With power disconnected, I can't turn the shaft. Is the shaft supposed to be loose enough to be turned with my fingers? Could humming also come from a defective electronic board? Thanks.

Perhaps something was stuck in there before or there was too much lint (I vacuumed the motor). Thus, I reinstalled the motor, testing it now and then with no problem. After dryer was put back together, motor returned to a humming state and eventually quit. After a few minutes, I could restart it, but then it would quit again. Is this the sign of a tired motor in need of replacement or could there be too much stress somewhere. Thanks!
