Soleus Air Poor Dehumidification Performance

Unit runs in dehumidify (DRY) mode but produces very little water and room remains humid.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Room too large for unit capacity, Low refrigerant charge, Evaporator coil partially frozen, Incorrect fan speed setting

Safety: Turn off and unplug before cleaning or inspection.

Check capacity: Confirm that the Soleus Air unit's BTU rating is appropriate for the room size and humidity level.
Clean filters and coils: Dirty coils reduce moisture removal. Clean as described earlier.
Use lower fan speed: In DRY mode, a lower fan speed can increase dehumidification by allowing more contact time with the coil.
Professional check: If performance remains poor, a refrigerant or compressor issue may be present and should be evaluated by a technician.
