Before you buy — quick checklist

  • Confirm your existing board's part number is exactly 6600-499 — do not assume compatibility based on spa model alone
  • Verify your spa is a J300 series unit and note the specific sub-model from the equipment bay label
  • Check your electrical supply — confirm whether your installation is 120V or 240V before ordering
  • Inspect for visible burn marks, blown components, or water intrusion on the old board to rule out a deeper wiring fault that could damage the replacement
  • Document all wiring connections with photos before disconnecting the old board

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