Before you buy — quick checklist

  • Confirm your control system is a VS511 or 511SZ — this board is not universal across Balboa product lines
  • Locate the part number printed on your existing circuit board and verify it matches G1960 before ordering
  • Check whether your system is a 2-speed pump setup — this is an expander board designed specifically for 2-speed configurations
  • Inspect the existing board for visible burn marks or damaged traces to confirm the board is the failed component, not the pump itself
  • Verify your spa's wiring harness connectors are compatible with this board before installation

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