Please don't type in all caps. Its considered yelling. I was looking at these two models too. I'm leaning away from the KitchenAid (assuming you are looking at the new Architect II models) because they are much lower in power (watts) in each of the modes (bake, broil, convection). For the price difference, the Monogram seems to me a better choice.

I agree that not being able to turn off the convect fan in the bake mode is just plain silly, but that is the way this particular model works. The noise problem isn't that something is loose -- we have had an authorized service man out twice and it is the fan/air noise, not anything rattling. I've talked to the Whirlpool people and it seems that the convect fan issue is really planned into some of their units. I think it's ridiculous and I hope they carefully identify that this is the case. Some people may not care, but I wanted a clear choice between bake and convect. Other than that, though, these ovens were just too noisy to keep and KitchenAid has agreed to take them back.

Hi Don ... sorry to hear you are experiencing the noise problem. I must say we have Never had a problem with this oven...I am very happy with it...No problems at all. I know there is another post in here with the solution. I may not express or describe this properly because it has been a couple of years but...it had to do with a loose coupling or bent screw...something like that at the back of the fan. .. I hate to put this on you...but I am sure you will find more info here. If I can think of something more specific I will certainly let you know...However....definitely get to Whirlpool....they certainly know about it... and if memory serves they will send out a replacement fan...

Here is my report as promised: I made my favorite chocolate chip cookie recipe, and brought a batch of cookie dough balls to the store. The KA demo lady never did show up, so I just experimented on my own. First I turned the oven on regular bake at 350ú to see if I could hear the fan. The air conditioner fan in the store was very loud, and I could hear no oven fan at all on regular bake. I got impatient waiting for preheat, so turned the oven to convection bake. I could hear the convection fan, but it was very quiet, especially given the air conditioning noise. Convection bake preheat went much faster. Maybe ten to fifteen minutes. I proceeded to cook the two cookie sheets in the oven, on the 2nd and 4th racks. The recipe is normally 375ú for ten minutes, so I did 350ú for 9 minutes. I should also say that I used my regular flat, air insulated cookie sheets, which some say not to use with convection, as they keep the bottoms from browning as much as they would with a regular cookie sheet, which is supposedly not necessary with convection. The cookies came out perfectly, rose well, crunchy outside, chewy inside. The cool down fan continued after I turned the oven off. Still very quiet. However, the salesman told me that the demo oven is over four years old and that it was the oven that came out after that which had all the noise complaints. He also said that they had all been corrected in the factory for all new ovens, not by a complete redesign, but by whatever running corrections they are able to do as they go along. So I am still not 100% confident that I have heard the real thing. However, I am going to go ahead and order the oven, as the fan on this one was completely unobjectionable, at least so far as I could tell, and the cookies were excellent. Two other things the salesman suggested: Use the bottom oven preferentially when using only one oven, as it is further from the electronics and will improve the control board life span away from the heat. also, Never use the self clean, no matter what the oven, because the extreme heat is so bad for the electronics. He recommended instead heating a shallow, jelly roll type pan of water with baking soda on the bottom of the oven for an hour at 300ú, then wiping down the whole with a cloth. Not as effective as self-cleaning, but safer. That's all folks!
