What To Do If Your Big Ass Fan Makes This Sound 

I thought this was going to be a promotional video, like "if your fan is making loud overpowering 'whoosh' noise, that's normal."

Good idea

I purchased one a long long time ago. Tried to send emails to customer service and they were not any help on fixing my fan issue. So now I have a fan in which the switch box is blinking and won’t work. I even sent customer service a video to show the issue.
