How to Fix / Troubleshooting
Safety: Unplug the unit before accessing the control board.
Steps:
- 1. Power reset: Unplug the ice maker for at least 10 minutes to allow the control board to fully discharge. Plug back in and see if E12 clears.
- 2. Check power quality: Plug the unit into a properly grounded outlet. Avoid extension cords or power strips. Consider using a surge protector.
- 3. Inspect control board connections: Remove the control panel or rear access cover to reach the main PCB. Reseat all harness connectors firmly.
- 4. Look for damage: Examine the board for burn marks, swollen components, or corrosion. If present, the board must be replaced.
- 5. Replace control board: If E12 persists after reset and inspection, install a new Avanti-compatible main control board.
