When a Caloric range vent hood touchpad doesn't work, start by checking how many buttons respond. When some keypad buttons work but others do not, the touchpad is the most likely cause and may need replacement. If none of the buttons respond, the user control and display board or main control board could be defective, but control boards are often misdiagnosed. First confirm that the vent hood has incoming power by checking the circuit breaker or testing an accessible outlet with a small appliance. If power reaches the hood and the touchpad is separate from the control board, replacing both parts may be the best repair. A defective control board is less common, but it can cause the range vent hood control panel to stop responding even when the wiring is intact. Before testing or replacing parts, disconnect electrical power and use a meter only if you are comfortable doing so. Enter your Caloric range vent hood model number to find the exact touchpad, user control and display board, main control board, or control board replacement part for your specific appliance.

02 - Caloric 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 - Caloric 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.
