Possible Causes
Room too cold for effective dehumidification, Dirty coils reducing heat exchange, Low refrigerant charge, Oversized unit short cycling
How to Fix / Troubleshooting
Safety: Unplug before cleaning.
- Check room temperature: Dehumidify mode is less effective below about 65°F (18°C). Use in warmer conditions if possible.
- Clean filter and coils: Ensure maximum airflow and heat exchange by cleaning the filter and both coils.
- Run continuously: Set the unit to continuous dehumidify and allow several hours of operation.
- Refrigerant diagnosis: If water removal remains minimal and coils are not getting cold, have a technician check for low refrigerant or compressor issues.
