I happen to own a KA superba myself.....recently remodeled a kitchen and had one installed. I watched the guy put it in....to remove it from the cabinet, open the door...look on each side of the oven frame and you should notice a stainless steel screw on each side...remove the screw and then remove the stainless steel piece (about 1 inch wide and sort of a trim piece) then you should see a couple of screws actually fastening the oven to your cabinet frame. Remove those and the oven will slip out. Also, I think you are correct about the humming coming from the transformer....my micro oven was making a humming noise while NOT in use and the repair guy found that we had a loose screw in the transformer....he tightened and now we are all set !!!

I have no idea how old it is; it seemed fairly new when we bought this house 6 years ago. I have no issues with mine. the fan seems to run for a long time / loud after I use it, but it isn't an issue unless you're sensitive to stuff like that. It has been a very reliable oven for me. Mine will go on Craigslist in a few months when I redo, so I hope I'm lucky enough to find someone like you who wants one ! Good luck, Anita Anita

Howdy all ... coming back to this to update on the LG range I recommended... Two things I'm not entirely thrilled with... 1. The knobs have a tendancy to "melt" on the bottom - the heat coming from the top oven distorts the bottoms of the knobs. Something LG is very aware of and will send out a replacement set without question, but still ... will have to replace them every 3-6 months? Ugh. 2. The oven doors - there is an open vent along the top edge. Within the first month something spilled and it's a not an easy thing to disassemble the door to get in there to clean any "in-between" mishaps. I think our old Maytag double-oven had a similar issue, but because the windows were more opaque, it wasn't an eyesore that required immediate disassembly & cleaning. What I'm more than a little peeved about ... not LG's fault ... my husband was DEAD SET against an induction top. No way, no how, had to be gas, period. He's not exactly the cleanest cook - lots of grease spatters (but the results are SOOO worth it!)... now he's constantly griping about how difficult it is to clean. "Maybe I should have looked at induction, I mean, all of the pots & pans we have are compatible..." DOH!!!!

We did end up going with the microwave drawer. I have mixed feelings about it. I soooooo much prefer it over the above the range one we previously had. It is SO convenient and so easy to clean. I love reaching down for food instead of above my head. And the mw itself works fine, very steady, no issues with food spilling or anything. It opens and closes slowly and smoothly. On the other hand, we don’t use a microwave for cooking, just reheating and such, and I’d like to reduce our use even further. For that reason I almost wish we’d just gotten a really small one and hidden it in a cabinet. But it is a very nice microwave and so much more ergonomically friendly (if that’s the best way to put it.) A couple of pictures for you. And I love my KA double oven. Definitely didn’t need anything fancier :)
