Thanks for the replies - this is a great site.
I'm going with a new motor, but the rear drum bearing felt strip is worn in some places and I think I need to replace this as well.
Is this a nightmare to do? From the pictures on the parts site, it comes with a tube of glue. How is it adhered to the drum?
My dryer, about 10 years old, has started to shut down in the middle of the dry cycle. I watched the excellent video on taking the dryer apart and took the thing apart. I noticed that the rear felt bearing strip had a couple of worn spots. I cleaned everything up, lubed the wheels, and reassembled it.
This helped for about a week, then it started again.
I notice that the dryer starts OK, and the drum turns pretty freely by hand. At about 1/2 hour into the dry cycle, the motor starts to make a loud humming sound. If you stop the dryer at this point, it will not restart for about 15 minutes. The drum seems to turn freely by hand, though.
Any suggestions on ways to troubleshoot would be appreciated.
Thanks
Paul
