GE presents an over-the-range microwave with convenient cooking features and powerful ventilation. Sensor cooking technology automatically detects the moisture level of foods and automatically adjusts cooking time and power accordingly. The result is delicious food cooked to perfection - no guesswork necessary. With weight and time defrost, defrosting frozen foods is just as painless. You can set your desired defrost time, or you can simply enter the weight of the food, and the oven automatically sets the optimal defrosting time and power level. The melt feature provides a perfect melting temperature for butter, caramel, chocolate and cheese, and with the "add 30 seconds" button you can add 30 seconds of cook time with the quick touch of a single button. Plus, the 300 cfm venting system removes smoke, steam and odors produced by your range, and the check filter indicator will alert you when to change the filter.
