The Goodman 10690402S Interlock Door Switch is a genuine OEM blower-compartment safety switch for the Amana/Goodman AMEC960302BNAB gas furnace. This normally-open interlock cuts power to the furnace whenever the blower access panel is removed, preventing the unit from running with the door open. A furnace that is completely dead — no ignition, no blower — often has a stuck or failed door switch.
This OEM Goodman switch matches the exact plunger height and mounting bracket so the door properly depresses the actuator. Generic switches frequently sit at the wrong depth, leaving the furnace intermittently dead even with the panel closed. OEM ensures reliable contact and code-compliant safety operation.
Easy (1 of 5) — One or two mounting screws and two wires. Disconnect power, unclip the wires, swap the switch, and confirm the door depresses the plunger fully. Roughly 15 minutes. Never bypass this safety switch.
