Refrigerator maintenance tips to improve energy efficiency

To prevent excessive energy consumption and ensure uniform cooling, refrigerator maintenance should focus on proper placement and ventilation. Ensuring there is sufficient space around the appliance and that heat dissipation zones are not obstructed can improve efficiency.

Users should also check that door seals are clean and undamaged, as a poorly sealing door forces the compressor to work harder. It is recommended to avoid overfilling the unit to allow for proper air circulation. For optimal food safety, the US Department of Agriculture suggests maintaining refrigerator temperatures at 4°C or below and freezers at -18°C. If the appliance makes unusual noises or fails to cool consistently, professional service is advised.
