Product review (4 stars): Would buy again and again
We bought this for our new home and I can't say enough good things about it.  I do agree with the previous poster that the fan seems to come on during both regular cooking and convection but it doesn't bother me in the slightest and although I do find items cook a bit quicker in my top oven then my bottom, I have not had anything burn on me and have been very pleased with the results of all my baking/cooking.  I love being able to have double ovens in a regular oven slot and I find the top oven can hold almost everything (just not a turkey or ham - tall things) so we cook almost everything in that oven and I belive it saves some cost of electricity.  The only problem I have run into is that when I ran my self clean it would not unlock after the cycle was complete and the oven cooled down, I had to wait 2 months for replacement parts however as I had only run the clean on the bottom oven, I could still use the top oven while waiting for the parts.  My repairman said that the worst thing you can do for your oven is run the self clean cycle, it is very hard on the oven and often causes problems, he recommends not using them on any oven as they will most likely shorten the life of your oven.  So since then I havce just used easy off oven cleaner and it works like a charm.  I also LOVE the griddle in the middle of the stove, we cook eggs, quesadillas, pancakes, etc. on it and just wipe it down with a paper towel afterwards, it's great!  Love, love, love this oven.
