Product review (1 stars): Nothing but overprice troubles.
We installed this or very similar combination oven during kitchen remodel. One nice feature that it takes less space then two separate appliances and have one control panel for both. We have not have problems with oven cleaning (and we've done it multiple times) but in general this appliance was nothing but trouble. The bottom oven is fine, it is functional and holds temperature well. It has thermometer that can be put into the poultry/meat and cook until poultry/meat reaches desired temperature, takes any guessing out of the recipe.

Now the troubles. The microwave can be used as microwave but do not try convection features of top microwave they do not work and if you cook something in top microwave for real, you'll never been able to clean it. Given that you can buy convection oven for $400 and microwave for $100. You overpay ridiculous amount of money for having these two combined. And they are poorly combined to say the least.

The spring inside microwave door has failed 4 times, once a year I buy new one from sears parts, disassemble the door, replace it and next year it breaks again. One day the glass on the bottom oven door just all over sadden without anyone being in the kitchen cracked into small pieces and fell on the floor. Looking at the design of the handle, it is clearly flawed. Each time you open the bottom oven it puts some bending force on the glass in the door, eventually glass give up.

This appliance is the end of my (and my kids) relationship with KitchenAid. I'll never buy anything made by KitchenAid and if asked will recommend to stay away from anything with KitchenAid label.
