The Goodman 10690402S is a genuine OEM blower-door interlock switch for the AMES960805CNAA gas furnace and compatible Goodman/Amana equipment. This safety switch cuts electrical power to the furnace whenever the blower access panel is removed, preventing the unit from running with the door off. A failed or stuck door switch is a frequent cause of a completely dead furnace — no display, no blower, no ignition.
The OEM 10690402S has the correct plunger length and bracket alignment so the panel actuates it reliably every time. Generic door switches may not seat properly against this cabinet, leading to intermittent power loss. OEM ensures dependable operation and warranty compliance for a safety-listed component.
Easy (1/5). Two screws and two spade terminals; typically under 15 minutes. Shut off power at the breaker before servicing. After installing, confirm the panel fully depresses the plunger so the furnace powers up with the door closed.
