GE built-in 27" convention oven (JKP18)

I have the same oven and the problem is probably the control panel not the circuit breaker. I'm having the panel replaced next week for the 3rd time in 8 years but, you can find it on the web at repairclinic.com for about $140. they also provide troubleshooting help and installation help. I've spoken with GE many times trying to convince them that my oven may have an assembly related problem but they don't want to hear about it. Just replace the part and avoid all the aggravation I've endured trying to get GE to take care of it.
Good luck

We are having the same problem but there is electric coming into the oven all the way to the panel but the panel will not work. Blank as above. So it seems it is the panel. 3/15/07

Chanski, Most likely the problem is with the circuit breaker, not with the oven. Your oven needs 240V (two legs, 120V each) to work. If one of the legs is missing you will have the oven light but nothing else. The first thing you have to do is to check the power from the circuit breaker. It must to be a double breaker for the oven and it suppose to be about 120V between ground and each leg and about 240V between legs themselves. It is better to call a professional to do it for you due to very high risk. Gendos...post back
