Before you buy — quick checklist

  • Confirm your existing keypad has an oval form factor — do not order if your current keypad is rectangular or round
  • Count the buttons on your existing keypad and verify it is an 11-button configuration
  • Check the cable connector on the back of your current keypad — verify it matches the J-400 series harness plug before ordering
  • Confirm your spa is a J-400 series model (check the equipment bay label or owner's manual)
  • Inspect the keypad mounting recess on your spa shell to confirm the oval cutout matches this unit's footprint

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