A:Answer Hello. Thanks for reaching out! 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 30" over-the-range models will work as a replacement for an existing 30" over-the-range model. Just note that, 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. Model JVM6175EKES would make a great replacement. We know that you will make a great choice, and should you have any additional questions, please reach out to us!- Kianna@GEA
