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 and 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.

Raised my electric bill


Since getting this oven my electric bill went up substantially. I uses to be lower usage than the average home and now I have higher usage. The only change is oven. It takes so long to heat up Also be aware that the microwave is very large which is good but had I realized I might have considered getting the convection oven option even though it is much more expensive. But I rather have something else anyway

Great features and looks great


After our 20-year-old reliable microwave/oven combo finally stopped working altogether we started looking for our next unit. I read numerous reviews and decided on this GE model due to the positive reviews. Indeed this unit performs very well exceeding our expectation. Here I would like to address one critical drawback mentioned by some reviews: the microwave cook time certainly is adjustable One easy way that we use is to use the express 30 seconds feature and then turn the dial to adjust the time to the desired duration. On the other hand indeed the chime is too quiet and drowns into the background noise easily. I wish its a bit louder. Overall this is a great microwave/oven unit. Highly recommend.

Efficient oven


We ordered a microwave/oven all-in-one built-in August 2017. Although it took several calls for the installation company to coordinate delivery the installer was courteous and efficient. The oven is large bakes well. The microwave has many features but Im not crazy about the large dial that must be pushed 4-5 times to start whatever Im microwaving.

No happy with it


My od one died. I dont like this one as much. The oven takes at least 20 minutes to heat up. The timer is only good for microwave or oven. the controls are not user friendly. For instance you can microwave for 15 seconds 30 seconds one minute but nothing in between and it takes severl adjustments to get to start. Also the finish make look nice but every time you touch it you leave a mark and have to wip it off.

Just installed and the fit was perfect in my custom built cabinet. My only complaint is the knob because it has to be turned and pushed too many times for your desired setting. Ive always used broil to heat my ovens quicker so I dont know how long it takes for the bake unit to heat up.

Poor design compared to a previous model.


Both oven and microwave cook fine. But compared to our 17 year old previous model there are three big differences that after 10 months still bother me so it is not a matter of just getting used to it. 1 The cooking element in the oven is no longer located on the bottom of the oven but rather BENEATH the bottom of the oven unseen. It makes for easier cleaning but longer preheating times. It takes 12 minutes to heat to 350 degrees. 2 The microwave oven door no longer opens to the side but rather straight out just like the oven door. This is a HUGE impediment to cleaning the microwave for me. I am 52 and have to stand on a footstool to reach the back awkwardly lowering my head to see what Im doing. Very much a hassle. I used to clean the old microwave several times a week. Now it just gets filthy and I clean it once a month which is a shame because the inside is a shiny when clean stainless steel-like material that looked beautiful when new and when clean. This is really ironic because GE made the lower oven easier to clean but the microwave harder to clean. 3 The controls are what bug me daily. Here are my major complaints. aThere is only ONE express cook button which is for 30 seconds the old one had seven - one for each minute up to 6 plus a 30 seconds. Now there is a DIAL involved. If you want to heat something on high for 3 minutes you need to take the following steps: push Microwave push the dial to confirm Cook by Time which shows on the display along with other options then turn the dial eleven times to go from 15 seconds to 3 minutes in 15 second intervals. Its PREPOSTEROUS. Sure you can try to turn the dial fast to 3 minutes not stopping at each interval but then you risk going past your intended target and then have to back track. Or you could push Add 30 seconds six times. b There is only one timer the old one had two. I miss having both when I have something in the oven and also need to time something Im doing over on the range like turning chicken cutlets or timing rice. c The detested dial is also used to set the timer and it is set up poorly for me because most of my cooking is for less than an hour. But the way the timer is designed you need to turn the dial past the hours/minutes choice to get to minutes/seconds. To set the timer for 35 minutes here is the process: push Timer On/Off then turn the dial to Minutes/Seconds and push the dial to select that option turn the dial 35 times you can turn it quickly and just slow when you get to the 30s and push to select 35 as the number of minutes then push to select 0 as the number of seconds. Why an option for seconds? Is there any home chef who needs to be so precise? d The timer and preheat tones are not loud enough. The timer will keep beeping until turned off but I often miss the preheat notification because its only once. The volume can not be adjusted - the choice is either on or muted. Why would you want to mute it? Our previous version model JTP85BA1BB of this combo unit came with our model home when it was built in 1999. We had the microwave repaired by GE two or three times over the 18 years. But when it failed this time the GE repairman quoted something outlandish because the parts were no longer available. We just went ahead and ordered this newer version sight unseen from our local appliance store. I wish I had known how inconvenient this new version was and would have liked to find a carpenter who could do something with my cabinets so wed not have to buy a combined unit I also hated having to get rid of a perfectly fine oven just because the microwave died.
