How to Fix / Troubleshooting
Safety: Unplug the microwave before any inspection.
- Power cycle: Unplug for 5–10 minutes to reset the electronics, then plug back in and test.
- Check for moisture: If steam has entered the control area (e.g., from cooking on a hob below), allow the unit to dry for several hours with the door open.
- External cleaning only: Wipe the keypad surface with a slightly damp cloth and dry. Do not use excessive liquid.
- Service: If E07 remains, the keypad membrane or control PCB likely needs replacement. This involves removing the control panel assembly and should be done by a qualified technician.
