Put a new belt on the dryer about a month ago and now the unit will occasionally not start...just hums. I took it apart and blew all lint and stuff from the motor. I taped the door switch leads together and started the unit without the belt and the motor works fine albeit a bit noisy. Seems like it has a harder time starting after drying a load of clothes. I lubricated the bearings on the motor, idler pulley, and cylinder bearing wheels. When it is running it sounds a little rough. How common is a motor bearing problem and I assume you can't change those and need to replace motor.
Thanks....first time poster.
