Hi, recently this morning my drier began to make a loud tumbling noise and slowly receded into a high pitched squeaking noise and the drum completely stopped revolving. After removing the front of the door and looking around under the drum, I manually spun it and saw that one of the fan belts was hanging on by a thread, and that a Roller had no fan belt attached. I was unable to see if there was a fan belt under the drum that was hanging off of it or if it was completely broken, but I believe it's the fan belts. If so, how would I go about replacing these myself? I also was reminded that I forgot to pull the plug out when I was moving the front door back into position, and a wire that is connecting to the loading door (it looks like it connects to the safety button that allows you to start the drier) sparked, smoked for an instant and now looks burnt. Could I have burned that out just by that one incident?

Thanks if you can help.
