Most people don’t realize their refrigerator has a small setting that can help cut electricity costs during the winter months. While fridges run nonstop all year, they’re also one of the biggest power users in the home, often consuming 50–75 kWh per month. Because winter temperatures are naturally cooler, your refrigerator doesn’t need to work as hard — and a simple adjustment to the temperature knob can make a noticeable difference. Modern fridges usually have cooling levels from 1–5 or 1–6, and while you may use higher settings in hot weather, winter allows you to lower the cooling level safely.

Experts recommend setting the fridge to level 1–3 in winter, depending on the model and the amount of food stored. At level 1, temperatures usually fall between 2–5°C, which is enough to keep food fresh while reducing the strain on the compressor. The same principle applies to the freezer: adjust based on how full it is. If it’s lightly stocked, lowering the cooling level saves energy; if it’s full of seafood or raw meat, keep it at a colder setting, ideally around –18°C to prevent bacterial growth and preserve food quality.

Beyond temperature adjustments, several habits can improve refrigerator efficiency. Placing the fridge in a well-ventilated spot helps it release heat more easily, reducing energy use. Avoid keeping it too close to walls or heat-producing appliances like microwaves, ovens, or stoves, as trapped heat forces the compressor to run more often. Proper placement not only saves power but also extends the life of the appliance.

Another essential energy-saving habit is minimizing how long the fridge door stays open. Each time the door remains open, cold air escapes, and the compressor must work harder to restore the temperature. By adjusting settings seasonally and adopting smart usage habits, families can significantly reduce their electricity bills without sacrificing food safety.
