Product review (5 stars): Fixed the problem and saved me lots of money.
As the other reviewers have noted, this switch is a great replacement for part #3406104. The wires are, indeed, a little shorter but this is actually a good thing. I screwed in the switch and it worked like a charm. The only challenge was opening the top of the dryer but if you google "open the top of a whirlpool dryer" you will find a cool video on YouTube by an Englishman that will tell you exactly how to do it. The switch arrived in only two days! Excellent customer service. Unheard of price. Perfect switch and outstanding reviews: It doesn't get much better than this! Thank you!
