Possible Causes
How to Fix / Troubleshooting
Safety: Always unplug the unit before removing panels or handling wiring.
Troubleshooting steps:
- Check room temperature: Ensure the ice maker is used within the specified ambient range (typically 50–90°F / 10–32°C). Extremely hot or cold rooms can trigger protection errors.
- Locate ambient sensor: The ambient thermistor is often mounted near the air intake grille or on the control board housing. Look for a small probe with two wires.
- Inspect mounting: Confirm the sensor is not touching hot components (compressor, condenser) and is exposed to room air.
- Check wiring: Follow the sensor wires to the control board. Make sure the connector is secure and wires are not damaged.
- Reset and test: After reseating the connector, reassemble, plug in, and restart. If E6 persists, the sensor or board is likely faulty.
Repair note: Replacing the ambient thermistor is usually straightforward once accessed. If a new sensor does not resolve E6, the main control board will need replacement by a technician.
