How to Fix / Troubleshooting
Safety first: Disconnect power before inspecting internal components.
Steps to handle Er/ERR:
- 1. Hard reset: Unplug the wine cooler for at least 10 minutes. Plug back in and observe if the error returns.
- 2. Check power source: Verify the outlet voltage with a multimeter (typically 110–120V AC in North America). Avoid using power strips or long extension cords.
- 3. Inspect control board: Remove the rear electronics cover and visually inspect the main PCB for burnt spots, cracked solder joints, or loose connectors.
- 4. Reseat all connectors: Disconnect and reconnect all harnesses to ensure good contact.
- 5. Replace control board: If the error persists and no specific sensor or component fault is found, replace the main control board with the correct Vinotemp part.
Note: Document the model and serial number before ordering a replacement board to ensure compatibility.
