The Goodman 10690402S Interlock Door Switch is a genuine OEM safety component designed for the AMEC960603BNAA gas furnace and other compatible Goodman/Amana models. This door interlock switch cuts power to the blower and control circuit whenever the furnace access panel is removed, protecting technicians and homeowners from accidental startup during service.
Our OEM Goodman switch delivers exact-fit tolerances and factory-rated contact life, ensuring the safety circuit trips reliably every time. Generic aftermarket alternatives may cost less but often suffer from inconsistent plunger travel and shorter contact durability, which can cause intermittent no-heat faults. For a critical safety component, OEM is the recommended choice.
Easy — A basic replacement most homeowners can complete in under 15 minutes with a screwdriver. Disconnect furnace power before servicing.
