A:Answer Hi RDmicro- We certainly appreciate your loyalty! Thank you for making GE Appliances a part of your home. Yes, all 30" over-the-range microwaves are approximately the same width, and are designed to fit into a 30" wide cabinet opening. Each microwave comes with the mounting hardware (mounting bracket, screws, exhaust adapter), top and rear templates, and installation instructions needed to make installation a simple process. This makes choosing a replacement microwave easy. Model PVM1970SR1SS is approximately 29 7/8"W x 16 7/8"H x 15 7/8"D. Model JVM6175SKSS is approximately 29 7/8"W x 16 1/2"H x 15"H. If you are interested in the dark gray, easy-clean porcelain enamel interior with Steam Clean feature, we suggest our GE® 1.9 Cu. Ft. Over-the-Range Sensor Microwave Oven JVM7195SKSS. The Steam Clean feature generates steam to re-hydrate dried spills/splatters making cleaning easier. It is approximately 29 3/4"W x 16 1/2"H x 15 1/2"D. Keep in touch. With so many choices, we are always glad to help make your buying decisions a bit easier! SUEatGEA
