How to Fix / Troubleshooting
Safety warning: Do not chip ice off the coil with sharp objects; this can puncture the refrigerant tubes.
- Step 1 – Turn off COOL mode: Switch the unit to FAN-only mode to melt the ice. Place towels under the unit to catch dripping water.
- Step 2 – Clean filters and coil: After ice melts, clean the filters and evaporator coil thoroughly.
- Step 3 – Check fan speed: Use medium or high fan speed in very humid conditions to maintain airflow.
- Step 4 – Inspect for airflow obstructions: Ensure furniture or curtains are not blocking the indoor unit intake or discharge.
- Step 5 – Technician tasks: If icing recurs, a technician should check refrigerant charge and the evaporator temperature sensor.
