Unit frequently shuts off with ICE FULL even though ice is not blocking the sensor; intermittent operation.

Safety first: Unplug the unit before adjusting sensors.

Steps to stabilize ice level detection:

• Secure connectors: Access the ice full sensor wiring and ensure the connector is firmly seated on the control board.
• Reinforce mounting: Tighten any loose screws holding the sensor brackets. Add a small piece of foam or tape if needed to prevent vibration.
• Clean lenses: Wipe the sensor windows to ensure a clear beam path.
• Test with movement: Run the unit and gently tap the cabinet near the sensor. If ICE FULL triggers, the sensor may be failing.
• Replace sensor: Install a new ice full infrared sensor assembly if intermittent faults continue.

When to call a professional: If a new sensor does not resolve the issue, the control board may need replacement.
