Before you buy — quick checklist

  • Confirm your spa's control pack label reads BP501G1 — photograph the existing board before removal
  • Verify your system uses an SR-series configuration — check the equipment bay label or owner's manual
  • Confirm this is a Platinum Spas USA model, not a Platinum Spas international variant
  • Check that your topside control panel is compatible with the BP501G1 board
  • Inspect wiring harnesses and connectors for corrosion or damage before install — a bad connector can damage a new board
  • Disconnect all power at the breaker and wait for capacitors to discharge before handling the board

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