Thermador Refrigerator control panel not working
If your Thermador refrigerator control panel not working, start with the parts that fail most often: the user control and display board. Press every button and note which ones respond; if some buttons work but others do not, the user control/display assembly is the likely culprit. If the whole dispenser system is dead, the dispenser control board is more likely, but if only one dispenser function fails test that component first. A nonworking or blank display points to the display board after you confirm it has power. Loose or damaged wire harness connectors between the panel and control boards are another common cause and are easy to inspect. On models where the controls live in the dispenser front panel, a failed front panel assembly can mimic control board failure. Finally, check incoming power, outlet, and breakers before replacing parts. If you need a replacement, enter your model number at RepairClinic.com to see the exact user control, display board, dispenser control board, wire harness, or dispenser front panel that fits your refrigerator.
01 - Thermador Refrigerator User Control and Display Board
To determine if the user control and display board is defective, try pressing the buttons on the control panel. If some of the buttons work, but others do not work, the user control and display board might need to be replaced. Additionally, if the display is not working, check the power to the user control and display board. If the user control and display board has power, but it isn’t working, replace it.

02 - Thermador Refrigerator Dispenser Control Board
The dispenser control board governs most of the functions of the dispenser system. If only one dispenser part is not working, it is probable that an individual part has failed. In this case, test each of the dispenser components before testing the control board. If the entire dispenser system is not working, the control board is more likely to be at fault.

03 - Thermador Refrigerator Display Board
To determine if the display board is defective, try pressing the buttons on the control panel. If some of the buttons work, but others do not work, the display board might need to be replaced. Additionally, if the display board is not working, check for power to the display board. If the display board has power, but it isn’t working, replace it.

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.

05 - Thermador Refrigerator Dispenser Front Panel
On some refrigerator models the user controls are part of the ice and water dispensers front panel. If none of the control panel buttons are working, it's probable the main control board is malfunctioning. However, if some of the buttons on the control panel are still functioning, it's more likely the unit's user control and display is faulty. If this component is sold as part of the dispenser front panel, the entire assembly can be replaced.
Highly Likely
06 - Incoming Power Problem
Ensure power cord is fully inserted into a regular electrical outlet and the outlet is supplying power. Check fuses or circuit breaker if needed. It is best to keep the refrigerator on it's own dedicated circuit and not to use a ground fault receptacle which can interrupt power to large appliances.
Highly Likely
