- Setting the temperature to level 2 or 3, or even level 1 in winter, is completely reasonable.
- At level 1, the refrigerator’s temperature usually ranges between 2–5°C, which is still sufficient to keep food fresh while consuming less electricity.
- This same adjustment can be applied to the freezer compartment, lowering energy usage while maintaining food safety.
By making this small adjustment, households can significantly reduce electricity bills without compromising food storage.
Adjusting the Temperature Based on Food Storage Needs
Aside from seasonal changes, the refrigerator’s cooling level should also be adjusted based on the amount of food stored.
- If the refrigerator is not full, reduce the cooling level to avoid unnecessary power consumption.
- If storing large amounts of food, increasing the cooling level ensures proper preservation.
- For freezer compartments, if storing a lot of fresh food such as seafood, it is best to maintain a high cooling level at around -18°C. This temperature prevents bacterial growth and keeps food fresh for a longer period.
