Try this first!
Clean off any accumulated dust, lint, or other debris from the front and rear intake grills. This will restrict the airflow and may affect the unit’s ability to function properly. Periodically cleaning the unit’s vents will help assure maximum cooling efficiency.
Airflow
Proper airflow is critical to the performance of the WhisperKOOL unit. Any obstruction to the intake and exhaust ports on either side of the unit will compromise the unit’s ability to cool. Make sure the WhisperKOOL unit fan vents are clear. Check the front and rear intake vents for any possible obstruction. There should be a minimum clearance of three feet directly in front of the intake and exhaust vents.
