I have a 27" Bosch Double Wall Oven that does not come up to set temperature. I replaced the temperature sensor, it is good. I tried to replace the control module, but the display will not come on with the new module. The only thing that works is the oven light. If I replace the old control module, all functions attempt to work. Is there an initialization sequence needed to get the control module to work? I've tried two new control modules with the same result.

I have the same problem, did you sort out a solution?

I have read that if replacing the control board, also replace the display board.
