TROUBLE SHOOTING
PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION

2. Damper not working properly or
damaged

smaller duct
5. Fan body not securely attached
1. Be sure the CFM rating on the fan matches the
size of your room.
2. Check damper to ensure it is opening and
closing properly. If the damper has become
damaged, please call Customer Service.
3. Be sure you do not have any sharp bends in
duct closer than 18 in. to the fan discharge.

The fan is not clearing the
room

opened to allow airflow. The fan is not able to
draw air out of the room without enough
airflow to draw in from.
2. Be sure the CFM rating on the fan matches the
requirements for your room size.
