Review on 🔧 Nutone 8663RP Motor Assembly - 97017705, 1550 RPM; 1.2A, 115V by Nick Santos

There were a few fans that were getting old and freezing so I ordered a few. The first was very tight for the fan power connector and didn't go all the way as the metal pushed the connector up. I finally figured out the problem and found that the slot that allows this to happen was misaligned by about 5mm. Then I took out my dremel, trimmed the metal slot to widen it to allow the connector to fit all the way in without pushing it back, and heureka it went in, works great and is less noisy than the original. Aside from a slight expansion of the slot, this was a very easy swap. I would have given 5 stars if it wasn't for the small difference. I don't know what the cleanliness rating means
