If your Thermador range is producing a burning smell, stop using it until you identify the source. A defective temperature control thermostat is the most likely cause listed for this symptom. The thermostat regulates broiler temperature, and when it fails, it may affect the broil circuit and require replacement. Next, check the Thermador range control board, main control board, or oven control board. These boards use relays to send voltage to the bake and broil circuits, and a failed relay can create an electrical burning smell from the stove or prevent the heating components from operating correctly. A shorted bake element is another likely cause. Look for holes, blisters, or other visible damage, then use a multimeter to test the element for continuity. Finally, inspect the broil element for damage and test for continuity between each terminal and the outer case. Continuity to the case indicates a shorted element that must be replaced. If your Thermador range smells like burning, disconnect power before testing electrical parts. Enter your model number to find the exact replacement thermostat, control board, bake element, or broil element for your specific Thermador range.
01 - 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.

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.
03 - 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.
04 - 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.
Sometimes, if the heating element burns out, it can short out to the inside of the oven. Often, if the bake element has shorted out, it will be visibly damaged. Inspect the heating element for holes or blisters. To determine if the bake element has shorted out, use a multimeter to test the element for continuity. If the bake element does not have continuity, replace it.
If the broil element is shorted out. Often, if the element has shorted out, it will be visibly damaged. Inspect the broil element for holes or blisters. To determine if the broil element is shorted out, use a multimeter to test the element for continuity. If the broil element shows continuity from the terminals to the outer case, this indicates that it is shorted out. If the broil element is shorted out, replace it.
