George G Waukesha , WI March 07, 2017 Appliance: Model LG TROMM 6DTD0340 Bad rollers Although only two were bad, I replaced all four rollers and the belt while I had the entire machine tore apart. The belt probably did not need to be replaced but to help minimize the need to replace it at a later date I replaced it. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
