The Goodman 10690402S Interlock Door Switch is a genuine OEM safety switch for the AMEC960303ANAB gas furnace and compatible Goodman/Amana models. This normally-open plunger switch closes only when the blower access panel is properly installed, cutting 24V control power (and blower/burner operation) whenever the door is removed. It protects service technicians and prevents the furnace from running with the compartment open.
If your furnace is completely dead — no ignition, no blower, no board activity — and the fault appears only when the panel is on, a stuck or failed door switch is a frequent cause. A bent plunger, cracked housing, or worn contacts will keep the circuit open even with the panel seated.
The genuine OEM 10690402S provides the exact plunger travel, bracket alignment, and contact rating needed to reliably make and break with your specific panel. Generic door switches may mount but misalign with the panel edge, causing intermittent no-heat calls. Because this is a safety interlock, OEM fit is the recommended choice.
Easy (1/5). Disconnect power, remove the mounting screw(s), transfer the two wires, and reinstall. About 10–15 minutes. Verify the plunger depresses fully when the panel is seated.
