I searched the net with my GE Trivection oven model # JS998SK3SS and symptoms and found this thread. http://www.applianceblog.com/mainforums/threads/37269-Profile-Oven-display-is-blank-and-oven-light-does-not-come-on
Even though their oven was a different model # than my oven the part they replaced that made it work again was the same as mine. I didn't have the ability to do all the testing they did but the symptoms were exactly the same. so without delay i ordered the part from APP received it in 2 days installed it in about an hour and boom, my oven works again. The part is pretty expensive but so was this oven, so i bit the bullet and got it up and running.
