A:Answer Hi JERZYGAL - The Upper Oven is not convection. The Upper Oven offers Bake (Traditional), Broil Hi/Lo and Warm. The Lower Oven offers Convection Bake, Convection Roast, Bake (Traditional) and Broil Hi/Lo. Also, if you need venting, check out GE® 1.9 Cu. Ft. Over-the-Range Sensor Microwave Oven JVM7195SKSS. Four-speed, 400-CFM venting fan system quickly removes smoke, steam and odors from the cooktop to keep kitchen air fresh and clean. Thanks for considering GE! SUE@GEA
