Ovens feature heavy duty metal knobs for temperature changes and cooking modes. A combination wall oven is the most versatile cooking option for those who want to customize their oven suite. The lower oven is a standard wall oven, while the upper oven option is up to you. Depending on your cooking habits and lifestyle, you can choose from an upper steam oven, speed oven, or microwave. The telescopic rack moves smoothly and supports heavy dishes and casserole pans with ease, making it effortless to pull out the racks. Broil mode uses intense heat radiated from the upper element and delivers the perfect char, sear, and grill without the mess. It is perfect for meats and bubbling crusts on casseroles. Convection Multi-Rack has a third heating element and a fan (regular Convection only has two heating elements) evenly circulates air around the cavity so you get consistently even golden results.
