Possible Causes
Loose harness between clock/timer board and main control, Failed clock/timer module, Faulty main control board, Oxidized connectors at control interface
How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker before accessing internal controls.
Steps to check and correct:
- Access control area: Remove the back cover or front bezel to expose the clock/timer module and main control board.
- Inspect harness: Locate the multi-pin harness connecting the clock/timer to the main control. Disconnect and reconnect it to clean the contacts. Look for bent pins or corrosion.
- Check for damage: Examine both boards for signs of burning, cracked solder joints, or moisture damage.
- Test operation: Restore power and test timer and bake functions. If F11 returns, one of the boards is likely defective.
- Replace faulty module: Start by replacing the clock/timer module if it is separate. If the issue persists, the main control board may also need replacement.
When to call a technician: Board-level diagnostics and replacement are best handled by a trained technician.
