Error E02 displayed; freezer temperature reading is incorrect or shows error, freezer may overcool or not cool properly.

Safety first: Unplug the refrigerator before removing freezer panels. Wear cut-resistant gloves when working around sharp metal edges.

Step 1 – Access the freezer NTC sensor:

• Remove drawers and the rear interior panel of the freezer to expose the evaporator area.
• Locate the NTC sensor clipped to the evaporator tubing or mounted on the wall.

Step 2 – Visual inspection:

• Check for ice buildup around the sensor; gently remove ice with warm air, not sharp tools.
• Inspect the connector and wiring for damage or corrosion.

Step 3 – Electrical test:

• Measure resistance of the sensor at a known temperature and compare to the Fhiaba chart.
• Replace the sensor if readings are out of range or unstable when gently moved.

Step 4 – Reassemble and test:

• Secure the new sensor in the same position and route the harness away from moving parts or sharp edges.
• Restore power, clear E02, and monitor freezer temperature over 24 hours.
• If E02 persists, the main control board may require replacement.
