Wine cooler shows E2 and the unit may overcool, undercool, or cycle erratically.

Safety warning: Disconnect power before removing rear or interior panels. Sharp metal edges can cause injury; wear cut-resistant gloves.

Steps:

• 1. Confirm the error: Note whether E2 appears immediately at power-on or only after running for a while. Persistent E2 usually indicates a sensor or wiring fault.
• 2. Access the evaporator area: Remove interior shelves and the rear interior panel inside the cooled compartment. The evaporator coil and its sensor will be behind this panel.
• 3. Locate the evaporator thermistor: It is typically clipped to the evaporator tubing or embedded in a small plastic holder attached to the coil, with two wires leading to the control board.
• 4. Inspect placement and condition: Ensure the sensor is firmly attached to the coil and not hanging loose. Check for ice buildup that may have pulled the sensor away or damaged the wires.
• 5. Electrical test: With the unit unplugged, disconnect the sensor from the control board and measure resistance with a multimeter. Compare the reading to the expected NTC value at the current temperature (often 5k–10k ohms at 77°F / 25°C). Replace the sensor if it reads open, shorted, or far out of range.
• 6. Replace if needed: Install a new evaporator temperature sensor compatible with your Kalamera model. Clip it securely to the evaporator coil in the same location as the original to ensure accurate defrost and cooling control.
• 7. Reassemble and test: Reinstall the interior panel and shelves. Restore power and verify that the E2 code clears and that the unit cools normally.

Note: If the sensor and wiring test good, the control board may not be interpreting the sensor signal correctly and may require replacement.
