A:Answer Hi Susan - Thanks for continuing to make GE Appliances a part of 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 30" over-the-range models will work as a replacement for your existing 30" over-the-range model #JVM150G001. Check out GE® 1.9 Cu. Ft. Over-the-Range Sensor Microwave Oven Model #:JVM7195SKSS with an easy-clean, dark gray enamel interior with steam clean option. If you have any additional questions, do not hesitate to ask, we are happy to help at GEAppliances.com! Sue
