Code F0 GE Oven

I have an F0 code on this GE oven. According to the manual, F0 means "Shorted OFF key". Upon powering up the oven, the oven works perfectly for 5 minutes. All buttons work and the oven heats as expected. After the 5 minutes there is a beep and the keypad no longer works. After 5 more minutes the K0 code comes up. Turning off the power will yield the keypad working for 5 minutes again and the K0 coming up after 5 more minutes. During the first 5 minutes the keypad works fine and passes the keypad button test in the manual. None of the buttons are shorted. After the first 5 minutes no buttons work. Any suggestions of what the culprit it? Thanks!!!

Hi.

Check the flex ribbon connector with the magnifying glass for small cracks. Clean the both plugs with the electrical contact cleaner(power to the oven is off). Let it completely dry before powering up.
If all this doesn’t work and the ribbon is OK - replace the control board.
If you get it from APP you can return it even if it’s been installed.

Good luck. Post the results.
