Before you buy — quick checklist

  • Photograph your existing circuit board and note the full model number printed on the board before removal
  • Confirm your spa's control pack enclosure is a BP20 series — check the label on the pack housing
  • Verify the MQBP20UX-BS suffix on your current board matches exactly, as Marquis uses multiple BP20 board variants
  • Check your spa's manufacture date — control pack revisions can change mid-production year
  • Isolate the board as the failure point before ordering — test topside cable connections and inspect for burned traces or blown components first

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