I just started to have this very same problem with my Kenmore 4.3. Krushing and grinding sounds and only the first time any burning electrical smell. Vacuum works and sucks up. I think something needs to be oiled or lubricated in the spinning hot wheel. There is one spot or hole that appears to be the place. The question is oil or lubrication?I love this vac for my sewing art studio and I can't afford to lose it now. Any retired vac repairers out there to help? MCH
