"Frost-Free" refers to a feature commonly found in refrigerators and freezers that prevents the buildup of frost inside the appliance. This technology uses a fan to circulate air, maintaining a consistent temperature and reducing humidity, which helps keep food fresh without the need for manual defrosting. In a frost-free freezer, the automatic defrost cycle periodically warms the evaporator coils, melting any frost that may have formed. This water is then drained away, ensuring that the storage space remains clear and usable. This feature is especially beneficial for those who want to save time and effort in maintaining their appliances.
