Freezer compartment not reaching set temperature; error E2 displayed on Vestfrost refrigerator.

Safety warning: Always unplug the refrigerator before removing panels or testing components.

Steps to diagnose and fix E2 (freezer sensor):

• Confirm the error: Power-cycle the unit. If E2 reappears after a short run time, proceed.
• Access the freezer sensor: Remove freezer drawers and the rear inner panel (evaporator cover). The freezer NTC sensor is usually clipped to the evaporator tubing or mounted on the rear wall behind the cover.
• Visual inspection: Check for ice buildup around the sensor, broken clips, or damaged insulation. Ensure the sensor is firmly attached where designed.
• Test the NTC sensor: Disconnect the sensor from its connector. Measure resistance at freezer temperature (or at room temperature if removed and warmed). Compare to expected NTC values (commonly several kΩ at room temperature). Replace if open, shorted, or far out of spec.
• Check wiring harness: Inspect the harness where it passes through the cabinet for pinched or broken wires. Use a multimeter to verify continuity from the sensor connector to the main PCB.
• Replace faulty parts: Install a new Vestfrost freezer NTC sensor if defective. Route wiring as original to avoid contact with sharp metal or moving parts.
• Control board evaluation: If sensor and wiring are good but E2 persists, the main control board may be faulty. This typically requires professional diagnosis and replacement.

Note: After replacement, allow 12–24 hours for the freezer to stabilize at the correct temperature.
