if the clutch is locked ... or tight... then the drum would be more likely to not STOP turning...
If the clutch were loose then the drum would not engage with the motor...what brand , make model serial number?

wheel bearings or bad belt.. woese case motor

Was the belt shredded ( normal wear & tear ) or burnt through which could be a drum bearing or support problem .What does the drum feel like when you turn it by hand is it grinding & lump ? The fact that the motor runs with no load could by the start device faulty these are reasonably cheap to replace this is the small cylinder attached to the side of the motor with two wire connections . if your motor has not got one of these then its the start windings in the motor

Check the motor brushes and belt.

Could be:
1. Broken spring(unlikely)
2. Bad shock absorbers (maybe)
3. Broken spyder-the Inner drum part that holds the drum to the hub(kinda likely). If inner drum can be moved without outer tub also moving in tandem, then broken spyder is likely.
Good luck

look for a broken pin between the two parts

How could the belt be in working order if the drum doesn't spin? Check to see if the belt has come off the motor. If the motor runs but your dryer doesn't spin, the belt is off. If the motor runs with the belt on but it still won't spin then you'll have a lot of black smoke because your drum is jammed. In other words, there are a number of things that could be wrong, but not very many.

Hi How old is it , ? and dose it soun like the motor is running but not turnning the drum ? this would be a bad belt , you will need to do some more investagating for me to help you

not a good model number,most likely you have a broken belt as long as it starts,heats but the drum doesn't spin,if you get a buzzing sound and it doesn't start you could have something stuck in the blower wheel,the motor is jammed or the motor is bad,you can open the door,push the door switch in,spin the drum with your other hand and have someone push the start button,if it starts you have a bad motor.
