Summary: for the price, not great. Microwave seems to be low wattage and takes twice as ling to heat or defrost. Having small convection is nice. Microwave also has low clearance/height inside. Big oven seems to work well but takes a bit to warm up. Bought cooktop, oven and dishwasher so would all go together - mistake. Kitchenaid drawer also a huge disappointment.
Summary: i owned the kitchen aid steam oven and range - it would take volumes to describe the torturous 6 month experience but here is a synopsis: broken on arrival after 7 service calls and 6 months still not fixed kitchen aid refused to replace and so had to dispute the charge on my credit card - thank goodness i won this unit was $4,999.99 - never again kitchen aid. Had the same problem with my KA dishwasher purchased at the same time also replaced on my own dime.
Summary: We had this oven installed on December 1st 2008. It lasted 4 weeks before the magnetron and inverter went, rendering the microwave completely unusable. We called kitchenaid to get the appliance fixed, who sent a repair technician who diagnosed the problem but couldn't fix it. Kitchenaid then sent ANOTHER technician who then had to re-diagnose the problem. The second technician has been a nightmare since, unable to order correct parts and fix the problem at all.
Summary: Easy to install (did it myself - my daughters helped me lift it into place - it is heavy), easy to use, microwave works great, oven appearance is very clean. Cookies in 8 minutes on all 3 racks all baked evenly! One wish: would be better if a broiler pan were included - it is not. It must be ordered separately. Have not used the microwave broiler element or convection yet - but I'm looking forward to it.
Summary: We purchased this combo two years ago due to size limitations. I am a baker and a cook, the oven and the microwave are used daily. The microwave failed in 10 months, but was under the manufacturer's warranty. The magnetron was replaced but the repairman warned me and said, "get the extended warranty". Thank god I did. It failed again, 10 months later under the extended warranty. The repairman has been here 8 times and replaced every part and it still doesn't work.
Summary: My unit is a kemc387KSS, same thing only older. So far I have had the door hinges break after 3.5 years. A fuse blow. And the Megatron on the microwave go out at 5.5 years. I called A&E Factory Services every time. They get $129 for service call, so about $400 in service calls. And over $600 in parts. Total over $1,000. New $3,600.
Summary: Nice combination oven/microwave. Has convection function but I haven't taken the time to learn what I can do with this feature. (my 2 young kids and working full time nights just keeps me too busy) Looks great in the kitchen, surprisingly not too bad with smudges and fingerprints. HOWEVER, the most annoying feature is that the microwave keeps going on and on and on in the "cooling" function and it's very loud for a modern appliance.
Summary: Less than a year ago I replaced all my appliances with Kitchen Aid Brand Architect Series. I purchased the combination oven. We had used it about 5 times and decided to clean it and set the oven to the self cleaning. After that the oven is falling apart, the blue enamel inside is coming off every time we use the oven. I replaced a 22 year old whirlpool that was in perfect condition and never broke.
