Hey buddy I know that this thread is a little old about 10 years but I'm sure some somebody will run into the same issue . I had the same issue trying to program this board look like the board is unresponsive I even put the old board in to make sure that the keypad is working. Eventually I realized that the instructions were a little off it tells you that you need to hold a refrigerator alarm door button and the freezer down button and then release the freezer down button and wait 3 seconds actually you need to hold alarm door and freezer down button for 3 seconds and then release and then it immediately goes into programming mode Then followinstructions as they are in the sheet
