Wine Enthusiast wine cooler shows E2 and may run continuously or not cool properly.

Safety: Unplug the cooler before opening any panels. Sharp metal edges may be present around the evaporator cover.

• Access the evaporator area: Remove the interior rear panel inside the cabinet (often held by Phillips screws) to expose the evaporator coil on compressor-based Wine Enthusiast models. On some thermoelectric models, the sensor is mounted near the aluminum heat sink.
• Inspect sensor placement: The evaporator sensor is usually clipped or taped to the evaporator tubing. Ensure it is firmly attached and not hanging loose. Reattach with aluminum tape or the original clip if necessary.
• Check for ice damage: Look for heavy ice buildup that may have pulled or broken the sensor wire. If ice is present, allow the unit to fully defrost (doors open, unit unplugged) for several hours before proceeding.
• Test the sensor: Disconnect the sensor from the control board and measure resistance with a multimeter. Compare to the cabinet sensor values at similar temperatures. A reading of OL (open) or 0 ohms indicates a failed sensor.
• Replace the evaporator sensor: If faulty, install a compatible Wine Enthusiast evaporator temperature sensor. Route the wire away from sharp fins and secure it to the coil where the original sensor was located.
• Reconnect and test: Reassemble the interior panel, plug the unit back in, and verify that the E2 code clears and the unit cycles normally.

If the E2 error remains after sensor replacement, the main control board may not be reading the sensor correctly and may require replacement.
