It could be one of the switch that has failed or it could be a problem in the board.
You will need an ohm meter to check the switches.
If you do and checking on the board make sure that you use the wiring diagram.
Read the notes on the diagram because the board for the dispense converts the AC voltage to DC voltage.
The wiring diagram should be in an envelope stuck to the bottom of the fridge behind the kick plate.
