SUNDANCE® SPAS | CIRCUIT BOARD 850 EXPORT SERIES | 6600-111

SUNDANCE® SPAS | REPLACEMENT CIRCUIT BOARD FOR THE 850 EXPORT SERIES | 6600-111

  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
