My mazzer major is acting weird. It jumps/moves around on the counter. When I start it, It first seems to stall but then it starts and it starts to jump/move around on the counter. I've clean the burrs and the burr chambers but it didn't help. If i rotate the the lower burrs by hand
, It rotate easy without any noise. So I don't believe it could be a mechanical issue like bad bearings.
Could it be the motor windings that's gone bad?
Does any one know what resistance I should be on the windings?

Bouncing around implies that something might be unbalanced. Did anything get jammed? If you adjust to the point that the burrs touch when it is running does it have a high or low pitch sound?
