I purchased a second-hand Kitchenaid KERA807 Architect Series Electric Range.

When I got it home, I found that on the front membrane switch for the oven, several of the buttons did not work. I have included a link HERE to a picture of the membrane switch. On this switch the following buttons would not respond:

CONVECT: Bake, Broil
EASY CONVECT: Meats, Baked Goods, Other Foods
3, 4, 5
Options

Though the Timer buttons worked, there was no audible sound that beeped when the timer ran out. All of the other buttons worked.

So, I ordered a new membrane switch. When I installed the new switch, I tested it out and every button worked and functioned exactly as it was supposed to. (Pretty lame timer alarm, but it worked.) My wife was very happy because now she could use the oven.

The next day she cooked and baked for a better part of the day but when I got home she complained that the Start button was not working well. It sometimes worked, but she had to press it and play around with it multiple times. So I pressed the Start button it did not work at all. I began to press some of the other buttons and to my disappointment, the following buttons now do not work:

CONVECT: Bake, Broil
TIMER: Set/Start, Off
START

All other buttons seem to work (at least for now).

I then noticed that the clock was not working. So, I tried to set the clock and it would not respond. I then turned the breaker off for about 20 seconds and turned it back on. Again, the clock would not respond. I also noticed that, within a few minutes, the oven was heating up. I looked inside the over and the top element did not seem to be hot but inside the ceiling of the oven and the stove-top heating elements something was glowing red inside. I can't imagine there's an element in there, but something was pretty red inside there and there seemed to be heat emanating. If the broil element is above the oven ceiling, then this was likely the broil element.

Anyway, I went back downstairs and turned the breaker off for about 10 minutes. I turned it back on and the over had stopped acting strangely and I could set the clock. However, the buttons on the membrane switch are still not responding.

If it were not for the fact that, when I replaced the membrane switch, I would think it was the Electronic Control Board. I mean, maybe that's what it is, but then why would it work perfectly when I first replaced the Membrane Switch?

HERE is a link to the parts pages to have a look at all of the parts.

Any ideas of what my problem could be? I would appreciate any help since we're stuck with an oven that is useless currently. Thanks!

Going to give the guys a tech sheet for what I guess is your model?

OK. So, this is incredibly embarrassing, but we figured out what the problem was. Above, I wrote that, when I came home, my wife said she had been working the START button. Well, if you hold the START button down for 5 seconds, it locks the oven. (I actually knew this!!!) Anyway, my wife unwittingly held the start button down for 5 seconds tonight and, voila.

Anyway, thanks for the views and the brainpower from you guys. A little egg on my face.

No worries, it happens to everyone, including me.:)

Glad that's all it was!

Thanks for the update!

Well, I hate to be the guy who keeps coming back, but I'm back.

I was elated to find that out control panel for the oven was working. Went away for a week on vacation and came back to find it not working again. Same problem as before. So, I guess, it turns out that the problem was not the safety lock setting on the membrane switch.

So here's what I'm wondering. Given the fact that the membrane switch worked, didn't work, then worked again, and now doesn't work again and that it, really, is just a bunch of contacts sandwiched in an airtight membrane, do you think that it's the membrane switch or the Electronic Control Board (AKA the brains). It'd be great to get some feedback on this.

Thanks!

Ok,

Well, since your already replaced the membrane switch, then it can only be the oven control board that's causing this now.

Here's the oven control board for your model:
Oven Control Board WP9762812
