The genuine Goodman 10690402S Interlock Door Switch is a factory OEM safety component for the Amana/Goodman AMEC960302BNAA 96% AFUE gas furnace. This blower-compartment interlock switch de-energizes the furnace whenever the access panel is removed, protecting technicians and homeowners from moving blower components and live electrical connections during service.
Genuine Goodman door switches match the exact plunger length and mounting footprint required for reliable panel actuation. Generic substitutes often have the wrong throw depth, leaving the furnace unable to start with the door properly installed — a common cause of "no-heat" service calls. OEM eliminates that guesswork.
Easy (1/5). Cut power to the furnace, unclip or unscrew the old switch, transfer the two wire leads, and snap the replacement into the bracket. Typical replacement takes 10–15 minutes with only a screwdriver.
Keep your furnace's factory safety interlock working correctly with this genuine Goodman replacement switch.
