How to Fix / Troubleshooting
Safety First: Unplug the unit before removing the control panel.
Steps to address E12:
- Power reset: Unplug the ice maker for 10 minutes, then plug back in to see if the error clears.
- Access control panel: Remove screws securing the front control panel or top cover to expose the keypad and ribbon cable.
- Inspect connections: Reseat the ribbon cable or wiring harness between the control panel and main control board. Ensure connectors are fully seated and not corroded.
- Check for moisture: Look for signs of condensation or water damage on the control panel. Dry gently with a soft cloth; do not use heat guns.
- Replace control panel: If buttons remain unresponsive or E12 persists, replace the Koldfront-compatible user interface/control panel assembly.
- Reassemble and test: Reinstall covers, restore power, and verify all buttons function and the error is cleared.
