Jennair gas range JGS8850ADQ touchpad circuit broken traces

17 November 2011 - 03:06 PM

Our jennair gas range JGS8850ADQ has finally died in the common way, and is showing an error F1-7.
Most of the mylar circuit traces have broken where the touchpad bends around to plug in to the clock assembly.
It started with the lower row of buttons failing, and then all but 2 and 3 and 'bake' - but the oven still worked. Now it just beeps continually and gives the error message.
So I assume the watchdog circuit in traces 20-1 and 19-2 has also broken. I tried to re-draw the traces with conductive glue, but it was too difficult and flaked off when I installed the touchpad.
Then I tried to just jumper traces 20 to 1 and 19 to 2, but that gave me error F1-8, button stuck down. I tried a few combinations of jumpers, but nothing worked.
The touchpad seems to go bad about every 3 years, and it's a rather expensive part. I would love to find a repair that doesn't require replacing it so often.

my questions:
Are there other watchdog circuits that I'm missing? Why doesn't jumpering the two traces fix the error? Do I need to jumper with a certain resistance - is it really that picky?
Some repair info states that if I unplug the touchpad and still get an error, that the clock also needs replacement. Is this true here?
Is it possible to buy just the mylar circuit ribbon and not the whole touchpad with backguard assembly?

And a question to send up into the ether: Why would anyone design an oven using a flexible circuit board where it will be directly exposed to heat, humidity, and vibration?
