A:Answer This model would make a great addition to your home. All 30" Over-the-Range Microwaves are approximately the same width and are designed to fit into a 30" wide cabinet opening. Therefore, any of our current 30" Over-the-Range microwave models will work as a replacement for an existing 30" Over-the-Range microwave model. When replacing an Over-the-Range microwave, the mounting bracket included with the new microwave should be used since the mounting bracket is specific to each model. The new screws, bolts and exhaust adapter should also be used. -Don@GEAppliances
