My old GE Profile dryer has stopped working. Every once in a while, when it was working, I would hear a click and once that happened it would stop heating. If I turned it off and waited a little and restarted it would run fine. I have had it not run at all when I turned the start knob but waiting a little it always started. Now its dead completely, The light is on inside the drum so there is power. I was wondering is there a relay or something that causes that click I hear when it stops heating prehaps thats the issue or maybe the start knob? Any ideas would be helpful.
