Display shows E8; refrigerator may not respond correctly to temperature adjustments or may cool excessively.

Safety: Disconnect power before accessing any sensor wiring. Avoid damaging cabinet insulation when locating sensors.

Procedure:

• 1. Identify ambient sensor location: On many Hansa models, the ambient sensor is located near the front control panel or behind a small grille on the top or rear of the cabinet.
• 2. Access the sensor: Remove the control panel cover or grille as needed. Carefully pull out the sensor probe and connector.
• 3. Visual check: Inspect the sensor for physical damage or corrosion at the connector.
• 4. Measure resistance: Disconnect the sensor and measure its resistance at room temperature. Compare to typical NTC values. If the reading is open or shorted, the sensor is faulty.
• 5. Check wiring: If the sensor tests OK, check continuity from the sensor connector to the main control board. Repair any breaks or shorts.
• 6. Replace faulty parts: Install a new ambient temperature NTC sensor if needed. If wiring and sensor are good but E8 persists, the main control board may require replacement.

Note: An incorrect ambient reading can cause the refrigerator to overcool or undercool, so resolving E8 is important for proper operation.
