Kenmore Range Error Code F26

F26 on a Kenmore range indicates a communication failure between the main Electronic Oven Control board and the Mini Oven Control Board. This fault only appears on models equipped with the Bake-n-Warm feature. The error means the two boards have lost contact, which prevents safe operation of the Bake-n-Warm system. The most common causes are a loose wiring harness or a missing 15VDC supply to the Mini Oven Control Board.

The F26 code specifically affects the Bake-n-Warm secondary oven system. The main oven and cooktop may still function depending on how the range responds to the fault, but operating an appliance with an active control board communication error is not recommended without diagnosing the cause first. Have the issue inspected before continuing regular use.

Repair costs vary depending on which component has failed. If only a wiring harness repair is needed, costs are generally lower, typically in the range of $75 to $150 for a service call. A Mini Oven Control Board replacement usually runs between $100 and $250 for the part, plus labor. Replacing the EOC board tends to be more expensive, often ranging from $150 to $400 or more for the part depending on the model, plus labor costs.

You may be able to clear F26 temporarily by disconnecting the range from power for several minutes and then restoring power. However, if the underlying wiring or component issue is not resolved, the code will return. A reset alone does not fix a loose connector, wiring fault, or failed control board, so the root cause should be diagnosed and corrected.

Start by checking the wiring harness and connectors running from the EOC to the Mini Oven Control Board, ensuring all connections are secure and free of corrosion. Next, use a multimeter to verify 15VDC is present on the red and gray wires at the Mini Oven Control Board connector. If the harness and voltage are good, replace the Mini Oven Control Board. If the fault returns after that replacement, the EOC will need to be replaced.
