Summary: We purchased the KEBS279BSS on March 7 of 2014 and had it delivered and installed May 2015 as part of a kitchen remodel. In mid March 2015 after using the self cleaning feature on the top oven the convection fan would make a louder than usual noise when running during the bake cycle.
Summary: Unfortunately myself and the other reviewer bought this at the same time, so I did not see her review until it was too late. I purchased it in April 2013, and started using in July 2013 when kitchen remodel completed. Immediately there was a loud buzzing when using either the top or lower oven.
Summary: I am now on my third oven KEBS279BSS in a year. Kitchen Aid has admitted back in April 2013 that there was a problem with the electronics and they expected a fix once it got out of litigation. They have provided new electronic boards and new ovens and it still does not work.
Summary: This double oven is everything I could wish for in ovens. And they are simple to operate, the controls work very logically, the ovens do everything they are supposed to do! Wish I hadn't waited so long to get them.
