If your Thermador oven is burning food, cooks too hot, or food burns easily, start by checking the bake element. A bake element with holes, blisters, or no red glow may be damaged and can affect how the oven heats. Test it for continuity with a multimeter and replace it if it fails. Next, inspect the broil element for visible damage and test it for continuity, since a failed broil element can contribute to an oven temperature problem. If both elements are working, the oven control board is the next likely cause. Its relays send voltage to the bake and broil circuits based on your settings and sensor input, so a defective board may send incorrect power to the heating components. A faulty temperature control thermostat can also cause the oven to run hot, and the thermostat must be replaced rather than repaired. Less commonly, the main control board or oven control board may be defective. Disconnect power before testing or replacing parts. Enter your Thermador oven model number to find the exact bake element, broil element, thermostat, or control board for your range.
01 - Thermador Range/Stove/Oven Bake Element
When the bake element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the heating element has burned out, it will be visibly damaged. Inspect the heating element for holes or blisters. To determine if the bake element has burned out, use a multimeter to test the element for continuity. If the bake element does not have continuity, replace it.

The broil element may have burned out. When the broil element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the element has burned out, it will be visibly damaged. Inspect the broil element for holes or blisters. To determine if the broil element has burned out, use a multimeter to test the element for continuity. If the broil element does not have continuity, replace it.
The control board has relays that send voltage to the bake and broil circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components.
04 - Thermador Range/Stove/Oven Temperature Control Thermostat
The temperature control thermostat regulates the broiler temperature. If the thermostat is defective, it may fail to heat the broiler element. The oven thermostat is not repairable—if the thermostat is defective, you must replace it.
05 - Thermador Range/Stove/Oven Main Control Board
The control board has relays that send voltage to the bake and broil circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components.
06 - Thermador Range/Stove/Oven Oven Control Board
The control board has relays that send voltage to the bake and broil circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components.
