If your Broan range vent hood touchpad doesn't work, first press several keypad buttons to see whether any respond. When some buttons work but others do not, the touchpad is the most likely cause and may need replacement. If the entire control panel is unresponsive, the user control and display board could be defective. The main control board is another possibility, especially when none of the touchpad buttons work. Before replacing a control board, verify that the range vent hood has incoming power. Broan range vent hoods are often hardwired to the circuit breaker, although some plug into an outlet behind the cover panel. Check for a tripped breaker or test an accessible outlet with another small appliance. If power reaches the controls and the buttons still do not respond, the Broan range vent hood control board may have failed. On models with a separate touchpad, replacing the touchpad and control board together may be recommended. Enter your model number to find the exact replacement touchpad, user control and display board, main control board, or other part for your specific Broan range vent hood.

02 - Broan 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 - Broan 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.
