DADoES:
I think the reliability of electronic control boards has a lot to do with the quality of the power supplied by someone's electric company. Here in the Atlanta area, we have an ageing infrastructure that contributes to frequent power failures in some areas, and surges. Those conditions are murder on electronics. In another area, with a better-maintained electric grid, they might be less problematic.
That still doesn't speak to the truly wretched availability of control boards once appliances are a few years old. We're all familiar with how rebuildable mechanical timers are- you send 'em to Reeco and you get 'em back like new. That's a lot harder to do with control boards. I have seen SO many later-model appliances in thrifts whose control boards are DOA.
All things considered, I'm sticking with mechanical controls. They're proven, rock-solid technology, and they're renewable. Can't ask for more than that.
