E1 error on display and unit runs continuously or does not reach set temperature

Safety: Disconnect the wine cooler from power before accessing internal components.

• Access the evaporator area: Remove the interior rear panel inside the wine cooler compartment. This usually requires removing shelves and a few screws.
• Locate the evaporator NTC: It is typically clipped or taped directly to the evaporator coil or embedded in a small plastic housing attached to the coil.
• Check mounting: Ensure the sensor is firmly attached to the evaporator surface. A loose sensor can cause incorrect readings and trigger E1.
• Inspect wiring and connector: Look for corrosion, broken insulation, or loose plugs. Reseat the connector at both the sensor and the main PCB.
• Measure resistance: At room temperature (unit off and door open for a while), measure the sensor resistance. Compare to the cabinet NTC if they are the same part number. Replace the sensor if it is open, shorted, or significantly different from spec.
• Replace sensor: Install a new Beko evaporator NTC sensor if faulty. Secure it tightly to the evaporator coil for accurate temperature sensing.
• Control board check: If the sensor is good but E1 persists, the sensor input on the main control board may be defective and the board may need replacement.
