Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the microwave before removing the control panel or touching internal wiring.
Steps:
- 1. Power reset: Disconnect power for 5–10 minutes to allow the control board to reset. Plug back in and test.
- 2. Check for moisture: If E05 appeared after heavy steam cooking, open the door and let the unit dry for several hours. Wipe the control panel surface dry.
- 3. Inspect ribbon cable (for DIYers): Remove the control panel assembly (usually held by a few screws and clips). Carefully disconnect and reconnect the flat ribbon cable between the touchpad and the main PCB. Ensure it is fully seated and not corroded.
- 4. Visual inspection: Look for burn marks or corrosion on the control board. If present, the board likely needs replacement.
Resolution: If reseating the ribbon cable and drying the panel does not clear E05, replace the touch control panel or the main control PCB with the correct IKEA-compatible part, following the service manual.
