can cause intermittent no-heat faults or premature failure. For a safety-critical circuit, OEM is the recommended choice.

Installation Difficulty

Easy (1/5). Typically a 10–15 minute swap: disconnect power, remove the two mounting screws, transfer the spade connectors to the new switch, and reinstall. Basic hand tools only. Always shut off power at the disconnect before servicing.
