Common symptoms this part fixes

Before you buy — quick checklist

  • Confirm your existing control box part number matches ACM0952 or 0612-221041-605 before ordering
  • Verify your spa operates on 60Hz — this is a 60Hz-specific unit
  • Check that your spa is a Wellis brand system — fitment is not confirmed for other brands
  • Rule out a failed temperature sensor or flow switch before replacing the control box, as those can trigger the same HH and OH faults
  • Photo your existing wiring harness connections before disconnecting anything

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