Display shows E0 and the temperature cannot be adjusted or the buttons do not respond properly.

Safety first: Unplug the Lanbopro wine cooler from the wall outlet before removing any panels. Do not work on live circuits.

• Power reset: Unplug the cooler for 5–10 minutes, then plug it back in. Check if the E0 code clears and if the buttons respond.
• Inspect control panel connections: Remove the top/front trim to access the display and keypad assembly. Verify the ribbon cable or wire harness from the display to the main control board is fully seated and not pinched or corroded.
• Check for moisture: Look for condensation or liquid inside the control panel area. If present, gently dry with a soft cloth and allow the unit to air dry for several hours before reassembly.
• Test keypad: With power disconnected, visually inspect the touchpad for cracks or delamination. If some buttons never respond even after reseating the harness, the touch control panel is likely defective and should be replaced.
• Replace components as needed: If wiring is intact and drying does not help, replace the touch control panel. If the issue persists, the main control board may also need replacement.
