How to Fix / Troubleshooting
Safety first: Turn OFF the unit and allow ice to melt completely before further operation.
- Step 1 – Clean filters: Wash and dry filters thoroughly.
- Step 2 – Check fan operation: Run FAN mode and ensure strong airflow. Repair or replace the fan motor if weak.
- Step 3 – Adjust temperature: Avoid setting the thermostat too low (e.g., below 22–24°C in cooling).
- Step 4 – Refrigerant check: If icing recurs, have a technician check for low refrigerant or expansion device issues.
Warning: Do not chip ice off the coil; this can puncture refrigerant tubes.
