Display shows E2 and unit may run continuously or shut down erratically.

Safety: Disconnect power before accessing internal components. Sharp metal edges near the evaporator can cause injury; wear cut-resistant gloves.

• Defrost the unit: Power off and leave the door open for several hours to melt any heavy ice on the evaporator. Place towels to catch water.
• Access evaporator area: Remove the interior rear panel inside the wine cooler (usually held by Phillips screws) to expose the evaporator coil and sensor.
• Locate the sensor: The evaporator sensor is typically clipped to the evaporator tubing or mounted in a small well near the coil with two wires leading to the control board.
• Inspect for damage: Look for broken insulation, corrosion, or a sensor that has come loose from the coil. Ensure the sensor is firmly attached to the evaporator surface.
• Test and replace: Disconnect the sensor and measure resistance. If it reads open, shorted, or far outside the expected range, replace it with a Kismile evaporator temperature sensor (NTC). Clip or tape the new sensor securely to the coil as originally installed.
• Reconnect and test: Reassemble the rear panel, restore power, and verify that the E2 code clears. If not, the main control board may need replacement.
