I think I know the answer - but: With the dryer "off", when you turn the timer to any position other than "off", the drive motor hums. You can then spin (by hand) the drum (while opening the door and holding the door safety switch in) and the dryer will run/heat properly. I believe the starting switch on the drive motor is stuck in the "run" position and is not releasing/going back to the "start" position when the dryer shuts off. Could someone confirm my analysis? (I've seen this before with Kenmore dryers.)
ANSWER Hello Nrm1943. You are correct. You will need to replace the motor assembly 5303283470 to fix the problem. Hope this helps.
