Before you buy — quick checklist

  • Confirm part number X801162 is printed on your existing PC board — do not rely on model name alone
  • Verify your spa's control pack model is MS501X before ordering
  • Check for visible burn marks or failed components on the old board — if the cause of failure isn't resolved, a new board may fail again
  • Inspect incoming power supply and breaker before assuming the board is the fault
  • Note all wiring harness connector positions or photograph before removal — incorrect reconnection will damage the new board

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