I swapped out the inner and outer thermal limiter switches as well as the thermostat while I had the dryer opened up. The videos on this site made it easy for a novice to do alone. It took a few hours and some patience but the machine works perfectly now and saved me from buying a 1k+ new dryer. I believe only one of the limiter switches had failed, but the parts are reasonably priced and the effort is spent in the disassembly and reassembly of the machine. It was best to order the most common parts that fail for that model and switch them out all at once. I was also able to clean out the inside of the machine and then run a better hard-line exhaust for the dryer.
