Kenmore Range Error Code F12

F12 on a Kenmore range indicates an internal software error or failure within the Electronic Oven Control (EOC), which is the main control board. The board has detected a fault in its own internal logic or firmware. This is not a sensor or wiring issue but a problem originating inside the board itself. A power reset is the first step, and if the code returns, the EOC requires replacement.

It is not recommended to operate the oven while the F12 error is active. Because this fault indicates the main control board is not functioning correctly, the oven may not regulate temperature properly or respond to controls as expected. You should resolve the fault before resuming normal use to avoid potential safety issues or damage to food.

Replacing the EOC is a repair that technically capable DIYers can perform, as it generally involves disconnecting the wiring harness and mounting screws to remove the old board and install the new one. However, working near electrical components in a range carries risk, and the range must be fully disconnected from power before any work begins. If you are not comfortable working with appliance electronics, a qualified technician should handle the replacement. Always confirm the replacement part is correct for your specific model number.

A power reset will sometimes clear F12 if the cause was a temporary software glitch. Disconnect power to the range for at least 30 seconds, then restore it. If the F12 code does not return, the issue was transient and the range can be used normally. If F12 comes back immediately after power is restored, the EOC has a persistent failure and must be replaced.

If the EOC needs to be replaced, parts typically range from around $150 to $350 depending on the specific Kenmore model. Adding professional labor for the repair brings the total cost to roughly $250 to $500 or more. If the power reset resolves the issue, there is no cost at all. Getting a repair quote alongside the appliance's age can help determine whether replacement or repair is the better value.
