Spa PC Boards: Printed circuit boards are similar to your pc computer board. The chip is programmed to operate a certain way and turns components on/off at certain times and for certain reasons.

Over the years many have asked why a board will fail. Sometimes the failure might be caused simply over time such as internal components failing and some even causing damage to other components. So boards look perfectly good yet will not operate or at least, correctly. Some simply have components on board that fail making the board not operate. Brownouts, blackouts, voltage surges and spikes can cause damage to your spa's board.

Over the years some have tried to change only the "chip" on the board to see if that solves the problem. The success has been limited but if the board looks perfectly fine, it could be the solution. More often you are simply trying to fix the problem in the wrong way.

Most if not all boards have settings. Easiest way to configure a new board to work is match such things a "jumpers" from the only to new. If you look at the boards you will see the jumpers.

FYI: It always makes sense to "ground" your body by touching something metal that is properly grounded. This will avoid any chance of a static charge damage to the new board.
