2. The “sweet spot” setting saves electricity without risking food safety
Experts typically recommend setting the fridge to 3 or 4.
This range keeps food at a safe temperature — between 1°C and 4°C (34°F to 39°F) — while reducing unnecessary compressor activity.
Setting it too low (1–2) may keep the fridge too warm.
Setting it too high (6–7) overcools everything and forces the motor to consume far more energy than needed.
Even a single level adjustment can save 5–15% in electricity usage depending on the model.
3. Some fridges include a special “energy saver” button
Many modern refrigerators have a small button labeled:
• Energy Saver
• Eco Mode
• Power Save
This button disables the internal door heater — a small heating element used to prevent condensation around the door seals.
When humidity is low (which is most of the year in many regions), this heater is unnecessary.
Activating the energy saver mode can reduce power consumption significantly — often without any noticeable difference in everyday use.
It’s one of the simplest ways to save electricity.
