Replaced a 27 year old GE oven so I was definitely overdue for an upgrade but this model is AMAZING The microwave is huge and powerful cooks quick and defrosts evenly. The oven is also a generous size and I love the steam clean option. Oh and did I mention - its a beautiful piece too goes great with our new quartz countertops and other stainless appliances. Extremely pleased with this appliance and highly recommend.

mixed reviews

3/13/2018

I love the appearance of this microwave / oven. This unit replaced my previous GE oven that we had for 20 years. The old unit was in good working condition but we remodeled our kitchen and wanted new appliances. We decided to purchase GE because we never had any problems with the previous appliances. My review is as follows: The door of the microwave does not open to the side like the old unit instead it opens down and this prevents me from reaching the back of the microwave to clean it. Also to heat up something you need to push the bottom too many times. they need to simplify this. Regarding the bottom oven the preheating time takes much longer than our old unit did. I wish GE would consider making these changes in future models to make it more user friendly. Overall I am pleased and hope this unit lasts as long as the old one.

3/2/2018

Like the product but the microwave door is a real problem. I am 52 and it will be a real problem for me to reach the back of the microwave to wipe it down. Also it is a problem for me to reach some things. I never had this problem with a door that opened to the side. Also Im afraid the electronics will not last. I feel this was designed by a man who would have no trouble reaching the back of the oven.

2/24/2018

I bought this combo to replace a 1990s version that was in the house we bought. I must confess that I bought it because it was guaranteed to fit in the space the old one came out of. I read some reviews but expected it to just be a regular appliance. Well its been three months now and I LOVE both the oven and the microwave. I cook and bake a lot. The quality of these appliances is exceptional. The oven bakes everything right. The temperature control is terrific. And the microwave once youre used to the features is a treat to use. It reheats and cooks perfectly. If I had known how much I was going to love this I would have also bought a GE range just for the oven.

Wonderful Oven

1/27/2018

I bought this oven 2 months ago and love it The microwave is much larger than my old microwave and does a great job. I didnt think I would like dialing the cook time and temperature but I like it much better than the touch pad. The lower oven is roomy and cooks evenly. I love the light coming on when I open the door. Another great feature is the steam cleanup of spills. Love not having to clean whole oven. This is a great product

This microwave/oven is absolutely amazing. It is so much bigger than the original one and fits into the same space. The microwave is huge and heats so quickly that I have to remember to shorten the time needed to heat or cook something. The oven is also wonderful. The dials and keypad are so easy to use and understand. Both my husband and I cook and we are delighted with our new purchase. It also looks great too.

Appealing Unit

12/9/2017

My last GE wall unit lasted 31 years so this unit will probably outlast me. Overall it seems to well made and works well however it does have a number of usability issues that you should be aware of. For some reason they decided to use a very low contrast value for the fonts on the touch screen. I suppose this gives it a cleaner look but at times its difficult to read the labels on the control surface. Theres no back light so if the lights are low or theres glare on the screen its very difficult to read. If you have anyone in your family with poor or low vision they will have trouble seeing the touch screen. It would have been great if they had included a option to turn on back light for the panel. The panel also shows finger marks easily. It also seems they opted to keep the user interface simple so many of the functions are nested in several sub menus. For example on my old unit I could use an express key to turn on the microwave for 1 2 3 4 or 5 minutes with one button push. Now it takes numerous pushes and dial turns to achieve the same result. I wish they had included one programmable key so you could save a favorite time setting. The chirp alarm sound on the microwave cannot be adjusted.

Better than expected

12/5/2017

We have had this unit for about 2 months and I must say that I like it better than I thought I would. Speciffically the microwave and the door opening from top to bottom instead of from the side. Took a little getting used to the controls versus our old GE but like them just fine. The only thing that would make it better is a louder alarm for timer/ finished cooking as you can barely hear it. Overall a nice unit.

12/3/2017

I do not like the timer for microwave or setting of oven temp for baking. I thought it was a touch pad device and it is not. It is my fault for not checking this out. I just thought that today everything was touch pad. To set the temps and time you have to turn a knob for choosing temps and then pushing it to set. It is no big deal--I just prefer touch pad. If I had known this I would have chosen another model.
