The Goodman 10690402S is a genuine OEM interlock door safety switch built for the AMEC960803BNAA gas furnace and other compatible Goodman and Amana units. This switch cuts power to the furnace whenever the blower access panel is removed, protecting technicians and homeowners from live electrical and moving blower components. If your furnace won't power on, a stuck or broken door switch is a frequent culprit.
The OEM Goodman switch matches the exact plunger height and mounting geometry of your furnace cabinet, so the panel engages the switch correctly every time. Generic switches may not seat properly, leaving the furnace dead or the safety defeated. For a safety device, OEM is the reliable choice.
Easy — A quick 10–15 minute swap. Disconnect power, unclip the two spade terminals, unscrew the switch, and mount the replacement. No calibration required.
