The Goodman 10690402S is a factory-original blower compartment door interlock switch engineered for the AMEC961004CNAB gas furnace and other compatible Goodman/Amana models. This safety switch de-energizes the furnace whenever the blower access panel is removed, preventing the blower and burners from operating with the door open. A worn or stuck interlock switch is a common cause of a furnace that will not start after servicing.
Our OEM option is the exact Goodman-specified switch with guaranteed plunger travel, contact rating, and mounting fit. The Generic equivalent meets the same electrical spec at a lower price point and is a solid choice for budget repairs, though dimensions and bracket alignment may vary slightly.
Easy (1/5). Shut off power at the disconnect, unplug the two spade terminals, unclip or unscrew the old switch, and reverse to install. Typically a 5–10 minute repair with a screwdriver. No refrigerant or gas work required.
