Before you buy — quick checklist

  • Confirm your existing board's part number is exactly 52491 — check the label printed directly on the board
  • Verify your control system is a Balboa 1000LE series before ordering
  • Inspect for visible burn marks, corrosion, or damaged components on the old board to confirm it is the failed part
  • Check that your topside panel and sensors are compatible with the 1000LE system — a faulty topside can cause board failure if not also addressed
  • Document all wiring harness connections with photos before disconnecting anything

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