Refrigerators are an essential part of every modern home, working 24/7 to keep our food fresh and safe. However, they’re also among the most energy-consuming appliances in the household, especially when running non-stop throughout the year. But did you know there’s a small adjustment you can make on your refrigerator in the winter that can significantly cut down your electricity bills?

Many people overlook this simple trick, but it’s incredibly effective. Let’s uncover the secret to optimizing your refrigerator’s energy consumption and explore a few other tips to maximize savings.

How Refrigerator Temperature Affects Energy Use

According to data from Vietnam Electricity Corporation (EVN), a standard refrigerator consumes between 50–75 kWh per month, making it one of the top three energy guzzlers in a home, right after electric stoves and water heaters.

While refrigerators are built to maintain a constant temperature year-round, the external climate significantly affects their efficiency. In summer, refrigerators work harder to maintain low temperatures, but in winter, they don’t need to exert as much effort.

This is where the refrigerator’s temperature control button comes into play.

Adjusting Your Refrigerator Temperature in Winter

Modern refrigerators usually have temperature settings ranging from 1 to 5 or 1 to 6. During hot summer months, most people set their fridge to the highest cooling level. However, in winter, you can safely lower this setting without compromising the freshness of your food.

Recommended Winter Settings:

• Fridge Compartment: Level 1 or 2 (2–5°C / 35–41°F)
• Freezer Compartment: Maintain at approximately -18°C (0°F) for frozen foods and seafood.

This adjustment ensures your refrigerator operates efficiently without overworking the compressor, leading to noticeable savings on your electricity bill.

Additionally, the cooling level can also depend on the amount of food in the refrigerator:

• Light Load: Lower cooling levels are sufficient.
• Heavy Load: Higher cooling levels are required to maintain consistent temperatures.

Additional Tips to Save Electricity with Your Refrigerator

Adjusting the temperature setting is a great start, but there are a few more habits you can adopt to make your refrigerator even more energy-efficient.

1. Choose the Right Location

The placement of your refrigerator plays a significant role in its energy efficiency.

• Keep it away from heat sources like ovens, stoves, or microwaves.
• Ensure there’s at least 4 inches of space between the refrigerator and the wall to allow proper air circulation.
• Avoid placing the refrigerator in direct sunlight.

These steps ensure that your refrigerator doesn’t have to work harder to release heat, prolonging its lifespan and saving energy.

2. Avoid Overloading the Refrigerator

While it’s tempting to stock up the fridge, overcrowding blocks airflow and forces the appliance to work harder. Keep your refrigerator moderately stocked to allow even cooling throughout the compartments.

3. Don’t Keep the Door Open Too Long

Every time you open the refrigerator door, cold air escapes, and the compressor works harder to restore the temperature. Try to:

• Minimize how long the door stays open.
• Plan ahead to grab everything you need in one go.

4. Check the Door Seals Regularly

Worn-out or loose seals can cause cold air to leak out, making the refrigerator work overtime. Ensure the door seals are tight and replace them if you notice any damage.

5. Regular Maintenance and Defrosting

• Clean the coils at the back of the refrigerator every six months to ensure efficient heat dissipation.
• If your fridge isn’t frost-free, defrost it regularly to prevent ice buildup, which can reduce efficiency.

Why These Changes Matter

These small adjustments might seem insignificant, but they can lead to substantial savings over time. Lowering the cooling level in winter and adopting smart usage habits not only reduces your electricity bills but also prolongs your refrigerator’s lifespan.

By paying attention to these details, you can reduce energy waste, protect your appliance, and contribute to a more sustainable lifestyle—all while keeping your food fresh and safe.

Final Thoughts

Refrigerators are a cornerstone of modern households, but they don’t have to be a burden on your electricity bill. With a simple adjustment of the temperature settings and mindful usage habits, you can enjoy fresh food and lower energy costs throughout the year.
