If your Wolf range vent hood touchpad doesn't work, start by checking whether some buttons respond while others do not. When only certain keypad buttons fail, the touchpad is the most likely cause and may need replacement. If none of the buttons work, 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 vent hood is receiving power. Check for a tripped circuit breaker, or test an accessible wall outlet with another small appliance. Wolf range vent hoods may be hardwired or plugged into an outlet behind the cover panel, so disconnect power before removing panels or testing internal components. If power reaches the board but the controls remain unresponsive, the Wolf range vent hood control board may need replacement. A separate touchpad and control board may be best replaced together when both are involved. Enter your model number to find the exact touchpad, user control and display board, main control board, or other replacement part for your specific Wolf range vent hood.

02 - Wolf Range Vent Hood User Control and Display Board
The user control and display board may be defective. Control boards are often misdiagnosed—before replacing the user control and display board, first check all of the more commonly defective parts.
The main control board may be defective. To determine if the touchpad is defective, try pressing some of the keypad buttons. If some of the keypad buttons work while other buttons do not work at all, the keypad is likely defective. If none of the keypad buttons work, the main control board may be defective.
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 - Wolf 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.
