LG's innovative Orbit Round Cavity optimizes interior space within the same footprint. At 16" in diameter, the turntable can accomodate extra large round serving dishes. Another benefit is the round cavity is easier to clean because there are no hard to reach edges. SmartWave technology provides a constant level of power when cooking, reheating and defrosting any food. The benefit is that the food is evenly cooked through-out without burning the edges. The monitor door design includes an ergonomic horizontal keypad.
