I just had the buzzing sound and it ended up being lint packed in the motor housing. It very well could of started on fire. If you have that buzzing sound go on Google and look up your model to see how to take the panel off to get to your motor. Even if you can get it moving again by some of these suggestions it doesn't mean you still shouldn't get in there and check why it buzzed in the first place. I took out a couple handfuls from mine. My dryer is an older GE model and other than the drum comin off with the front panel it was fairy easy. If I would of know that I could of had someone reach in and hold the drum in place while I pulled the front panel off.
