So I have the older, pretty sure the first style, SMC Emperor. In the last couple of weeks it started making this really bad scratching noise. What I don't get it has its good days and bad days. Some days will run silently and the other loud as all hell. When making the noise, the low speed really slows down to even stop working. I really would rather not get rid of it so is this an easy fix? ... or not.....
Thanks

When you spin the blades by hand, do they turn smoothly?

The scratching noise implies something mechanical, see if you can get it to do it turning the fan by hand. if it was just slowing down with no noise, I'd say bad capacitor.

The fan was having a good day. I ran it all day with no noise. I turned it by hand, no noise. Maybe an hour later and I turned the fan my hand and made the scratching noise. Then I turned on the fan where it made the scratching noise.

Check all of your screws. Maybe a loose motor housing is rubbing against the blade irons, or the motor. Open it all up and see if any particular part is loose.

It could also be a wire nut. The fact that it did it when you turned by hand means it is a mechanical problem.

Spinner + motor housing + grinding noise = probably a loose nut, screw, wire nut, etc. between the motor housing and the motor itself. When I was younger, one of our Tyebs started making the scratching/grinding noise, and one day it was on and ground to a sudden halt. I thought the fan was rendered useless until I got the idea to take off the motor housing. Bingo, loose screw was rolling around in there, and to this day I have no idea where it came from. Take off the motor housing (you'll need a screwdriver and, if it's your first time, a lot of patience) and see if something doesn't fall out.
I don't think a bad capacitor would cause a grinding noise, although SMC's have historically had the worst capacitors in the industry by far IMHO. Regardless, that might be a good second place to check if the first idea doesn't work.

No, not a capacitor, it wouldnt case a grinding noise, especially while the fan was off.
SMC's had bushing bearings, not ball bearings, so they are notorious for bearing problems.
