Bruce I just had a brainstorm, what is the best oven board out there?
JW,
You ask a great question! I don't think it's been designed yet ... but I'm thinking about it

.
or ... it's the board that has never entered our shop ... so we haven't seen it!
It's an interesting design problem, not only electronically, but also from a thermal and mechanical point of view. How the board is shielded from the high temperature of the oven cavity and, believe me, grease splatter can have a big impact on its reliability. And, as we've seen here, sometimes, in an effort to add cool hidden features, the marketing guys outsmart themselves with unintended consequences. The details are subtle and of course that's where the Devil and Murphy conspire...
You've got me thinking to start a separate thread on this subject. With all the knowledge and experience on this forum I think we could develop a design criteria for the ultimate high reliability, long lifetime, intuitive user interface, etc, oven controller. I mean, really, why should an oven fail to the point of replacement in our lifetime ... it's a steel box with some heaters ...
Keep on with those thought provoking questions!
