Product review (3 stars): Hood Fan Motor
The item arrived quickly.  It appeared to be working. The vapors were not going upward.  The fan just blew air circular and cause my smoke alarm to go off.  The mounting brackets/motor set lower and different from the original therefore the filter would not cover it.  I was going to take it down to change blade directions to make it work, but it stopped working.

The company is good about refunding purchase.  I do appreciate the fast refund.
