Your GE Monogram oven's design with only a heating element on the top is likely due to its specific function as a broil or broil-only oven. Broiling is a cooking technique that utilizes direct radiant heat from the top heating element to quickly cook and brown the surface of food. This design choice caters to the specific needs of broiling, which requires intense heat from above to achieve the desired texture and appearance of the dishes. Broil-only ovens are distinct from conventional ovens that have both top and bottom heating elements, which are designed for general baking and roasting tasks where even heat distribution is essential. In broiling, the top element's proximity to the food allows for efficient and rapid cooking, creating a seared and caramelized exterior while preserving the juiciness inside. The absence of a bottom heating element in your GE Monogram oven is a deliberate choice made to optimize broiling performance. This design simplifies the oven's construction and functionality, making it more focused and energy-efficient for its intended purpose. Including both top and bottom heating elements in a broil-only oven could lead to unnecessary complexity without providing significant benefits for broiling outcomes. If your culinary needs extend beyond broiling and involve baking, roasting, and other cooking methods that rely on even heat distribution from both directions, you might want to consider using a conventional oven with both top and bottom heating elements. Such ovens are versatile and can accommodate a wide range of cooking tasks. However, for achieving perfectly broiled dishes with a delightful crispy top, your GE Monogram oven's top heating element is designed to excel and provide outstanding results.
