Display shows E0 and the temperature cannot be adjusted or saved

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

Steps to check and correct:

• Power reset: Unplug the unit for 5 minutes, then plug it back in. Try adjusting the temperature again. If E0 returns, continue.
• Access the control panel: Remove the top/front trim screws (usually inside the door frame) and gently pull the display/control panel forward.
• Inspect wiring: Locate the low‑voltage harness or flat ribbon cable running from the display PCB to the main control board. Check for loose plugs, bent pins, or corrosion. Reseat each connector firmly.
• Check for moisture damage: Look for signs of condensation or liquid on the display PCB. If present, dry carefully with a clean cloth and allow the board to air‑dry for at least 30 minutes before reassembly.
• Reassemble and test: Refit the panel, restore power, and test all buttons. If the error persists, the touch control PCB is likely defective and should be replaced.

When to stop: If you see burnt components or melted plastic on the board, do not continue using the cooler. Replace the control panel or contact a qualified technician.
