Last Saturday, the dryer stopped working. The heater still worked, but the drum itself didn't tumble even though you could hear the motor/blower going.
So on Friday I decided I was going to fix it. At first I tried taking off the back, but quickly realized you couldn't access the drum from there. It did give me a chance to clean it out though.
So I looked it up and found a guide for Kenmore 500 series dryers here

. To get access to the drum you need to remove the lint trap, the two screws in the trap, and then slide and pop the top off. After that, there are two bolts holding the front panel on.
When I took it off, I found the drive belt on the drum was completely slack. So I took the drum out, and found the belt tensioner was on the ground and the belt was connected to nothing. So I cleaned out the machine, put the drum and tensioner in , and reconnected the belt, making sure it was on the wear line. It took about an hour, but the dryer definitely works.
Here is a diagram from the appliancerepair.net website:
I definitely feel like I could be an appliance repairman if I needed to.
Heheh.. I had to look up at the address bar to see if I was again in Paul's journal. :) Clearly, you are peas from the same diy pod.
