Unit in DRY (dehumidify) mode produces very little water and does not seem to reduce humidity.

Safety first: Standard cleaning precautions apply; unplug before opening panels.

Steps:

• 1. Check room conditions: Dehumidify mode works best above ~65°F (18°C). At lower temperatures, water removal is limited.
• 2. Verify mode: Ensure the unit is actually in DRY mode and not just FAN mode.
• 3. Clean filter and coils: Improve airflow by cleaning the filter and evaporator coil.
• 4. Reduce room load: Close windows and doors to prevent humid outdoor air from entering.
• 5. Professional evaluation: If the unit cools poorly and removes little moisture even in COOL mode, the sealed system may be undercharged and should be checked by a technician.
