How to Troubleshoot & Replace Whirlpool AP6008781 / WP37001164 Switch, Temp - 3 Posi

I replaced the two thermostats and that worked briefly then quit. Dryers are pretty simple and the element tested good, so the only thing left was the temperature switch which I ordered. ApplicancePartsPros said they would return my money for any reason so I thought I would give it a try as this offer gave me nothing to lose except shipping and the possibility of saving $500 +, the cost of a new dryer. It worked.
