Very noisy.

My first attemp was to replace the drum roller and idler roller, drive belt, and the felt seal for the back, since I had experience replacing these on an older machine many years ago. The dryer was very easy to work on....After installing the new parts, I reassembled and discovered it still made the same loud noise. I then, disassembled for the second time to discover the blower wheel was worn out; so i ordered another blower wheel and a drum support roller (i only ordered one the first time.). After reassembling it made an annoying high pitch sound. I attributed that to the new parts...probably the new belt and new felt seal. Gave it some time to run-in and it seems to have quieted down. Overall, i found the dryer very easy to work on. I actually found the felt seal the most onerous to install....needed to have about three hands to get the drum back in place! I just wish that the stamped metal dryer housing didn't have such sharp edges. I had to be very careful to avoid sharp burrs but still got nicked a couple of times.
