After using the self cleaning option the oven went dead....nothing on display. After testing I found that the in line fuse located behind the control board was blown. I replaced this fuse and the display lit up. However some of the buttons in the panel did not work. So I repaced the circut board thinking this was the problem. However, this did not fix the problem. The only controls that work are: temp"down"; delay start time; hour "up"; upper off, and lower off. I think that the control panel is bad but I spent alot on the circut board and I don't want to guess again as it is very expensive.
