After looking at the wiring diagram,I discovered that someone had removed the wires from the thermal cut off on the heater canister and crimped them together ( Red/white to black wire) and had been running the dryer like this.Also I discovered that where the power cord goes to the termal board on the back of the dryer the middle wire,ground wire, has burned off and the power termal is burned.And the thermal fuse going to the motor is open.What do you guys think?Should I try to fix this thing,or could something else be wrong here?
