  • Confirm your existing board's part number is 33-0024B-R4 before ordering — revision numbers matter

  • Confirm your existing board uses JST cable connections — mismatched connectors will prevent installation
  • Inspect the existing board for visible burn marks or failed components to confirm the board is the root cause
  • Check that the replacement board revision (R4) matches or supersedes your current board revision
