Why is my Gree GCF220BKNA not humidifying?
- MMrs. Tara WongAug 9, 2025
Your Gree Air Cleaner might not be humidifying for several reasons. The unit may not humidify when the water tank is full. Water will naturally evaporate when the unit isn't operating. The humidifying operation will stop automatically when the room humidity is too high under auto humidify mode. Ensure the ON/OFF indicator light is on; if not, press the "ON/OFF" button. Also, check if the filter is correctly assembled and free of dirt or scale. If the water lacking indicator light is on, correctly assemble the water tray. Finally, confirm that the set humidity is 10% higher than the ambient humidity.
