This oven repair guide explains how to replace a hidden bake element in a wall oven. In some cases, you might see visible damage in the element, but the element can seem intact and still not heat. Replace the bake element with a manufacturer-approved wall oven part if the oven doesn't heat in bake mode or if the bake element is damaged.
Although the video below shows a range, this basic repair process works for replacing the hidden bake element in many Kenmore, Frigidaire, Electrolux and Samsung wall ovens.
