Question about Broan-NuTone Allure III QS330SS Kitchen Hood
This has nothing to do with the wind. Our house was recently built. The duct for the Broan fan system beats fairly constantly whether it's windy or not. It's continuous and regular. Yes, before reading this page, I found the source of the noise. Yes, it's the exterior flap. I've noticed that it seems to be caused by a difference in the interior air pressure. In the winter, windows and doors are closed and the thumping seems to be more constant. If I open the back door in the kitchen, however, the noise stops. Sometimes, on the other hand, it stops by itself. I actually called Broan customer service and I'm a bit unclear, but it sounded as if others may have complained about this. For what it's worth, the representative recommended weather stripping around the vent.

Its probaly the duct. There is a little hinged door which is in the ducking right where the fan connects to your duct's, somtimes they play in the wind. I have heard this problem before. Is the clicking perfectly sycronized?
