I googled my model number and came up with their web site. I looked at some of their trouble shooting videos and confirmed the belt was the issue. Watched their installation video for the belt then ordered the belt and idler on a Friday. To my surprise the belt and idler was delivered by Fed-ex the next day on Saturday. My 11 year old dryer was back in service on Sunday. My wife was ready to right that dryer off and buy a new one on Monday. Hopefully we will get some more years out of it.
