Disassembled sheet metal, plastic shroud and lint filter receptical to access blower fan - replaced it. Easy fix with a #2 Philips head screwdriver and good light. Small pop in clips inside lint filter that took a while to find. They are installed from the inside of the drum and I didn't see them at first. The people who sold the combo to me had been quoted $400 to "fix" their dryer that wasn't working. Best purchase in a while for me - almost new machine for $194 including the part I bought from Appliance Parts Pro!
