E8 displayed, freezer may not defrost properly or may show irregular frost patterns on the evaporator.

Safety: Disconnect mains power before accessing internal components.

What to do:

• 1. Verify recent repairs: If a sensor was recently replaced, confirm that the correct Amica part number was used and that it is installed in the original position on the evaporator.
• 2. Access evaporator area: Remove the internal rear panel to expose the evaporator and defrost sensor. Ensure the sensor is firmly clipped to the coil and not hanging loose.
• 3. Check connections: Inspect the sensor connector for loose pins or poor crimping. Reseat the plug and ensure no extra splices or extensions have been added that could alter resistance.
• 4. Compare resistance: Measure sensor resistance at a known temperature (e.g., room temperature or in ice water) and compare with manufacturer data if available. Replace with a genuine "Amica Defrost NTC Sensor" if readings are out of range.
• 5. Clear error: After correcting the issue, unplug the freezer for several minutes to reset the control, then restore power and monitor for recurrence.

Note: Persistent E8 with correct sensors and wiring may indicate a faulty main control board.
