I need your help.
I have a 2002 Kenmore 80 Series (aka Whirlpool 29") gas dryer model number 11072822101. I've owned it for 5 years. Before that it was in storage for 6 years. Before that it used "regularly" before that (I didn't think to ask the prior owner how often that was). When I got it, the lint wasn't too bad, but definitely not cleaned regularly. I kept it and the exhaust duct whistle-clean during my tenure and use a surge protector.
A few weeks back, it ran, turning the drum, but did not heat. I did not know to check the peephole for a flame. However, I checked all fuses on the back and connections; everything was fine (ie continuity present and no corrosion). I then tried to run the dryer again, this time looking through the peep hole. I saw the igniter glow and a blue flame appear. I then ran 5 loads without problem.
I also checked the drum belt, which looks like new.
Any idea as to what was wrong?
In general, what's the longevity of this model?
Is this dryer a keeper?
What sort of problems commonly occur with this model?
What sort of spare parts should I keep handy?
What are good places to find replacement parts?
