When selecting your spa circuit board, please remember that it is critical that you do not base order on appearance but rather by part number or description. Master Spas Circuit Boards can look identical, but are not interchangeable or compatible with other units or spa components other than that which they are programmed for. The part number and description on a Master Spa Circuit Board can be found directly on the circuit board.
