Gaggenau Range vent hood touchpad doesn't work

If your Gaggenau range vent hood touchpad doesn't work, first check whether some buttons respond while others do not. When only certain buttons fail, the touchpad is the most likely cause and may need replacement. If the entire touchpad is unresponsive, the user control and display board or main control board could be defective. Control boards are often misdiagnosed, so test the touchpad and confirm incoming power before replacing a board. Gaggenau range vent hoods are commonly hardwired, although some models plug into an outlet behind the cover panel. Check that the circuit breaker has not tripped, and verify an accessible outlet with a small appliance if applicable. If power reaches the vent hood but the controls still do not respond, the control board is a likely failure point. Models with a separate touchpad may require replacing the touchpad and control board together. Enter your Gaggenau range vent hood model number to find the exact replacement touchpad, user control and display board, main control board, or other part that fits your appliance.

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 - Gaggenau 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.
