The Goodman 10690402S Interlock Door Switch is a genuine OEM blower-door safety switch for the AMSS921005CNAA gas furnace. This spring-loaded switch sits inside the blower compartment and cuts 120V power to the furnace whenever the access door is removed. It is a required safety interlock — it prevents the burners and blower from running with the panel open, protecting service technicians and preventing operation without proper combustion-air sealing. A furnace that is completely dead often traces back to a failed or stuck door switch.

Specifications

Type: Normally-open plunger interlock (door) switch
OEM Part Number: 10690402S
Function: Disconnects line power when blower door is removed
Actuation: Spring-loaded plunger closed by the access panel
Fit: Goodman / Amana furnaces including AMSS921005CNAA
Equipment: Gas furnace

OEM vs. Generic

The genuine OEM switch matches the plunger travel and mounting position so the panel reliably actuates it. Generic switches may not align with the door's contact point, leaving the furnace intermittently dead or, unsafely, always powered. For a code-required interlock, use the OEM part.

Installation Difficulty

Easy (2/5). Mounts with one or two screws and connects via spade terminals. Disconnect furnace power first. After installing, verify the switch closes fully when the blower door is seated and opens when it's removed.
