I too am in the midst of diagnising the dreaded Fi fault on a Jenn-Air wall oven and then repairing the various part(s) that might be at fault.

I doubt that I will ever understand "how" or "why" this got started, but I do have a good friend whose house was struck by lightning and 100% of his "digital" appliances (washer, dryer, range, ovem, microwave, stereo, etc) all 100% were zapped.

Although I'm sure that the manufacturers build some sort of surge suppression into their products, I do NOT see any real good protection built into my oven's ERC timer (built by Robertshaw controls).  Plus, the entire clock circuit is in an environment (above the oven) that gets pretty warm, so i can see why it failed.

Now, if someone would only tell me whether it's the membrane or the clock; too many decisions to spend so many dollars!
