If the heating element works, either the bake element is damaged, or there’s a wiring issue. The bake element is on the bottom of the oven and is the size of a pencil and black in color. This element typically connects to the oven by two screws. Remove both screws and pull the bake element out. Then attach a 240V circuit to the element terminal. Reconnect the oven to the power supply and turn the oven to bake. If the light comes on, the bake element is burned out, and you will need to replace it. Sometimes the food will cook partially even when the bake element burns out because the broil element in the oven is heating the food. If the light does not come on, you have a problem with the wiring.
