If your Bosch oven is burning food, the oven may be running too hot or heating unevenly. The most likely cause is a failed bake element. During normal operation, the bake element should glow red hot, so inspect it for holes or blisters and test it for continuity with a multimeter. Replace the bake element if it has no continuity. A burned-out broil element can also cause an oven temperature problem, especially if it does not glow red hot or shows visible damage. If both heating elements test good, a defective Bosch oven control board, main control board, or oven control board may have a failed relay and may not send voltage to the heating circuits correctly. A faulty temperature control thermostat can also make the oven run too hot, causing food to burn easily, and the thermostat must be replaced rather than repaired. Disconnect power before testing or replacing parts. Enter your Bosch oven model number to find the exact replacement bake element, broil element, thermostat, or control board for your appliance.
01 - Bosch 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 - Bosch 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.
