The PreciseAir convection system of the GE Profile 30 in. Self-Cleaning Slide-In Electric Convection Range has a reversing fan that circulates heat and air throughout the oven to help you produce evenly browned and baked goods. The cooktop's tri-ring element gives you a choice of 12 in., 9 in. or 6 in. sizes and its bridge element combines 3 cooktop elements into 1 large cooking area that's great for griddles and gourmet pans. The range's self-cleaning system spares you the trouble and effort of scrubbing the oven interior.
