In summer, higher room temperatures and more frequent door openings make the refrigerator work harder. If you notice the internal temperature rising above 4°C, lower the thermostat slightly so the refrigerator maintains an internal temperature of 3–4°C. The goal is not simply to set the control lower but to keep the actual food temperature safely below 4°C.
Freezer Temperature
The freezer should be kept at −18°C (or slightly colder, up to −20°C) to preserve frozen food safely and maintain its quality over time.
Tips for Better Efficiency
- Avoid opening the refrigerator door more often than necessary.
- Do not overload the refrigerator, as air needs to circulate freely.
- Allow hot food to cool before placing it inside.
- Check the temperature occasionally with a refrigerator thermometer for the most accurate reading.
Keeping your refrigerator at the proper temperature helps preserve food, reduce food waste, and improve energy efficiency throughout the year.
