Great kitchen oven

by: Mary's place

Submitted: 11-10-2020

We have used the oven several months now and we get everything we expected and more. [This review was collected as part of a promotion.]

Great oven, lousy installation instructions.

Submitted: 11-10-2020

Great build quality. Overall installation was straighforward. But the door has to be removed to install the lower vent cover. The instructions are woefully inadequate in describing how to position the door hinge latches and how to remove the door. Saints be praised for YouTube, others have blazed the trail. Instructions also don't show/tell how to reinstall the door. Once you figure it out it's simple. Touch pad controls are finicky, have to get used to the lag and how to press them. It's slower to preheat than my 30 year old wall oven that had rotten gaskets. Overall a good value and nice oven.

Beautifully made product

by: Lucius

Submitted: 11-10-2020

There is an exhaust fan that stays on for a period when the oven is turned off. It would have been advantageous for KitchenAid/Whirlpool to have given some information about this in the user pamphlet. Information about what? The fan's use, and the length of time it remains 'on' after the oven is turned off. I have never had an oven with such a feature, and it was sort of startling to hear this somewhat load fan after the oven's usage. [This review was collected as part of a promotion.]

Expensive garbage

by: Not convection.

Submitted: 11-10-2020

Not worth the money. You have to make adjustments to every recipie to not overlook. No convection. Wife loves the look of it... but other than the hat it is expensive garbage. [This review was collected as part of a promotion.]

Died after doing self cleaning

Submitted: 11-10-2020

Purchased for my mother 2017 Christmas gift She really enjoyed using it. Work great UNTIL we did the self cleaning January 2018 . During the self cleaning it shut down the screen went black no clock nothing and the door remained locked. Did a google search of ( Oven shuts down during self cleaning ) one of the fist results was KitchenAid. Have not had the oven even a Month . Getting it repaired under Warranty . The self cleaning was one of the features my mother requested I am now afraid this will be a reoccurring problem.
