The Goodman 10690402S is a genuine OEM blower-door interlock switch and a direct-fit replacement for the Amana/Goodman AMEC960402BNAB gas furnace. This safety switch cuts power to the furnace whenever the blower-compartment door is removed, protecting service technicians and homeowners. A failed door switch is a frequent reason a furnace appears completely dead with no lights or blower operation.
The OEM 10690402S has the correct plunger travel and mounting geometry so the door reliably actuates the switch. Generic switches may not seat correctly, leaving the furnace either dead or unsafely powered with the door off. OEM is the safe, reliable choice.
Easy to moderate. Cut power, remove the blower panel, unscrew the switch bracket, and transfer the two wires. About 15–20 minutes.
