Dryer not spining but heating

:confused: Hi There,

Please help me if you can! I have a Whirlpool Dryer, it is about 3 years old. 2 days ago stopped working, it not spinning, just making a buzzing noise and heating up very quickly, the light is working. The drum can be moved manually, the belt looks good. I checked the thermal fuse and was burned so I replaced, but still is not working and making the same noise.What else could be? :confused:

Thanks a lot for your help.
