Our dryer was making such a load noise that we deemed it unusable. We weren't sure if something would burn up if it continued like it was. So I checked a few articles on the internet and everything pointed to most likely the drum belt. Ours looked a little worn but not really that bad so I got the part. I then followed the repair video that AppliancePros had posted for my model (which was great) and installed the belt. Still squeaking. So I went on to #2 on the list of possible problems, the drum wheels. A couple of ours seemed a little less free than they should be so I got the parts and installed those guys. Still squeaking. So I went on to #3 on the list the dryer pulley. By the way, it is really hard to figure out where the actual noise is coming from since when you actually run the dryer everything is closed up so you have to kind of guess and inspect each of the possible problem areas. I sprayed some lithium lubricant on the pulley wheel and no more squeak! (for one load at least and then it came right back). So I got the part, replaced and everything is good now. In some weird way I think I should get a journey repair certificate for all my effort ;). My only regret is that I should have gotten all the parts and replaced all at once. Kind of a dryer tune up. I would recommend getting the belt, wheels, and pulley in one shot. It is cheaper than all of the shipping costs that you will incur if you don't guess right. One last thing. AppliancePros gets the stuff to you in 2 days if the part is in stock. That really helped save some skin with the wife while the dryer was down.
