so about 2 months ago our top oven stopped heating. we were told by reputable repair man that it was the control board. due to other expenses we elected to wait since we had the lower oven to use.

you guessed it, now the lower has done the same thing.

I was about to order the control boards and DIY it when I discovered that there is a "main" board as well.
So, since the two ovens failed with about 2 months between them, is it fair to assume that the issue is the individual control boards and NOT the main board? timer and clock are operation fine.

thanks in advance.
