A small amount of frost in the freezer of the RFG297AARS is normal, since each time the drawer is opened, warmer air enters carrying moisture that freezes on the cold surfaces inside the compartment. While Samsung freezers do have heaters in the walls that cycle on periodically to prevent frost build-up, this does not necessarily prevent the moisture from condensing on the packages or plastic bins. To help reduce the amount of frost on packages, keep the drawer closed as much as possible.
