GE Profile TrueTemp Oven F7 error

I keep getting F7 error code on the display even when is not in use. I pull the control panel out and unplug and plug back the ribbon cable. This seems to reset it for a while but then the F7 error code comes back. Do you know if I need to replace the Electronic Oven Control Module or the Panel Control Assembly? Anyone experienced this problem? Any success in correcting this problem?
