Product review (4 stars): This unit was a good replacement, there are only two complaints I have ...
Our range hood fan had been damaged by careless roofers years ago - they took off the roof jack and didn't put anything to protect from debris falling down the exhaust duct. That resulted in the original fan's squirrel cage getting bent and contacting the housing. This unit was a good replacement, there are only two complaints I have - the vendor I bought the part from salvages good parts out of damaged units (making the price very attractive) and when they removed this one, it looks like they broke one of the tabs that retains the motors power connector into the hood. There was still a good one, so no big deal and given the hidden location, I would have been fine zip tying it in place to hold it together. The other complaint is that the mounting flange was different from the original. Wasn't a big deal, though we already had the motor in place hanging by the shoulder screws and didn't want to take it back down, so we just had to drill a couple of pilot holes to be able to secure it with the sheet metal screws. If we had noticed this difference ahead of time, we may have been able to swap the mating flange from the original assembly.

Overall, this product works great, and it's nice to have a functioning hood fan again. Just wanted to put these notes down so someone else may be able to benefit in the future. Also worth noting, the cheapest I could find this replacement was $100 more than buying this "salvaged" new part. Well worth the couple of issues we ran into.
