Before you buy — quick checklist

  • Confirm your spa is a Wellis brand unit — this is an OEM-specific part
  • Locate the ACM1191 part number on your existing converter before ordering
  • Verify the existing converter shows visible damage, burn marks, or failed continuity before replacing — converters are sometimes misdiagnosed
  • Check that your Wellis spa uses the IN-MIX system architecture — not all Wellis models share the same control components
  • Document all wiring connections with photos before removing the old converter

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