Getting to know your appliance
The fully automatic NO FROST system ensures that ice does form inside the freezer section, eliminating the need for defrosting. Food is frozen by a flow of cold air circulated by fans. The evaporator cools the air, and moisture condenses on it, then evaporates. The freezer section and frozen food remain ice-free.
