The Goodman 10690402S Interlock Door Switch is a genuine OEM blower-compartment safety switch for the Amana/Goodman AMEC961205DNAB gas furnace. This normally-open plunger switch cuts power to the furnace whenever the blower access panel is removed, preventing operation with the door off. A furnace that stays completely dead until the panel is pressed in place usually needs this switch replaced.
Our OEM Goodman door switch has the exact plunger travel and mounting footprint so the panel engages it reliably every time. Generic switches often have a different actuation depth, leading to intermittent no-power faults that are hard to diagnose. For a safety interlock, the genuine part removes the guesswork.
Easy (2/5) — Shut off power, remove the blower panel, unclip the two wire leads and the mounting screw, then install the new switch. Test that the panel fully depresses the plunger. About 15 minutes.
