Oven Repair (including Ranges and Cooktops)

I have a Maytag single oven that fits in the wall. The control panel started malfunctioning. The oven went into sabbath mode on it’s own and when if finally came out only the cancel button and numbers 3, 6 and 9 respond. They don’t do anything other than beep though. I installed a new controller board, but that did not fix the issue. Any help is appreciated. Thanks
