Very Nice Oven

Submitted by Joechef - 9/17/2017

Replaced a 20 year old Thermador oven, smaller fit heightwise but width was great.. oven performs very well with easy gliding racks.. oven comes with a pizza stone which I haven't used yet... Good lighting in the oven and even heating, a little long for preheating but overall very happy with my purchase. Very hard to find a 24 inch oven that fits perfectly, i found that most European brands the oven was shorter for the space.

Best oven ever!!

Submitted by Mrs loves to cook - 8/28/2017

This oven replaced one from 1987. Kitchenaid was THE one. It heats quickly, convection cooks/bakes evenly, is self cleaning...what more could I want ? It's a beautiful addition to my kitchen and I love it.

Good looking oven!

Submitted by Mr Scott! - 8/18/2017

Bought this along with a microwave to replace a 24" Double oven. Hard to find 24" appliances these days. This worked out great. It's convection too! We've only used it a couple of times, but it worked well. Easy to install, has some cool features we're still learning about. It feels and looks like a good quality appliance. Hopefully I'll get 23 years out of it like the Whirlpool it replaced :) So f you are remodeling an older kitchen (like me) and can't go 27", this is your oven.

Works Great!

Submitted by Kathy's New Convection Oven - 8/8/2017

I bought this convection oven about a month ago and it is working great! I really love the digital timer and clock! Not to mention it cooks great! I have cooked baked Parmesan chicken and roasted potatoes at the same time and it cooked evenly and tasted great! This is my first time having a convection oven. And I would recommend it to everyone!

Excellent product

Submitted by Daveodonn - 6/21/2017

This is a beautiful full featured wall mounted oven. I have installed it myself and the install manual was all that was required. It fit into the cabinet opening of an older unit that had died. From start to finish I completed the install in 1 hour and 10 minutes. We have used it at least a dozen times and have been extremely pleased with the features and the resulting products.

Yes, I recommend this product

Awesome Broiler

Submitted by Recman25 - 6/17/2017

Fantastic oven all around. One complaint is the sheet metal vibrated on the top of the unit making a horrific noise. Had to remove the oven from the wall and tighten up the sheet metal screws which fixed it. Some type of cushion between joints at factory would prevent this.

Yes, I recommend this product

Perfect fit!!!

Submitted by Now We're Cookin' - 6/9/2017

What a pleasant surprise! We bought this unit to replace an old featureless oven. The KitchenAid fit within the install constraints (24", brick surround, cabinets, etc.) perfectly. Once installed we quickly felll in love with the features and performance. We could not be happier! Thank you KitchenAid!!!

No, I do not recommend this product

unreasonable preheat time and fan never turns off.

Submitted by BobIt - 4/24/2017

It looks great and is pretty easy to operate except for the inordinate amount of preheat time and it goes into a preheat mode again when you open to place food in oven.

No, I do not recommend this product

Really like the oven

Submitted by Rita, I like to cook - 4/13/2017

I bought this oven without a lot of research because I was replacing my refrigerator and wanted them to match. I did not have a large space to it needed to be compact. I have been very pleased. It does everything I wanted and more. I did not expect a proofing setting but it is great. Using the electronic settings was easy to master(my old one was mechanical turn dials) and I really appreciate the prompts that are programmed in. The temperature settings seem accurate, and like have three racks. I have not used the self cleaning or pizza stone yet.

Great oven, lousy installation instructions.

Submitted by A baker - 3/3/2017

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.

Yes, I recommend this product

True Convection Oven

Submitted by Andrea at Finn Land - 3/2/2017

KitchenAid needs to rework their instruction pamphlets. I can't say that all the oven's features are great because we can't figure out how to use them all. Hire a good product writer and graphic artist to produce an instruction pamphlet that is useful.

Great Oven,,,Great Features

Submitted by Marcie the Italian cook - 11/26/2016

Just put in the 24 inch single as I live in a duplex with limited space. Convection Roasted my Turkey yesterday with a try at delayed time setting. This is a little tough to do but all in all when I finally got the mechanism to work it cooked fantastically.!!! Love the looks and the interior is strangely larger than my old oven which was a standard single oven. Love the 3 racks. Cannot wait to bake and see how my traditional recipes come out....

Submitted by Chris - 11/25/2016

I bought this to replace my old in the wall oven that was 42 years old. I want an standard oven plus a convection oven. I have used both types and am very pleased with the results. The convection cooked the pies and browned them very evenly. It is easy to clean the outside plan.

