Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

27" Wall oven combo rep[acement

Fran NC 9/8/2020

Love the oven, works great. I easily installed it myself, but I could not get the oven door back on.I called GE, they sent a tech by and after a while he got it on, works fine. Don't remove your door! I needed a white 27" unit and GE still makes one, glad I got it. Had to wait a while for delivery.

Gramps01 7/29/2020

This was a replacement for a previous GE double oven. This model appears to have improved upon the former model. Controls are easy to learn. We were concerned about the reorientation of the microwave door; however, we found that the new design was not a problem.

Oven design is deeper by 1/4" than specification

JohnVT12345 7/27/2020

I finally decided to replace my 20 year old 27" GE wall oven and microwave combo after a few fixes during the past 12 months. I decided to go with JK3800DHWW and expected the quickest installation. Since there was no floor model available locally, I downloaded the installation manual and carefully checked all dimensions (height, depth, and width). Once the new oven was delivered and measurements were made, it became obvious that folks at GE did not measure the depth correctly. They forgot to include the depth of screw heads in the installation manual. This oven requires a depth of 23.5 inches instead of 23" as specified. Please fix the installation manual so that the next customer can avoid any unexpected surprises.

Takes FOREVER to PREHEAT!

lmcphersonk 6/2/2020

We had to purchase this combo to fit our cabinets. Microwave door comes down in front, NOT to the side (like the last one) which makes it impossible to wipe splashes on the back and top of the microwave. Glass turntable vibrates as it turns. Cooling fans run for a long time AFTER food is done so it is confusing to hear the beep to alert you food is done. Oven takes forever to preheat. Also design is strange in that when it is installed it is not flush to area surrounding it (not cabinet). There is 1" gap in front of oven/micro unit and the doors, so I had to fabricate a piece to fill in the gap.

too many buttons

kathycat 3/26/2020

This oven looks great, love the large micro-wave, but you have to push too many buttons to get what you want. , No way to push in exact time like under 15 seconds, o r next would be 30 seconds

Inconvenient!

al1944 1/22/2020

Overall the product is attractive and seems well made. One complaint is that unlike other microwaves that I have had, this one goes into a "cooling" mode after cooking that is often one or two minutes which is inconvenient. The door to the microwave opens down which makes is difficult for a short person to reach into it to reach the food. Most microwaves open to the side allowing you to get closer to it making it easier to reach in. The microwave is also a little noisy.

REPLACED OLDER UNIT OF A DIFFERENT BRAND

DocBev 1/9/2020

We do no like the fact that the Microwave door opens down. It is hard to lift things over the door. Our former appliance opened to the side. The oven takes about twice as long to heat up as our former unit.

Jim65123 12/4/2019

The controls arrangement is well organized and messages are clear. Almost no need for the manual. I would suggest some more options on tone volume besides just on and off for us old people that don't hear so good.

non-intuitive interface

sourdough baker 9/18/2019

We purchased this as a replacement for another GE microwave/oven combination wall unit. This one has much less user-friendly controls. Most functions take about 5 button presses, plus knob turning. Our old one had very clear actual buttons, and most functions took 2-3 button presses. It works fine, but learning to use the controls has been frustrating so far. In ordere to figure some things out I had to read the entire manual. for exmaple, setting the clock--there's a paragraph in the manual about the clock which tells you the clock functions, but not how to set them. The fans in both oven and microwave are very quiet. Unfortunately, the end of cycle beeps are also quiet. I haven't used it yet, but I expect the proff funciton will be useful for me.

Better design and simpler control

TySac 9/4/2019

This GE 27" Built-In Combination Microwave/Oven has better design and bigger interior dimensions for both microwave and oven due to the control panel is located at the top instead of the right side.of the unit. Also the control panel is simplified into one for both functions. Good design, sleek and modern look! We love it.

GE wall oven and microwave.

Hess127 7/6/2019

Purchased GE unit to replace a 25 year old unit that came with the house when we built the home. It has the same rough cut dimensions but the interior of both ovens are larger. The cut out for the unit is the same as the old one but the new unit is larger, less tolerances and heavier. So far the unit is working well.

Good Oven....With One or Two Exceptions

Geppetto III 5/30/2019

We had a built in GE oven for 203 years and were happy with it. This one fit exactly into the opening so we bought it. BTW, the old one was still working, it just got a bit dirty over time. The new unit is great with 2 exceptions. The lower wattage causes it to take 50-75% longer to bring it up to temperature. The second is the microwave oven human interface. I found the old one much easier to use for short, simple zaps.

Disappointed replacement for previous GE combo

NotAFan123 4/24/2019

I like my previous GE microwave combo wall oven over this replacement. But for matching the cutout (with slight 1/4") wider opening modification, I don't see the value of cost added for the microwave. Most annoying is the undersized fonts for display, the unintuitive programming, slow preheat times and awkward microwave door opening down instead of sideways. Also microwave use results in subsequent noisy and confusing fan turned in for 'cooling'. Not a fan of the front glass doors either.

Not appropriate for the elderly

cal girl 2/8/2019

This is a very nice looking oven/microwave. We bought it for my 91 year old mother to replace her old built in oven. I wish we hadn't - The controls are way too technical and confusing for her; however there don't seem to be any new appliances with OLD FASHIONED controls. She is completely frustrated in attempting to use this appliance. The microwave door pulls down and is too high for my mother.

KarenJo 1/30/2019

I really enjoy the Microwave and how spacious it is; and the fact that it has a very sleek look. And the oven is fantastic. I thought that I would not like baking with electric; but I like it more and more. I love having the "pad" on top and not on the side. Makes it so much easier for me. Keeping it clean is a breeze.
