Ice maker powers on but buttons or touch controls do not respond.

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

Steps to restore control:

• Check for lock mode: Some Haier models have a control lock. Refer to the user manual to unlock (often by holding a specific button for several seconds).
• Power reset: Unplug the unit for 5–10 minutes, then plug back in and test buttons.
• Inspect connections: Remove the control panel and check the ribbon cable or harness between the panel and main board. Reseat firmly.
• Check for moisture: Look for signs of water ingress behind the panel. Dry thoroughly if present.
• Replace UI board: If buttons remain unresponsive, replace the user interface/control panel assembly.

When to call a technician: If a new panel does not resolve the issue, the main control board may be faulty and should be checked professionally.
