Possible Causes

Clogged air filters, Dirty indoor coil, Indoor fan running too slowly or not at all, Low refrigerant charge

How to Fix / Troubleshooting

Safety first: Turn off the unit and allow ice to melt naturally; do not chip ice with sharp objects.

  • Clean filters and coil: Restore airflow by thoroughly cleaning filters and the evaporator coil.
  • Check fan speed: Ensure the indoor fan responds to speed changes and delivers strong airflow.
  • Avoid very low setpoints: Do not set the thermostat excessively low in cool mode, especially in humid conditions.
  • Call technician if recurring: If icing returns after cleaning, have a professional check refrigerant charge and system pressures.

Prolonged operation with ice can damage the compressor and cause water leaks when thawing.
