In most electric ovens, the broiler and baking functions cannot be used simultaneously. Typically, the broiler and the bake functions use different heating elements and modes of operation. The broiler uses the top heating element to produce intense heat from above, while the bake function uses the bottom heating element or both the top and bottom elements to provide even heat throughout the oven cavity.
Using both the broiler and bake functions at the same time could result in uneven cooking and potentially damage the oven or create a fire hazard. It's important to consult your oven's user manual or contact the manufacturer to confirm the specific capabilities and limitations of your oven model.
If you require simultaneous broiling and baking, you might want to consider using a separate countertop broiler or grill alongside your oven.
