Possible Causes

Dirty air filter, blocked evaporator coil, indoor fan not running properly, low refrigerant charge, very low room temperature

How to Fix / Troubleshooting

Safety: Turn off the unit and allow ice to melt before working on it. Place towels to catch water.

Steps:

  • Defrost: Turn the unit off or set to Fan mode only until all ice has melted.
  • Clean filters and coil: Thoroughly clean the air filter and evaporator coil to restore airflow.
  • Check fan operation: Ensure the indoor fan runs at all speeds. If slow or intermittent, inspect and replace the fan motor or capacitor.
  • Temperature setting: Avoid setting the temperature extremely low in cool environments; keep room temperature above ~18°C.

If icing recurs with clean filters and good airflow, the refrigerant charge may be incorrect and should be checked by a technician.
