Safety first: Unplug the wine cooler before removing the control panel or upper grille. Avoid static discharge to electronic boards.

Steps to troubleshoot:

1. Power reset: Disconnect power for 5–10 minutes, then restore. If E10 reappears and buttons are unresponsive, continue.
2. Access the control panel: Remove the upper grille or trim to expose the user interface (UI) board and its ribbon cable to the main control board.
3. Inspect connections: Carefully disconnect and reconnect the ribbon cable and any harnesses between the UI and main board. Ensure connectors are fully seated and not corroded.
4. Check for moisture or damage: Look for condensation, liquid spills, or corrosion on the UI board. If present, the panel may need replacement.
5. Test button response: After reassembly and restoring power, test all buttons. If some or all remain unresponsive and E10 persists, the UI board is likely defective.
6. Replace UI or main board: Replace the touch control panel if it shows signs of failure. If a new UI does not resolve the issue, the main control board may be at fault and should be replaced by a technician.

Note: Handle ribbon cables gently to avoid tearing. Do not bend them sharply.

Wine cooler displays E10 and the unit may not respond to temperature adjustments.
