The display works, but buttons do not respond; the unit is stuck in one mode.

Safety first: Unplug the unit if you need to remove the control panel.

• Disable control lock: Check the user manual for a control lock or child lock function (often activated by holding a specific button for several seconds). Try unlocking.
• Power reset: Unplug the ice maker for 5–10 minutes, then plug it back in to reset the electronics.
• Dry keypad: If the issue started after cleaning, allow the panel to dry thoroughly. Avoid spraying cleaner directly on the panel in the future.
• Replace UI module: If buttons remain unresponsive, replace the user interface/keypad assembly.
