Before you buy — quick checklist

  • Confirm your existing board's part number — locate the label on the current board and match it to 59187-02 or CTR-BP100G1-SR before ordering
  • Verify your spa's model and manufacture date to ensure this board revision is the correct replacement
  • Check that your topside control panel is compatible with this board — a mismatched panel can cause communication faults
  • Inspect all wiring harnesses and connectors before replacement — a failed board is sometimes caused by a damaged connector, not the board itself
  • Rule out a tripped GFCI or breaker as the root cause before replacing the control board

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
