Ordered a kit with new belt, rollers and idler pulley. Used instructions in kit, YouTube videos and instructions I found under the console of the dryer. Found that the idler pulley had frozen and that the belt was nearly worn through. Repair it self was not difficult. The problem I had was in hooking the new belt around the idler pulley. It was solved by removing the one screw holding the air discharge tube and sliding the tube rearwards. This allowed me to get my arm in behind the idler pulley and hooking it around the new belt. Remember to remove the clip holding the discharge tube at the back of the dryer so the tube can slide back giving you room to reach the idler pulley.
