Long time lurker here. This project/discussion caught my attention because I am in the planning stages of a similar project. With proper planning, forethought, and engineering, of course cash, this project is absolutely doable. The OP appears to be taking his time to carefully think this project...
All good replies above. Just had the same thing happen with my dryer.
- check the vent duct
- check the thermisistor with a voltmeter for resistance. This is what when bad with mine.
I replaced the glow burner and the solenoids as well for good measure.
Wife says is works well now.
Cheers.
