Jeffrey I have an LG DLE5977S Dryer. When I turn it on it just hums. I took it all apart and cleaned it and reassembled it. Does the same thing. When I had it apart I checked motor and it spun with out the belt on but started slowly. I lifted belt tensioner to test motor. All rollers are turning freely. Thanks for your help. Jeff
