Ge wall oven display says F7

Here is the photo showing my solution. I have now shared this solution with over 800 individuals. Most report success. This problem is caused by a design defect in all GE and Kenmore ovens.
The technical name for the problem is called Dendrite growth. Many electronic devices have failed because of this well known problem. GE could have prevented this problem for only a few pennies.

Follow up to the paper solution.  After inserting the cards where shown, I also had some errors F7, F0 occasionally.   After some testing, the error quit immediately after pulling the panel out slightly.  I looked and my ribbon cable appears to touch the electric light terminal for the top oven light.  I put a piece of shrink tubing over the lamp terminal to insulate it from the ribbon cable.  So far the problem has stopped.   For those with continuing problems you can look for another contact point such as the bare terminal on the light fixture (top oven in a GE wall mounted unit).

That's it!  Not only was the paper required per original post but on mine the above insulation of the light bulb wire behind the ribbon cable was also needed.  Since then I have had no more F7s.    If anyone having F7 then also check where the ribbon might be touching a wire when the panel assembly is pushed back into place.  This ribbon was rubbing up on 110v lamp post wire.  Wherever that cable might touch something just protect it and F7 be no more!
