After taking off the front cover, as explained by someone else, I found a bracket holding the drum belt was very loose. The belt was on the verge of breaking. The drum blower was scraping on the chassis. The parts were so reasonably prices I purchased those three plus the drum rollers and slides. Result is a completely rebuilt dryer for less than $100.00. Complete rebuild in 1 1/2 hours. I've already recommended partspro to several friends.
