The Goodman B1370819 Door Switch is the genuine OEM blower-door interlock safety for the DDS80904BXA furnace and many other Goodman/Amana models. This plunger-style switch cuts power to the burners and blower whenever the blower-compartment access panel is removed, meeting UL safety requirements. If your furnace only runs when you press the door switch in by hand — or won't run at all with the panel on — a worn interlock is the usual culprit.

Specifications

Type: SPST plunger / door interlock safety switch
Function: De-energizes furnace when blower door is open
Actuation: Normally open, closes when panel is installed
Fits model: Goodman DDS80904BXA and compatible furnaces
OEM part number: B1370819

OEM vs. Generic

The OEM Goodman switch matches the factory bracket, plunger height, and wire harness so the door panel actuates it correctly on the first install. Generic interlock switches frequently have the wrong plunger travel or mounting pattern, leading to intermittent operation on a component that is literally a life-safety device. OEM is strongly recommended here.

Installation Difficulty

Easy–Moderate (2/5) — Mounts with screws or a clip and two wire terminals in a tight cabinet corner. Kill power at the disconnect before starting. Allow 20–30 minutes; a flashlight and a nut driver make it simple.
