How to Fix / Troubleshooting
Safety first: Disconnect power before accessing the control panel.
- Power reset: Turn off the oven at the breaker for 10–15 minutes, then restore power and attempt to set the clock again.
- Check mains supply: Ensure the oven is connected to a stable power source with correct voltage. Frequent brownouts or surges can disrupt the clock.
- Inspect control board: Remove the control panel and inspect the clock/control board for visible damage. If the clock section appears burnt or components are loose, replace the board.
When to call a technician: Persistent E11 usually requires control board replacement, which is best handled by a professional.
