Safety: Unplug before cleaning or accessing internal components.

Steps to improve dehumidification:

Check operating conditions: Ensure room temperature and humidity are within the unit’s effective range. Very low humidity or low temperature reduces water collection.
Clean filter and coils: Wash the air filter. Remove panels and gently clean dust from the evaporator and condenser coils with a soft brush and vacuum.
Verify fan operation: Confirm the fan runs at normal speed and airflow is strong at the exhaust. If weak, inspect and replace the fan motor assembly if needed.
Check for frost or uneven cooling: After running 10–15 minutes, inspect the evaporator coil. If only a small section gets cold or frosts, or if there is oil residue on tubing, the unit may have a refrigerant leak.
Professional service: Refrigerant issues and compressor failures require a certified technician. If cleaning and fan checks do not restore performance, contact Pro Breeze support or a refrigeration professional.

Dehumidifier runs but does not collect water; humidity in room does not decrease.
