Took drum out to replace parts guided by repair videos. Also replaced drum belt and belt tension (idler) puller "while I was at it." Took the opportunity to inspect other parts and vacuum-out lint that accumulated inside dryer over some years. Very pleased with repair experience, and Appliance Parts Pros' repair videos and speed of parts' delivery. (I am a repeat customer.) 'Saved me money and the appliance is operating "like new."
