Safety first: Disconnect the appliance from mains before accessing internal components.

Locate evaporator sensor: Remove the interior ice bin and front cover to access the evaporator plate. The NTC sensor is usually clipped or bonded to the evaporator surface.
Inspect sensor and wiring: Look for broken insulation, pulled wires, or corrosion at the sensor connector.
Test sensor resistance: Disconnect the sensor from the harness and measure resistance with a multimeter at room temperature. Compare to Gorenje's NTC resistance chart. A reading of 0 Ω (short) or infinite (open) indicates failure.
Check continuity to PCB: If the sensor tests good, check continuity from the sensor connector to the main control board plug to rule out harness damage.
Replace faulty NTC: Install a new evaporator temperature sensor of the correct value. Secure it firmly to the evaporator with the original clip or thermal paste as required.
Reset power: Reassemble, restore power, and clear the error by cycling power. Monitor a full ice-making cycle.

Display shows E4 and the unit stops making ice; fan may run but ice tray remains warm.
