Possible Causes
Faulty function selector switch, broken knob shaft, failed low-voltage supply on control board, defective door switch (on some models)
How to Fix / Troubleshooting
Safety first: Disconnect power before removing the control panel.
- Check display and timer: Ensure the clock is set and no child lock is active; many AEG ovens will not start without a set time.
- Test selector: Rotate the function knob; if the display does not change or feels loose, inspect the selector and knob.
- Door switch: On models with a door switch, ensure it is actuated when the door closes. Test continuity and replace if faulty.
- Selector replacement: If the selector does not send signals to the board, replace it with the correct AEG part.
Warning: Incorrectly refitting the control panel can trap wires and cause shorts; route harnesses carefully.
