My husband and I did the repair after some diagnostics with an ohm meter and found the timer had failed which was causing the dryer to run until the thermal fuse would fail.Doing further diagnostics the switch and the resistor had also failed.This dryer has served us very well for the last 20+ years and the thought of replacement was our first thought but we checked the parts prices from Appliance Parts Pros.com and figured we would give the repair a try.The dryer housing and tub still looks in great shape because it's been taken care of and replacing these parts has this dryer running like new again so our dryer repair and tune up of wheel replacement was the right move for us.
