I've been using my new KA KBHS109 built-in convection microwave oven as a microwave and love it. Tonight I decided to try the EASYCONVECT option to bake banana bread. I followed the instructions, put the metal tray on the turntable, pressed EASYCONVECT, pressed 1 for bake, pressed 325 for temp, pressed 50 for minutes, pressed start, waited until it preheated, inserted bread in stone loaf pan when told to, pressed start. It worked for 3 minutes and then just shut off. Tried two more times. same thing. Don't know what to do now. Anybody have this and used it? Thanks.

I assume that the MW is on a shelf that is the bottom of that cabinet, right? How about putting a fan blowing down and out from the back of the cabinet? I think if you look for a cooling fan in an electronics catalogue, you will find one you can install there. If you draw the air out from behind and below the MW, fresh, cooler air will be drawn in from the smaller spaces around the MW. This could work. They make laptop tables/trays with these fans. Here is a link that might be useful: look at these

Browning happens at a temperature above 350. You don't need a broiler for that. As Weedmeister said, a broiler will do things faster, but a higher temperature will also aid browning. You don't need a broiler for crisp chicken skin. You do need the right amount of moisture. If there's too much moisture, it'll stay soft. OTOH, a slightly moist environment will aid crisping. The moisture comes from the air in your kitchen, and the chicken itself, plus whatever else you put in. I regularly make crisp skinned chicken in a convection-steam oven. You might need 360-375 degrees, however. I use 360 out of habit because it said so in a recipe, so I don't know if there's any magic there. The thing about browning with a broiler is that because the heat is coming from above, the top will brown first and/or faster than the rest cooks. This is useful for a variety of things you might want to cook. But you can have browning and crisping without it. The big difference with a speed oven is that you have combination modes where both heated convection and microwaves are used, and possibly other elements such as the broiler. This allows you to cook and brown on the outside as well as cook from the inside out (microwave) all at the same time, which makes the food done sooner. Some Speed ovens are more microwavy, others are more oveny, and most will allow you to customize the settings so you can change that balance. Most convection/microwaves let you do one or the other at any particular time. If you're buying it specifically for pizza, you might look into the freestanding pizza cooker appliances too. Pizza is usually cooked over 500 degrees, and not under 450, and is generally best on a thermal block like a pizza stone, or cast iron pizza pan. Some of those pizza makers will also do any kind of other snacks that aren't tall, such as sandwiches, burritos, etc. A speed oven seems overkill (and a lot of money) if you don't want to use the speed features, but if you have the money and want to clear the counter, and if your choice has the broiler and can deliver an appropriate temperature for the pizza, it might work well. If by "pizza" you mean teens warming up a pre-made one caring more about speed than quality, either oven would work, though speed ovens have an edge in speed as well as quality. The counertop pizza maker might take less time than either.

I had a GE Advantium OTR oven in my previous kitchen, and regretted it. That's because I bought the 120v version. The 240v version was more expensive so I bought the 120v instead. Big. Mistake. It was little better than a regular MW. The exhaust was extremely loud, and I know that OTR MWs have very loud exhausts, but this was even worse. If I had to do it over, I'd have bought the 240v Advantium. My friend has the 240v version, and it is quite a good oven. Whether it is worth the extraordinary expense is a personal decision. The exhaust is still extremely loud. (BTW, for my current kitchen, I have an exhaust hood, and a very good countertop Panasonic MW on a shelf, not built in--a cinch to replace if need be). Here is a link to the 240v OTR Advantium. You may be able to find a refurbished one or older model for much less. http://m.us-appliance.com/psa9240sfss.html?gdffi=1e2f1f21161340a5bb92274135f25ab7&gdfms=3080405D6EC748B4B8EC30A749067AC2&gclid=CjwKEAjw6e_IBRDvorfv2Ku79jMSJAAuiv9YDDDHI-RAWdc_dePLchA-aYNwty24eu7dwculLGODQBoCMObw_wcB
