Dryer was getting hotter than blue-blazes, melted synthetics, damaged belt

Removed back of dryer, there were 3 screws on each side. There were two thermostats on the output vent and one thermostat on the heating element housing. Adjusted the temp settings on the thermostats per the instructions received with each thermostat (cross-refernece of original number required). Each thermostat had two screws and two wires. Terminals were coded "1" and "3," must get correct wires back in same place. The heating element thermostat required to splice new connector on one wire (per instructions enclosed with thermostat).. Easy as pie. BELT: Remove screws from lint screen housing, then pry up front of top of dryer and swing back (make sure you are next to the wall so it doesn't fall.) Remove the bottom front panel, remove the door tension springs, remove the two screws on the front of the front panel and remove the two top screws on the inside of the door panel (leave the door attached, but use tape to hold it shut so it doesn't hit you on the head) Careful of the door switch wire, carefully lean door up so it doesn't fall. The Drum will fall when front panel is removed, so have someone to help you hold it up. You do not have to remove the drum. With your frend holding the drum, go under and pull the tension spring roller back to slack up the belt and remove the belt from the tensioner and motor pulley. Remove belt from drum. Wrap new belt around drum (ribs down facing drum) and re-route belt around pulleys according to diagram in instructions (same way you pulled it off). I did it by myself, but I got konked in the head by the door, so be careful. Easy, but awkward. Watch for sharp sheetmetal edges.
