Kenmore Range Error Code F15

The F15 error code on a Kenmore range indicates that the Electronic Oven Control (EOC) has detected a failure during its internal self-check routine. The EOC is the main control board that manages all oven and cooktop functions, including temperature regulation, keypad input processing, and safety relay operation. During power-up or normal operation, the EOC runs a self-diagnostic sequence to verify that its internal memory, processor, and circuit pathways are functioning correctly. When this self-check fails, the board flags F15 and typically locks out oven operation to prevent unsafe or unpredictable behavior.

The most common root cause of F15 is an internal failure within the EOC itself. This can include corrupted firmware, a failed processor, damaged memory components, or degraded solder joints on the board. Power surges and voltage spikes are frequent contributors, as they can damage sensitive microprocessor circuits without leaving any visible burn marks. In some cases, a loose or corroded wiring harness connection between the EOC and related components can trigger a false self-check failure, though this is less common than an outright board failure.

Because the F15 code points directly to the EOC's self-check routine rather than an external sensor or peripheral component, the diagnostic path is straightforward. The first recommended step is replacement of the EOC. Before replacing the board, it is worth inspecting all wiring harness connectors at the EOC for corrosion, looseness, or heat damage. If connections are clean and secure and the error persists after a power reset, the EOC itself is the likely failed component and should be replaced.
