Wall Oven: Why won't my wall oven broil?

In an electric oven, the bake element at the bottom of the oven and the broil element at the top of the oven provide the heat for baking and broiling. Replace them if they're broken or if the oven isn't heating properly.

The electronic oven control (EOC) board governs the timing and execution of oven functions such as baking and broiling. It's usually in the control console and often has a digital clock on the front of its housing. Replace the electronic control board if it doesn't light up when it's supplied with electrical power, if it doesn't operate properly or doesn't properly send voltage to the bake or broil element (in an electric oven) or burner (in a gas oven).

Most gas ovens have a glow-bar oven igniter and a safety gas valve. Those components are connected in a series-type electrical circuit. When the glow-bar oven igniter is hot enough to safely ignite the gas, the safety gas valve opens. Replace the oven igniter if doesn't glow, or if it glows but doesn't get hot enough to open the gas valve. Some ovens have a separate igniter for the bake burner and the broiler burner, which operate on the same principle.

Some wall ovens have a relay control board that's separate from electronic control board. The relay board has electrical relays that control voltage going to major loads such as the bake element or a surface element, based on signals from the control board. Replace the relay control board if it fails to properly control voltage to a component.
