YouTube said the number one problem with Whirlpool dryers is the belt is broken. I opened up my dryer and saw that the belt was indeed broken, ordered a part from appliancepartspros.com and used a YouTube video to replace the belt. I had to go slow to make sure I was doing it right, but it was very easy to do and now my dryer works again. Took about 2 hours, my FIRST dryer repair. Yay!
