  • The panels from model 542 will not fit model BI-42UFD.
  • The BI-42UFD is a French door model, so two door panels are needed for the refrigerator.
  • New custom panels would be needed.
  • A new reduced height or extended grille will be needed, if used. See Classic Series (BI) Grille Height Options.
