Possible Causes
Low room temperature, Restricted airflow from dirty filter, Low refrigerant charge, Faulty evaporator temperature sensor not initiating defrost
How to Fix / Troubleshooting
Safety: Unplug the unit and allow ice to melt before further inspection.
Steps to prevent icing:
- Operate in proper temperature range: Use the dehumidifier only in rooms above the minimum specified temperature.
- Clean filter and grilles: Wash the filter and clear dust from intake and exhaust.
- Check fan operation: Ensure the fan runs at full speed; a weak fan can cause icing.
- Inspect evaporator sensor: Verify the sensor is attached correctly to the coil. Replace the evaporator temperature sensor if it is loose or defective.
- Professional service: If icing persists with good airflow and correct sensor operation, the sealed system may be undercharged and needs a technician.
