✅ What is this “button”
-
On many refrigerators, there is an Energy Saver / Power‑Saver switch (or knob/slider) that controls cooling intensity — often inside the fridge or freezer compartment. research.encompass.com+2ApplianceTeacher+2
-
Some models also include “mullion heaters” or “anti‑condensation heaters” that prevent moisture build‑up on the door — these heaters draw extra power. When you activate the Energy Saver mode, these heaters are turned off, reducing electricity consumption. ApplianceTeacher+1
🔧 How adjusting the setting saves electricity
-
Cooling a refrigerator to colder-than‑necessary temperatures makes the compressor run more, drawing more electricity. In colder seasons (or cooler climates), you don’t always need maximum cooling; reducing the cooling level lets the fridge work less. City Magazine+2Yohanpost+2
-
Experts recommend — when ambient temperatures are lower or the fridge is not overly full — setting the cooling level lower (e.g. “2–3” on a 1–5 scale, or even “1” in winter) to keep food fresh while minimizing energy use. Yohanpost+2thebustednews.com+2
-
If your fridge/freezer is mostly empty (or only lightly loaded), lowering the cooling level makes sense; when heavily loaded (e.g. lots of fresh/frozen food), stronger cooling may be needed. vietbao.vn+2repairexpertindia.in+2
📋 Other complementary habits to save more electricity
Using that little button helps — but even with correct settings, fridge power use depends also on other usage habits. For bigger savings, also:
-
Clean the condenser coils / ensure back/side ventilation — dust and blocked airflow make the fridge work harder. sarroselectrical.com.au+2Show Me the Green+2
-
Check the door seals/gaskets to prevent cold air leaks; if seals are weak or leaky, fridge uses more energy. smarterhouse.org+2NREL+2
-
Avoid putting hot food directly into the fridge/freezer — let it cool a bit first so the compressor doesn’t overwork. smarterhouse.org+2e-malabari.my+2
-
Try not to open the fridge door unnecessarily or keep it open for long; each opening lets cold air escape, forcing the fridge to consume more electricity. TipsMake+2smarterhouse.org+2
⚠️ What to watch out for
-
On some units, turning on “Energy Saver” / switching off mullion heaters might cause condensation or moisture on the door frame — if you see water drips, consider turning it off (especially in humid seasons). research.encompass.com+2ApplianceTeacher+2
-
In hot weather or when fridge is often opened/closed, too low cooling settings may not preserve freshness properly — especially for perishables (meat, dairy, etc.). Adjust settings appropriately depending on load and season.
