The art of doing stuff has great article on how to do things yourself. I really like this one on how to fix your dryer. Last time I called a repair man to come fix mine he pretty much told me it would be cost comparative to just buy a new one.
Nope I am not kidding that is what he told me. So I went searching for a way to fix it and I found this article and sure enough it worked.
So if you ever need to figure out why your isn’t working if you have this bookmarked you may be able to repair it yourself as well.
