Before you buy — quick checklist

  • Confirm your existing board is labeled VS510SZ — do not order based on cabinet or spa brand alone
  • Verify the part number G1154 is printed directly on your current circuit board
  • Check that your control pack housing is a VS510SZ series unit, not a VS501, VS520, or other Balboa variant
  • Diagnose the board as the root cause before ordering — test topside panel, sensors, and wiring harness connections first
  • Document all wiring harness connector positions with photos before removing the old board

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