Possible Causes
Child lock feature enabled, Faulty touch panel, Loose ribbon cable, Control board not responding to UI
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before removing the control panel.
Steps:
- Check lock status: Look for a lock icon on the display. Disable child lock by pressing and holding the designated button combination (often 3–5 seconds; see user manual).
- Power reset: Unplug for 5 minutes and reconnect to clear temporary glitches.
- Inspect UI connections: Remove the display panel and ensure the ribbon cable is fully seated and undamaged.
- Replace UI board: If buttons remain unresponsive and wiring is intact, replace the user interface board.
Note: If a new UI does not resolve the issue, the main control board may be faulty.
