A:Answer Not a guarantee. We thought this new item should have the same mounting profile as the installed Frigidaire Gallery microwave, buy it was not identical. The newer model required the mounting plate to be an inch lower than the existing mount. If going directly onto the wall, it should not be a problem, but we had backsplash right up to the existing mounting plate. This required us to remove one inch of ceramic backsplash. That was a very dirty task and required the use of a 3 1/2 “ blade circular saw, with a diamond tip blade and an Oscillating tool with a diamond tip blade. If you have to perform this task, here are some recommendations for doing this and not crack your existing tiles. 1) Place tape directly over the area to be cut and mark you line on the tape. 2) Adjust the saw to make 1/16” deep cuts with each pass, till you are through. 3) have a second person with a spray bottle of water spray the cutting area to try and minimize the dust.
