The Goodman 10690402S Interlock Door Switch is a genuine OEM blower-door safety switch for the AMVC961005DNAA gas furnace and compatible Goodman/Amana models. This normally-open interlock is depressed when the blower access panel is installed, completing the 120V line circuit. Remove the door and the switch opens, cutting power so the furnace cannot run with the compartment exposed. A failed or stuck switch is a common cause of a completely dead furnace.
Our genuine OEM switch matches the factory plunger height, bracket, and terminal spacing so the door engages it correctly every time. Generic switches that sit too high or low may fail to close — leaving the furnace dead — or stay closed and defeat the safety. For a line-voltage interlock, exact fit matters.
Easy (1/5). Disconnect furnace power, unclip the mounting bracket, transfer the two wires, and snap the new switch in place. Under 15 minutes. Test that the plunger fully depresses when the door is reinstalled.
Compatibility note: Goodman and Amana furnaces use this shared OEM part.
