How to Fix / Troubleshooting
Safety: Disconnect from mains before opening the cabinet.
- Power reset: Unplug the Amica microwave for at least 10 minutes to allow the control electronics to fully discharge. Plug back in and test.
- Inspect control connections: Remove the outer cover and control panel. Check the ribbon cable between the display/touch panel and the main control PCB. Reseat connectors carefully.
- Check for visible damage: Look for burnt components, cracked solder joints, or bulging capacitors on the control board.
- Surge protection: If the error appeared after a lightning storm or power surge, the control PCB may be permanently damaged and require replacement.
- Replace control PCB: If wiring is intact and E05 persists, replace the main control board with the exact Amica part number. Transfer any configuration jumpers as per service documentation.
