Most of the time thier is a simple solution to this problem. Many times during shipping or installation the actual control board may become dislodged from the housing. If there is no clicking sound when the buttons are pressed then you must unscrew the top of the housing from the control board. There are snaps that hold the board in place. If the board became dislodged from these snaps then the buttons will not make contact. Just make sure the board is fully snapped in and your problem should be solved.
