Replaced heating coil. Machine was also loud; replaced support rollers, drum belt and idler pully. Replacement of the heating coil on my model requires removal of the drum to access the heating element housing. Remove top attachment bracket and assembly drops down. Unhood wire connections, slide old heating element out and replace with new heating element. Remove old rollers, clean and lubricate shafts, and replace with new rollers. Replace idler pulley and reassemble. It was an easy fix, although involved.
