This has me stumped. I have a NuTone 100CFM bathroom fan+light fixture (the big circular light). The fan was spinning slowly and was making bad noises. So I took it apart, cleaned the wheel. It ran great when I tested it by plugging it in to the wall. Very smooth, and lots of air movement! But when I re-install it back, I get some noise and I don't feel the same breeze. I messed around a little bit with the motor mounting nuts and tried to feel if I can locate the place where the fan wheel aka squirrel cage was rubbing somewhere. Nothing jumps out at me but obviously something is wrong because it is not as quiet as it was when plugged in to the wall. I must have taken it down at least three times in an hour, so now I am pretty good at it
Any tricks or suggestions?
