I was getting ready for a bike ride this afternoon and hunting through the dryer for some gloves when I spun the drum by hand and it made a huge bang. Hmmm, that's weird, says I. I find the glove and attempt to restart the dryer and no joy, no spin, no heat, no nothing. So I make the executive decision that this is not going to ruin my ride and inform the family that laundry is off limits for a while. Got in a good ride with two local buds and then got to work.
Initial prognosis, the belt is still around the drum so deeper we go...
Problem found, the belt had slipped off the idler pulley and then the spring that loads the idler had fallen off so the whole drum had to come out to get at things to perform the relatively straight forward repair. About a half hour later everything was back together and working. Worst part is that the belt is worn so I'll get to do at least half of this again sometime sooner than I'd like but at least it's working again.
