How to Fix / Troubleshooting
Safety first: Unplug the ice maker before removing the control panel.
Steps to resolve E11:
- Dry the panel: If the panel is wet from spills or condensation, unplug the unit and allow it to dry completely for several hours.
- Inspect the keypad: Remove the front/top bezel to access the keypad or display PCB. Look for corrosion or moisture marks.
- Check ribbon cable: Reseat the ribbon cable between the keypad and main control board. Ensure it is not kinked or torn.
- Test buttons: If accessible, use a multimeter to check continuity across button contacts when pressed.
- Replace if defective: Install a new Tristar user interface / keypad assembly if buttons are unresponsive or the PCB is damaged.
