Using the Maytag MMV6178AA 1.7 cu. ft. Over-The-Range Grill Convection Microwave Oven is like having four ovens in one! This is a unit which implement several brand new technologies to give you a highly advanced cooking experience. It allows you to choose between combination speed cook, convection bake or roast, or microwave mode. In combination speed cook mode, the microwave combines halogen light and microwave energy to cook three times faster than a conventional oven. The convection bake and roast mode uses an integrated fan which shortens cooking time by circulating hot air uniformly around food, for more even cooking results. It has a grilling function which browns and crisps food quickly and easily. The normal, microwaving elements use 950 watts of cooking power with ten levels so you have absolute power and control over the cooking process.
