Went to use oven tonight. After a short period of time while stove was warming up, heard a beep coming from the stove and black smoke started to come out from behind the touch panel. My son tryed to turn on the downdraft fan and this caused more smoke and sparks to come out from behind the touchpanel. Once the "cancel" button was pushed, the smoke and beeping went away. The burners on the top of the stove work fine. I didn't see any codes flashed on the touchpanel. Any ideas on troubleshooting?

Function key shorted or stuck button
Replace touch pad or clock assembly (also called the ERC) or attempt to un-stick button

Shorted key sensed for 32 seconds
1. Membrane shorted, or,
2. Display board defectiveIf touch pad is a separate unit then unplug it and see if code comes back. Unplug range before doing so. Once touch pad is disconnected, plug range back in and see if code shows. Wait a few minutes. If no code then replace touch pad. If code does come on while touch pad is disconnected then replace main control. If touch pad and main control are all one part then replace the whole control. Doubt if you would have any luck trying to unstick the bad button as stated above.

Unless they start working again after it has a chance to dry out the touch panel will have to be replaced. This happens when excess moisture gets between the very thin layers of the membrane.
