Display shows E04; ice production stops and the evaporator plate may be heavily iced over.

Safety first: Unplug the ice maker before accessing internal components. Sharp metal edges may be present.

• Locate the evaporator sensor: Remove the front or side panel to access the evaporator plate. The NTC sensor is usually clipped or glued to the evaporator surface.
• Check the connection: Ensure the sensor plug is fully seated on the control board and at the sensor end. Clean any corrosion with contact cleaner.
• Inspect the cable: Look for pinched or cut wires along the route from the evaporator to the PCB.
• Measure sensor resistance: With the unit at room temperature, disconnect the sensor and measure resistance with a multimeter. Typical NTC values are 5–20 kΩ at 25°C (refer to Candy specs). If the reading is open, shorted, or far from spec, replace the sensor.
• Check for board issues: If a known-good sensor still triggers E04, the control board’s sensor input may be defective and the PCB will need replacement.
• Reattach sensor properly: Ensure the new or existing sensor is firmly in contact with the evaporator surface using the original clip or thermal paste if provided.
