How do I fix my Kenmore Whispertone 116.3481920? Brush not rotating?

I am not a repairman, but I earn a living doing residential renovation. And from what I Know, having to deal twice with the same problem on my client's vacuum, you can force the motor to turn a few times, either using the brushroll to induce movement or, having removed the brushroll and strap, using a pair of pliers on the shaft of the motor (there's no danger of breaking it), it might work. Sometimes, rust or dirt can jam small electric motor. You can try shooting WD-40 inside and around the engine, and force again the engine, and try it normally. But I would wait 5 minutes for some of the chemicals to evaporate to avoid risks of fire. Good Luck!
