Possible Causes

Dirty air filter on TCL indoor unit, Indoor fan not running at full speed, Low refrigerant charge, Operating at very low indoor temperature setting

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.
