How to fix it

  1. Verify the part numbers of the installed UI and ACU against the model's tech sheet.
  2. Order the correct part number if a mismatch is confirmed.
  3. If both boards are genuine and correct, unplug for 5 minutes and retry.
  4. If F2E2 persists with verified-correct parts, replace the user interface board.
  5. If still failing, replace the main control board.
