The Goodman B1370819 is a genuine OEM blower door safety interlock switch for the ADS80904BNA gas furnace and compatible Goodman/Amana models. This normally-open switch cuts power to the furnace whenever the blower access panel is removed, protecting service technicians and homeowners from energized components and moving parts. A worn or missing door switch is a common cause of a furnace that won't start.

Specifications

Type: SPST plunger interlock switch
Action: Opens circuit when blower door is removed
Function: Door / panel safety interlock
Mounting: Blower compartment wall
Fits: Goodman/Amana ADS80904BNA and compatible furnaces

OEM vs. Generic

The OEM B1370819 provides the exact plunger length, bracket, and switch rating Goodman specifies, so the door reliably depresses the plunger and the furnace powers correctly. Generic switches may have mismatched plunger travel, leading to intermittent no-heat faults. Genuine OEM avoids those headaches.

Installation Difficulty

Easy — Disconnect power, unplug the two leads, remove the mounting screws, and snap the new switch into place. About 15 minutes for most installs.
