Display shows E2 and the unit may run continuously or not cool correctly.

Safety first: Disconnect the wine cooler from power before opening any panels. Beware of sharp metal edges around the evaporator area.

Steps to check and fix:

• 1. Defrost the unit: If there is heavy ice buildup on the back wall, switch off and leave the door open for several hours or use a fan to speed up defrosting. Do not use sharp tools to chip ice.
• 2. Access the evaporator: Remove the internal rear panel inside the compartment to expose the evaporator coil and fan assembly. The evaporator NTC is usually clipped directly to the coil or inserted into a small well on the evaporator plate.
• 3. Inspect the sensor: Check that the sensor is firmly attached to the evaporator and not dangling. Look for cracked insulation or broken wires, especially where they pass through the foam insulation.
• 4. Test the NTC: With the unit unplugged, disconnect the sensor from the main PCB and measure resistance with a multimeter. Compare to expected values (for many Vestfrost NTCs, around 5–10 kΩ at room temperature). If the reading is open or shorted, replace the sensor.
• 5. Replace the evaporator sensor: Unclip the old sensor, carefully pull the wiring through the grommet, and route the new sensor along the same path. Ensure it has good thermal contact with the evaporator coil and is not touching the fan blades.
• 6. Reassemble and test: Refit the rear panel, restore power, and monitor operation. The E2 code should clear once the control board detects a valid sensor signal.
• 7. If E2 remains: If a new sensor does not resolve the error, the main control PCB may be defective and should be evaluated or replaced by a technician.
