TROUBLESHOOTING
PROBLEM
POSSIBLE CAUSE
SOLUTION
The fan seems louder than it
should.
The CFM is too great for the space.
Be sure the CFM rating on the fan matches the
square footage of your room.
The damper is damaged or not working properly.
Check the damper to ensure it is opening and closing
properly. If the damper has become damaged, please
call Customer Service.
The bend in the duct is too close to the fan discharge
.
Be sure you do not have any sharp bends in the duct
within 18 in. of the fan discharge
.
The fan discharge is reduced to fit a smaller duct.
Use the recommended size ducting to reduce fan
noise.
The fan body is not attached securely.
Be sure the fan is securely attached to the ceiling
joists.
The fan is not clearing
humidity from the room.
There is insufficient airflow intake in the room.
Be sure a door or window is slightly ajar or open to
allow airflow. The fan is not able to draw air out of the
room without enough airflow.
There is insufficient CFM.
NOTE:
Using a tissue is not the correct method for
determining if the fan is operating properly. If the fan
clears steam from the room within approximately 15
minutes of completing your shower, then the fan is
operating properly.
Be sure the CFM rating of the fan matches the
square footage of your room
.
