IceKing ice maker powers on but buttons do not respond or respond intermittently.

Safety first: Unplug the unit before removing the control panel.

Step-by-step checks:

• 1. Dry the panel: If the panel was recently cleaned, allow it to dry completely. Avoid spraying cleaner directly on the controls.
• 2. Reseat ribbon cable: Remove the front panel and reseat the ribbon cable between the user interface and main board.
• 3. Inspect for damage: Look for cracks or corrosion on the user interface PCB. Replace if damaged.
• 4. Test operation: Reassemble and test each button. If some buttons still fail, replace the entire control panel assembly.

When to call a technician: If both the interface and main board may be involved, professional diagnosis is recommended.
