Wine cooler shows E6 and may not respond correctly to temperature settings.

Safety: Disconnect power before removing the control panel or rear cover.

How to troubleshoot E6:

• Power cycle: Unplug the unit for 10 minutes, then plug back in. If E6 reappears immediately, continue.
• Access the control panel: Remove the screws securing the front control panel or door trim (depending on model). Carefully pull the panel forward to expose the display PCB and wiring.
• Inspect ribbon cable/harness: Look for a flat ribbon cable or multi-wire harness running from the display PCB to the main control board. Check for kinks, cuts, or loose connectors.
• Reseat connectors: Gently unplug and replug the connectors at both ends to clean contacts. Ensure they are fully seated and locked.
• Check for moisture: If there are signs of condensation or liquid intrusion around the control panel, dry the area thoroughly and consider adding a moisture barrier if appropriate.
• Board replacement: If wiring is intact and E6 persists, either the display PCB or main control board may be defective. Replace the display PCB first (usually easier and cheaper), then the main board if needed.

Note: Handle PCBs by the edges and avoid static discharge. If you are not comfortable working with electronics, contact a qualified technician.
