Thanks for the information. It works well and is quite powerful, but the bearings are due for replacement.
My other problem is when I removed the power switch to clean it, I accidentally pulled (or pressed?) it; it fell (exploded) apart, and various parts went flying around.
I crawled on the floor and even pulled the refrigerator out of its spot; I think I managed to find everything except for a bracket that seems to be missing—and I just can't find it. It’s driving me crazy. I think it was a flat kind of thingy. And yet, I don't even know what I'm supposed to look for.
If there’s no other choice, I don’t mind buying a new replacement switch—but again, I have no idea where or what to look for, or what they’re actually called.
Again - your help is much appreciated.
Enclosed the parts that I managed to find.
