I removed the part and I don't see anything that opens or closes. However, it does have a power cord that is connects up test it out before paying over 220 for something I may not need.
When you look at the bottom of the damper assembly there is an opening. You would want to check the door on the damper to make sure that the door is not broken. If broken it will need to be replaced. To test the unit you would test from the control board in the back to make sure that power is being supplied to it. If there is power then the part would need to be replaced. If no power then the control board is the issue.
