Thermador Refrigerator not running
If your Thermador refrigerator seems dead and the display or lights are off, start by treating this like a control-panel problem: a failed dispenser control board is often the culprit when the fridge display is completely dead, so inspect the board for burn marks and visible damage first. Next check incoming power by confirming the plug is fully seated, the outlet is supplying power and no breakers or fuses have tripped. A failed user control and display board can produce the same symptoms, so test or swap that if the dispenser board checks out. Also verify wire harness connectors between the panel and control board are tight and undamaged, and try a simple power reset after a surge by unplugging or switching the breaker off for a few minutes. The main control board is a last resort; it does fail but far less often than the other parts. If you need replacement parts for a specific Thermador model, enter your model number on RepairClinic.com to find the exact control board, display board, or harness that fits your refrigerator.

Highly Likely
02 - Incoming Power Problem
Ensure plug is tightly pushed into a regular electrical outlet and the outlet is supplying power. Using a ground fault outlet for a refrigerator is not recommended. Confirm that no circuit breakers have tripped or fuses have blown.
Highly Likely
03 - Thermador Refrigerator User Control and Display Board
If the refrigerator display appears completely dead, it's possible the user control and display board has failed. You should inspect the board for any burn marks and replace it if it appears damaged.
Common
04 - Disconnected or Damaged Wire Harness
The wires from the control panel to the control board may be loose or have become disconnected. Make sure the wire harness connectors are tight. A damaged wire harness will need to be replaced.
Common
05 - Power reset
After a power surge or power outage, refrigerator operation could be temporarily affected. Full operation can sometimes be restored through a power reset by either unplugging the appliance's power cord for a few minutes and then plugging it back in or switching off the circuit breaker for the refrigerator then switching it back on.
Common
06 - Thermador Refrigerator Control Board
If nothing is working on the refrigerator, it's likely the control board is defective. However, this is almost never the cause. Before replacing the main control board, test all of more commonly defective parts. If none of the other components are defective, consider replacing the control board.
