A:Answer Hi Vinny, that answer is correct because I had the older the Advantium, it was probably 17 years old never had a problem with it. The problem was there was no parts available to fix the existing microwave. I had to first have an electrician take the 220 line down to a 110 line because it was more expensive to buy the 220, I originally ordered a trim kit for the microwave but that did not work because it’s really not for the ADvantium no difference in the size if I remember correctly. I eventually found the trim kit myself because the salesman did not know about it. This was an ongoing problem for a few months trying to get the right microwave for the cabinet. The kit is actually an accessory drawer to fill in the space in the height of the microwave otherwise it does fit the width. It was challenging but finally it works. If you want I can send you a picture of what it looks like the biggest problem was it did not come in black because my GE oven is black so it’s stainless steel and that’s the only choice. I hope this answers helpful it will be easier for you if you don’t have the cabinet and get a different microwave but I like my Advantium and I am happy Do you have finally filled the hole in the wall correctly. For me it was a five month ordeal by the time we finally got everything situated. But at least now they know what to do to fill the gap.Good luck and happy new year if you have any other questions feel free to ask.
