The Goodman 10690402S Interlock Door Switch is a genuine OEM blower-compartment safety switch for the AMVC960403BNBA gas furnace. This plunger-style interlock cuts power to the furnace whenever the blower access panel is removed, preventing the unit from operating with the door open. A stuck, broken, or bent door switch is a frequent cause of a completely dead furnace — no display, no blower, no ignition — because the safety circuit never closes.
The OEM Goodman door switch has the exact plunger height and bracket geometry so it actuates correctly when the panel is seated. Generic switches often sit at the wrong depth, leaving the furnace dead or the safety defeated. OEM ensures proper actuation.
Easy — One or two screws and two spade terminals inside the blower compartment. Cut power, swap the switch, and confirm the plunger depresses fully when the door is reinstalled.
