Product review (5 stars): Fixed my problem
I bought this motor after trouble-shooting a couple different areas of my dryer.  The dryer wouldn't turn on but the heating element would engage full blast whenever the timer was set to anything other than "off".  I thought the heating element might have been grounded out, but it was fine.  So was the thermal fuse.  I bought a new timer motor based on the recommendation of an electrician in the family, but that also didn't solve the problem.  Turns out the problem was a switch within the the drive motor.  I swapped out the motor with this replacement (slightly frustrating process, but not impossible) and everything was gravy.  I'm not an expert, but I think the problem was a little spring connecting two parts of the motor.  One of the two springs on the old motor had broken, and I'm thinking that they controlled the switch.  Don't take my word on it though, I'm an accountant.
