The Goodman 10690402S Interlock Door Switch is a genuine OEM safety switch for the Goodman ACVC960804CNBA gas furnace and compatible Goodman/Amana models. Mounted on the blower compartment, this interlock switch automatically disconnects line voltage to the furnace whenever the blower access door is removed — preventing the unit from operating with the panel off and protecting technicians from electrical and moving-part hazards. A failed door switch is a frequent cause of a furnace that won't power on with the door closed.
This genuine Goodman OEM door switch matches the exact plunger length, bracket, and electrical rating required by the ACVC960804CNBA so the door reliably actuates the switch when closed. Generic switches may not align with the door, leaving the furnace unable to start or unsafe to service. OEM fitment is recommended.
Shut off power at the breaker, transfer the wire connections to the new switch, and secure it to the mounting bracket in the same position. Confirm the door fully depresses the plunger when closed. Estimated time: 15–20 minutes.
Verify your model and serial number before ordering.
