Product review (1 stars): Engineering Fail - Do not waste money
We purchased the newest model of this unit in December 2012.  We were told that the cooling fan size  had been increased due to overheating problems.  While it may have fixed the problem, now it just sounds like a whistling tea kettle in my kitchen.  The unit is in the same cabinet as my previous Jenn-air ovens (used for 22 years) and the noise level is the same in the cabinet or when pulled out of the cabinet by the authorized repairman sent by KitchenAid.

ALSO - the upper oven is supposed to be a choice between convect and bake mode.  The convect fan stays on in both modes all the time.  I was originally told that it would shut off when the oven reached temperature - it does not.  The note I got from an escalated complaint review was that the sound depended on installation and 'owners expectation' and that the fan would run for even heating.  I believe that is called convect and I wanted standard baking.  Also, there isn't even a convection fan in the bottom oven.  The entire explanation made no sense to me.

This oven looks lovely, but until they fix the fan problems and figure out how to offer a true bake/convect option do not waste your money.
