Before you buy — quick checklist

Confirm your existing board's part number is exactly 6600-766 — check the label on the board itself, not just the control pack
Verify your J400 series spa runs a 1 or 2 pump configuration — this board does not cover 3-pump setups
Diagnose the root cause of failure before replacing the board — check for tripped breakers, blown fuses, and failed components upstream that may have damaged the original board
Inspect the control pack enclosure for water intrusion or corrosion damage that could damage the replacement board if not addressed first
Have your spa's serial number available to cross-reference compatibility with Sundance if there is any doubt

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