Ensure door seals are clean and tight: Test by closing door on a piece of paper; if it pulls out easily, seals may need replacing.
Defrost food in refrigerator: Saves energy and helps cool refrigerator.
Keep freezer full: A full freezer maintains temperature better than an empty one (use water bottles if needed).
Place away from heat: Keep away from ovens, radiators, direct sunlight.

Note: NoFrost technology eliminates manual defrosting, saving energy and maintenance time.
