Wine Enthusiast wine cooler interior is freezing bottles or forming ice on the back wall.

Safety: Unplug the unit before accessing sensors or the control board.

• Check temperature setting: Ensure the setpoint is not at the lowest possible value. Adjust to a typical wine storage temperature (e.g., 55°F / 13°C).
• Redistribute bottles: Avoid placing bottles directly against the rear wall where the evaporator is located. Leave space for air circulation.
• Inspect sensor placement: Verify the cabinet sensor is properly mounted away from the evaporator coil and not touching cold metal surfaces.
• Test sensor: Measure resistance of the cabinet sensor at known temperature. Replace if readings are out of specification.
• Check compressor cycling: If the compressor runs nearly constantly regardless of setpoint, the control board relay may be stuck. Replace the main control board if confirmed.

After corrections, allow 24 hours for temperatures to stabilize and confirm that freezing no longer occurs.
