Wall Oven : Won't bake properly

If the oven isn't heating to the baking temperature you set-it's too hot or not hot enough-the oven temperature sensor could be malfunctioning. Or the problem could be with the oven control board, which controls oven functions. Some wall ovens have a relay control board that's separate from electronic control board. The relay board has the electrical relays that control the oven elements or burners. A stuck relay on the relay control board can prevent the oven from baking properly.

Wall ovens that have dial controls use an oven control thermostat to control oven temperature. You may be able adjust the thermostat to fix a baking problem when oven temperature is off by 15 degrees or less. If the actual temperature differs from the set temperature by more than 15 degrees, you may need to replace the oven control thermostat. (Note: The temperature adjustment limit varies among models. Some models have controls that allow you to adjust oven temperature up to 30 degrees in either direction.)

A failed bake or broil element in an electric wall oven can cause baking problems. A weak or damaged bake element won't heat the oven properly. If food isn't browning, the broiler element or burner might be at fault; many ovens activate boiling briefly to brown the top of baked dishes.

Many gas wall ovens use a glow-bar igniter to light the bake burner. A weak igniter may light the burner during the preheat mode but won't continue to ignite the bake burner properly in the bake mode. You may need to replace the igniter if it fails to light the oven burner consistently.

Replace the wall oven control thermostat

Replace the wall oven control thermostat

The oven thermostat is a temperature-controlled switch that controls heating inside the oven. Replace the thermostat if it doesn't maintain the oven temperature incorrectly, if it fails to turn on to the oven burner to heat the oven, or if it fails to turn off the burner when the oven is at the set temperature.

Replace the wall oven igniter

Replace the wall oven igniter

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.

Replace the wall oven temperature sensor probe

Replace the wall oven temperature sensor probe

The oven temperature sensor probe detects the actual temperature in the oven cavity. Replace it if it's not detecting the temperature properly, in which case the oven doesn't maintain the temperature you set. A complete failure, in which the sensor probe doesn't detect any temperature at all, usually triggers an error code on the electronic oven control board.

Replace the wall oven electronic oven control board

Replace the wall oven electronic oven control board

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).

Replace the wall oven relay control board

Replace the wall oven relay control board

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.
