Possible Causes
Dirty air filter restricting airflow, Fan motor running too slowly or failing, Low refrigerant charge, Thermistor misreading coil temperature
How to Fix / Troubleshooting
Safety: Unplug the unit and allow ice to melt completely before further inspection.
Steps:
- Clean filter and coil: Ensure both are clean to maximize airflow.
- Check fan operation: Confirm the indoor blower runs at full speed on HIGH. If slow or intermittent, replace the blower motor or capacitor.
- Thermostat setting: Avoid setting the temperature extremely low in cool, humid conditions; moderate settings reduce icing.
- Sensor check: Inspect and test the evaporator thermistor. Replace if out of spec.
- Professional service: If icing persists, a technician should check refrigerant charge and system pressures.
