My Ge double oven convection range just shuts off when warming, this happens with either oven. The display just goes back to the clock and does not display any error codes. This was a intermittent problem but has become very frequent. Eventually it will get heated up after turning it on numerous times and work fine. Also for quite some time we have not been able to reset the clock and sometimes have to play with the top oven control touch pad, we use this oven most of the time, to get it to start heating. I'm guessing its either the control board or touch pad but both are expensive so hoping for the right answer.
