Product review (4 stars): Perfect Fit for Nutone Range Hood But Pricey
The bearings on my range hood fan motor failed, causing it to slow to a crawl and make a horrible squeal. I had to decide between purchasing a new hood and buying this replacement motor. I decided to replace the motor since it only required removing the cotter pin for the fan and the four nuts holding the motor in place versus removing and rewiring the whole housing.

The replacement motor arrived as promised and was an exact match for the original. The downside was the price which was only about $30 away from replacing the entire fan.
