How to Fix / Troubleshooting
Safety: Unplug the unit and allow ice to melt completely before further use.
- Room temperature: Ensure the room is within the specified operating range. Move to a warmer area if needed.
- Clean airflow path: Wash the air filter and vacuum dust from the evaporator coil.
- Check fan operation: Confirm the fan runs at full speed and the fan motor is not weak.
- Sensor/charge issues: If icing continues, the defrost sensor or refrigerant charge may be at fault. Replace the evaporator temperature sensor if suspect, and call a technician for refrigerant diagnosis.
