Thermador Oven shuts off on its own

When your Thermador oven turns off by itself, the touchpad is the most likely cause, especially when some buttons respond intermittently or not at all. A faulty touchpad can make the oven shut down or stop accepting commands, so replacing the Thermador range/stove/oven touchpad may solve the problem. A blown thermal fuse is another possibility if the oven overheated. Test the fuse for continuity with a multimeter. If it has no continuity, replace it because a thermal fuse cannot be reset. If some touchpad buttons work while others do not, the touchpad and control panel may be defective. If no buttons work, the oven control board is more likely at fault. Also check for an incoming power problem, including a tripped circuit breaker. Loose or burnt connections, failed relays, or a defective control board or main control board can also cause the oven to shut off during use. Before ordering, enter your Thermador oven model number to find the exact replacement part for your appliance. Disconnect power before testing or replacing components.

01 - Thermador Range/Stove/Oven Touchpad

If the oven turns off on its own, determine if some of the buttons on the touchpad respond intermittently or not at all. If so, it's likely the touchpad is faulty and should be replaced.

02 - Thermador Range/Stove/Oven Thermal Fuse

If the oven gets too hot, the thermal fuse trips to shut off power to the oven. If the thermal fuse has blown, the oven will not heat. However, this is not a common occurrence. To determine if the thermal fuse is at fault, use a multimeter to test the fuse for continuity. If the thermal fuse does not have continuity, replace it. The thermal fuse cannot be reset—if the fuse has blown, it must be replaced.

03 - Thermador Range/Stove/Oven Touchpad and Control Panel

If an oven won't turn on, it's possible the touchpad and control panel is defective. One way to help confirm this is to determine if some touchpad buttons respond while others don't. If some of the buttons still work, then it's quite probable the touchpad and control panel is faulty and requires replacement (if none of the buttons work, a defective control board is more likely the cause of the oven not turning on).

04 - Incoming Power Problem

If an oven turns off on its own there could be an incoming power problem. Verify the circuit breaker hasn't tripped.
Common

05 - Thermador Range/Stove/Oven Control Board

The board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.
Less Common

06 - Thermador Range/Stove/Oven Main Control Board

The main control board sends power to all the components in the stove. If the control board connections are loose, or burnt, or the control board is turning off on its own, one of the relays or other components may be bad and the control will need to be replaced.
