The Goodman 10690402S Interlock Door Switch is a genuine OEM safety component for the Amana/Goodman AMEC960603BNAB gas furnace. This blower-compartment door switch cuts power to the furnace whenever the access panel is removed, preventing the unit from operating with the door open — a critical safeguard against fan injury and combustion-air problems.
The OEM Goodman 10690402S matches the exact plunger travel and mounting bracket of your furnace. Generic door switches frequently sit at the wrong depth, leaving the furnace dead even with the panel installed, or failing to break the circuit at all. OEM removes the guesswork.
Easy (1/5). Turn off power, remove the two wire leads, unclip or unscrew the switch from its bracket, and install the replacement. Under 15 minutes with a screwdriver. If your furnace shows no power at all, this switch is one of the first things to check — a stuck or broken interlock is a common no-heat cause.
Restore safe operation with the genuine Goodman 10690402S door interlock switch.
