Common symptoms this part fixes

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

  • Topside panel unresponsive or dead
  • Buttons not registering when pressed
  • Display blank or showing garbled characters
  • Spa won't switch modes from the topside
  • Intermittent loss of panel communication with control pack
  • Panel backlight failed but control pack is functioning

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your control pack is specifically the Balboa AX40 — check the label on the control pack box, not just the panel
  • Verify your existing panel's part number or SKU matches G8940 before ordering
  • Inspect the ribbon cable or panel connector on your current unit to ensure the replacement connector style matches
  • Diagnose whether the issue is the panel itself or the control pack — a dead panel on a functioning pack is the correct use case for this part
  • Check for corrosion or water intrusion at the panel connection point before installing the new panel

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