My dryer was heating up, then shutting off. I read some posts and it sounded pretty much like the burner coils. I replaced the set and thought I was home free. I turned it on after completing the work and the flame went on for about 20 seconds then shut off. I could hear some periodic clicking, then the flame would come on again, after a short while, for another 20 seconds or so and shut off again??? Based on what I've described, does that sound like something anyone may be confident in diagnosing? Any help would be much appreciated.
