Door not detected as closed, Child lock enabled, Faulty start button on control panel, Internal control logic fault
How to Fix / Troubleshooting
Safety first: Ensure the oven is off and cool while inspecting controls.
- Check for child lock: Look for a key symbol or lock icon. Press and hold the corresponding button for several seconds to disable.
- Verify door switch: Open and close the door while listening for a click from the door switch. Test the switch electrically if accessible.
- Test start button: If using a physical button, ensure it clicks and is not stuck. For touch panels, clean the surface and try again.
- Control reset: Turn off power at the breaker for 10 minutes to reset the control. If the issue persists, the user interface or main control board may be faulty.
