The refrigerator drawers unit is designed with an automatic defrost system. However, on colder settings, some frost may build up. On top of this, the more humid the ambient conditions are, the more additional frost can be created.

Keep the drawers closed as much as possible and avoid opening the drawers unnecessarily to minimize frost build-up.

If frost is preventing the drawers from closing properly, you may need to power the unit off until the frost melts (possibly up to 24 hours). Use a soft absorbent towel to dry the unit.
