If your Bosch range vent hood touchpad doesn't work, the touchpad itself is the most likely cause, especially when some buttons respond but others do not. A defective touchpad can make the range vent hood controls not working or leave the control panel partially unresponsive. If none of the buttons respond, the user control and display board may be faulty. The main control board is another possibility, particularly if the touchpad tests good but the hood still will not respond. Before replacing an electronic part, check for an incoming power problem. Bosch range vent hoods may be hardwired to the circuit breaker or plugged into an outlet behind the cover panel, so verify that the breaker has not tripped and that power reaches the unit. If power is present and the buttons remain unresponsive, the control board may need replacement. When a separate touchpad and control board are used, replacing both may prevent repeat problems. Enter your Bosch range vent hood model number to find the exact replacement touchpad, user control and display board, main control board, or other part for your specific appliance.

02 - Bosch 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 - Bosch 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.
