Frigidaire Range Error Code F26

F26 indicates a communication failure between the main Electronic Oven Control board and the Mini Oven Control Board that manages the Bake-n-Warm drawer. This code only appears on Frigidaire models that include the Bake-n-Warm feature. The main oven cavity may still function, but the Bake-n-Warm drawer will not operate while this fault is active. Diagnosis involves checking the wiring harness and confirming 15VDC is reaching the Mini Oven Control Board.

The F26 fault is specific to the Bake-n-Warm drawer communication circuit and does not necessarily affect the main oven or cooktop operation. That said, you should avoid using the Bake-n-Warm feature until the fault is resolved. If the range is displaying the error continuously and behaving abnormally in other ways, discontinue use and have it serviced.

If only the harness or a connector needs repair, costs are typically low, covering minimal parts and labor. Replacing the Mini Oven Control Board generally costs somewhere in the range of $100 to $250 depending on the specific model and labor rates in your area. If the EOC also requires replacement, total repair costs can rise to $200 to $450 or more. Getting a firm estimate from a technician after diagnosis is the best approach.

A knowledgeable DIYer can start by inspecting the wiring harness and connectors between the EOC and the Mini Oven Control Board for visible damage, loose pins, or corrosion. Confirming the 15VDC supply on the red and gray wires with a multimeter is also a straightforward check. However, if a control board replacement is required, comfort with appliance electronics and safe isolation of power is necessary before proceeding.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the F26 code, but it will return if the underlying wiring or board fault is still present. A reset is useful for confirming whether the fault is intermittent or persistent, but it is not a repair. The root cause must be addressed to permanently resolve the error.
