Hi, we have. GE Profile oven and just replaced the temperature probe, however we still have the same problem. In Convection mode it works fine, however, in Bake mode, the oven heats to the desired temperature, but does not hold that temperature and often looses about 50 degrees in a very short period of time. I noticed above, that there was mention of possibly replacing the Control Board. Can anyone let me know if that fixed the problem, or anything else I should check or do first?

Dear Guest.
What is the compete model number of the oven?
How did you measure the temperature in the oven?
Thank you.

I am wondering if Nealu... has anything further to report on what caused his problem. I believe I have a similar problem with our stove, the only difference is that ours has been like this from new but the warrantee representative refused to do anything about it. He concluded the temperature was too high and suggested we lower the temperature 20 degrees. He measured this after he turned the oven on and it had come up to temperature. He never stayed around to see what happens to the oven over time. I would possibly replace the control board if this would fix it but I don't want to spend that kind of money with no positive results.
