A:AnswerI have no idea. GE does not give good guidance material with the purchase of the stove. Plus no instructions on using the oven air fryer and a few recipes to get familiar with it.
A:AnswerI too have 25" countertops and find this oven to fit very well. 1 1/4" of actual stove body and another 2 1/4" for the door for a total of 3" inches protrude. If my 240 amp plug-in was recessed in the wall. or on the floor the oven would slide all the way in fitting perfectly. As it is, I love it and do not notice that little inch it protrudes. And I LOVE the oven space I have.
A:AnswerNo. The vent across the back is part of the oven functionality. It has nothing to do with the cooktop. There is no mechanism to turn it on or off and the user manual tells you to make sure it is never blocked.
A:AnswerOrder you some Cerama Bryte and use the non-scratching scrubby that comes with it. Love the stuff and have been using it for years. Also remember, if you cook with dirty bottom pots, that can blemish your stove top as well. So maybe some steel wool for the bottoms of your fav skillets and pots and the above for your stovetop. My new stove came with no cleaners nor any recommendations that I can recall. If something spills on burner while cooking turn off heat immediately. After it's cool clean it as well as you can before using it again. Continuing to cook with a dirty burner can "bake it on" if you know what I mean.
