A:Answer Hi Rose - Thanks for reaching out to us! We are sorry to hear your microwave JVM1750EP2ES needs replacing and apologize for any inconvenience this has caused. All GE 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. However, 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. We certainly appreciate your loyalty. If you have any additional questions, do not hesitate to ask, we are happy to help at GEAppliances.com! Sue
