When replacing your spa or hot tub circuit board, it’s important that you go by part numbers on the circuit board and not visual appearances. The current part number on a spa circuit board can usually be found on a white sticker located directly on the circuit board. Only buy based on this part number. Do "NOT" purchase a hot tub circuit board just because it looks the same because there is a programming difference from board to board even though they can look identical
