So this is a common way for display boards on these GE ovens to fail I'm sorry to say. The problem is the the logic inside the board is corrupt so it eventually just shuts the program down and the oven reverts back to just showing the time of day. You can keep trying over and over and sometimes it'll work but you'd need to replace the display board to resolve the issue. Possibly the jostling of the oven when being moved caused the board to vibrate enough to cause the problem but either way, the display board would need to be replaced to resolve the issue.
