Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

Before you buy — quick checklist

  • Confirm your control pack is a Balboa unit that uses part number 30270-2 — check the label on your existing transformer or control board
  • Verify your spa runs on 230VAC — this transformer is not compatible with 115V systems
  • Count the pins on your existing transformer plug and confirm it is a 6-pin configuration
  • Inspect the PCB mount points on your control board to ensure mechanical fitment matches before ordering
  • Visually inspect the control board for additional damage — a failed transformer can sometimes indicate an upstream short or board fault

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