The Goodman 10690402S blower door interlock switch is a direct-fit replacement for the AMEC960303ANAA gas furnace and compatible Goodman/Amana models. This safety switch cuts power to the furnace whenever the blower access panel is removed, preventing the burners and blower from operating with the cabinet open. A failed or stuck door switch is a frequent cause of a completely dead furnace — no ignition, no blower, and no response at the thermostat.
The OEM Goodman switch matches the exact plunger length and mounting footprint so the panel actuates it correctly every time. The Generic option is a quality-matched, budget-friendly equivalent for standard repairs. Both restore the required door-interlock safety cutoff.
Easy (1/5). Turn off power at the furnace, remove the mounting screws, disconnect the two spade terminals, and install the new switch so the access panel depresses the plunger fully when closed. Never tape or jump out a door switch to bypass it — doing so defeats a critical safety interlock. If the furnace only runs with the panel held in, this switch is almost certainly the fix.
Compatible with AMEC960303ANAA. Confirm your model and part number before ordering.
