Thermador Range vent hood touchpad doesn't work

When your Thermador range vent hood touchpad doesn't work, start by testing several keypad buttons. If some buttons respond while others do not, the touchpad is the most likely cause and may need replacement. If the entire control panel is not responding, the user control and display board or main control board may be defective. Control boards are often misdiagnosed, so check the more common touchpad problem first. Next, verify that the Thermador range vent hood is receiving incoming power. Check for a tripped circuit breaker, or test the wall outlet with another small appliance if the vent hood plugs into an accessible outlet. If power reaches the controls and the buttons still do not work, the control board is a likely failure point. Some Thermador range vent hoods have the buttons attached directly to the control board. If your model has a separate touchpad, replacing the touchpad and control board together may be recommended. Enter your model number to find the exact replacement part for your Thermador range vent hood.

04 - Incoming Power Problem

Vent hoods are typically hardwired to the circuit breaker box, but they can also be plugged into a wall outlet behind the cover panel. In either case, it may be difficult to test the incoming power to the vent hood without removing a large cover panel. If the unit is plugged into an accessible wall outlet you can plug another small appliance into the outlet to confirm there is power. If you cannot access the incoming power connection easily, confirm the circuit breaker suppling power to the vent hood has not tripped.

05 - Thermador Range Vent Hood Control Board

Most range vent hood control boards have the buttons attached to the board. If you've determined that power is reaching the board, then it's likely the control board is defective and will need to be replaced. If there is a separate touchpad, it would be a good idea to replace both the control board and touchpad at the same time.
