Kenmore Oven Error Code F15

F15 means the oven's controller self-check has failed. Either the User Interface Board or the Appliance Control Board detected a problem with its own internal circuitry during a diagnostic routine. The oven displays this code to indicate that one of its core control boards is not functioning correctly and requires attention.

It is not recommended to continue using the oven while the F15 code is active. The fault indicates an internal control board failure, which means oven functions may not operate as intended, including safety controls. Discontinue use until the faulty board has been diagnosed and replaced.

Repair costs vary depending on which board requires replacement and whether you hire a technician or complete the repair yourself. User Interface Boards and Appliance Control Boards for Kenmore ovens typically range from $50 to $250 or more for parts alone, depending on the model. Adding professional labor can bring the total cost to between $150 and $400 or higher.

The first recommended step is replacing the User Interface Board, which is a repair some experienced DIYers can perform if they are comfortable working with appliance electronics. If that does not resolve the issue, the Appliance Control Board may also need replacement. Sourcing the correct replacement board for your specific Kenmore model is important before attempting the repair.

Cutting power to the oven at the circuit breaker for several minutes can sometimes clear a temporary or firmware-related fault. However, if the User Interface Board or Appliance Control Board has suffered actual internal circuit damage, the F15 code will return after power is restored. A reset is worth attempting as a first step but is not a permanent fix for a hardware failure.