Yes, I recommend this product

Meets the requirements

Submitted by Rosie - 11/11/2016

This is the only 24" convection oven on the market that was available from my local distributor, so I was somewhat apprehensive, not able to do much comparison shopping. The oven turns out to be exactly what I was looking for, and food cooks quickly and evenly in it. It takes a long time to preheat, and the keypad is a bit difficult to operate (it takes quite a bit of pressure to make the buttons respond), but otherwise it is doing the job I need.

Yes, I recommend this product

Love this oven, but...

Submitted by Barb - 10/12/2016

I love using this oven. The temps are even and it warms up quickly. Even the Convection feature is easy to use; I am not a computer user! The only but is that the first time I used the Se;f-clean feature, the oven blew two fuses and went dead, leaving the door locked, no way to get into the oven. It has been two weeks since that happened. With re;lpacement parts not readily available I am still without use of the oven. Good thing I have others!

Yes, I recommend this product


Submitted by Sparky - 9/27/2016

This oven replaced our 30 year old Chambers. It is a pleasure to use this oven - the convection roasting cycle makes our meats taste so much better. Wish we had purchased it sooner! Looking forward to doing our Thanksgiving turkey.

Good Oven - Missing Key Advertised Features

Submitted by Fenoy - 8/24/2016

Review is on the KitchenAid KOSC504ESS 24 inch single electric wall oven. Oven appears to be a well-built and high quality. Oven replaced a decades old KitchenAid (KEBS147DWH4) convection oven. Haven't owned the oven long enough to have any feeling about durability. The oven cooks very well and it has both the standard convection and conventional cooking methods. The internal oven thermometer seems to be very sensitive - sensitive to the point that is you place a frozen item in the oven the internal temperature of the oven will drop returning it to the preheating mode. The new oven does not have a probe which is viewed as a major plus. Probe on the older model was a constant source of irritation, frustration, and alarms. With the new oven the blast of hot air when opening the door is much reduced over the older model - a major plus. No complaints regarding cooking with the oven other than the preheating time appears to be at least twice as slow as the older version. Our major complaints regarding this oven are what I consider to be false advertising on KitchenAid's part. Despite what's shown on KitchenAid's website the oven does not have the EasyConvect Conversion System. If this feature is important to you you'll be solely disappointed with the oven. Another much missed feature is the convection "Roast" feature which was available in our older KitchenAid oven and which is listed as a specification in KitchenAid's specification chart as well as in the operator's manual - it simply isn't an option. The convection modes incorporated in the over are Bake, Broil and Proof. There simply is no longer a "Roast" convection feature as stated in the specifications and the owner's manual. Also confusing is that the specification list "Star K" and "Temperature-Senor Baking" yet a search of the operator's manual does not seem to list these "Features." Overall mostly pleased with the oven except for the false information provided by KitchenAid.

Crazy about my Kitchenaid Oven!

Submitted by Happy Kitchenaid owner - 7/24/2016

I have had my Kitchenaid oven about 4 months and couldn't be happier! It is beautiful and stylish. So far, it cooks like a dream. I was initially concerned, before I got it, that it might be a convection only oven. Not so! It serves as either a regular oven or as a convection oven. It cooks so evenly and precisely "by the book". It is a wonderful addition to my kitchen and I love it. The only drawback that I have found is that the oven is just a tiny bit less deep than my previous oven. This is only because the fan feature is located on the very back wall of the oven and it juts out a tiny bit into the oven cooking space. This has been of no consequence, except when I try to place an extra large round pizza pan in the oven. I was still able to bake my pizza, anyway. It was just that the pan barely fit. I am so happy and excited about my new oven, though, that this small thing really does not matter. Do not hesitate, if you are thinking of purchasing this oven. It is fabulous.

Do Not Open Oven Door

Submitted by Lynn - 6/18/2016

When I open oven door to move pans, the oven powers up to get the temp back up. Blows hot air over food and burns it. Best solution is to use convection and oven light to check for doneness.

Love My KitchenAid Wall Oven!

Submitted by Dunkjam - 3/28/2016

I Bought my wall oven sight unseen by special order. I had an unusual size oven that I had to replace. I knew I wanted a KitchenAid oven because that is the only brand I will purchase. It cooks evenly and is very easy to use. The only reason I just gave it a 4 star rating is the fact that the preheating time is very slow. I do not know if this is due to the EPA standards, but it does not heat up as fast as my old oven. I love the interior lighting, it allows me to see the food easily as it cooks. It has a self=cleaning oven which is a must for me. I would recommend this oven highly.
