A:Answer Hi John60- We certainly appreciate your loyalty! JVM6175SKSS is a great choice with sensor cooking controls. 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. 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. 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. Also, the microwave ovens are designed for adaptation for the following three types of ventilation: 1.
Outside Exhaust (Vertical – Delivered from factory in vertical position). 2. Outside Exhaust (Horizontal). 3. Recirculating (Non-vented ductless). All over-the-range microwaves can be vented to the outside using an equivalent total of 140 feet of rigid 3 1/4" x 10" rectangular or rigid 6" round ducting. Enjoy! Sue
