NoFrost Technology

Automatic defrosting system eliminates manual defrosting.

  1. How it works: A fan circulates cold air while a heating element periodically melts frost on evaporator.
  2. Water drainage: Melted frost water evaporates automatically; no drip tray to empty.
  3. Benefits: Consistent temperature, no ice buildup on walls or food, energy efficient.
  4. Maintenance: Ensure air vents inside freezer are not blocked by food packages.

WARNING! Never attempt to manually scrape ice or use sharp objects inside freezer. If frost appears despite NoFrost, contact service.

Energy Saving Tips
