Drive belt and lint inspection
I pulled the dryer out and opened the cabinet to inspect the drive system. The drum belt needed replacement, and lint had collected around the blower housing and inside the cabinet.
The exterior vent was also restricted. The wall opening and old vent hood show how much lint had accumulated at the outlet.
Belt replacement and vent cleaning
I installed drive belt 4400EL2001F around the drum and idler assembly, then cleaned the blower housing and cabinet. The wall vent was cleared and the vent hood was replaced.
With the front panel and drum assembly back in place, the dryer could turn normally again. The invoice total was $319, with a 6-month warranty on parts and labor.
