4. The hidden “defrost” button prevents ice buildup
Some older or simpler fridge models have a small button that triggers manual defrost mode.
Ice buildup in the freezer or cooling vents forces the motor to work harder, increasing energy consumption by as much as 30%.
Pressing the defrost button:
• melts accumulated frost
• restores proper airflow
• reduces strain on the compressor
• improves cooling efficiency
Regular defrosting keeps electricity usage stable and prevents expensive repairs later.
5. Small adjustments in placement also prevent wasted electricity
Using the temperature button properly is important — but the fridge’s efficiency also depends on how it’s used daily.
Simple habits can make a big difference:
• Keep the fridge 5–10 cm away from the wall
• Avoid overpacking the shelves
• Let hot food cool before placing it inside
• Check door seals for leaks
• Clean the back coils at least twice a year
These small steps reduce the workload on the compressor and help the temperature control button do its job.
6. Most people set the fridge too cold without realizing it
Studies show that many households unknowingly run their refrigerators colder than necessary.
A fridge that is even 2–3°C colder than required uses much more electricity — sometimes equivalent to leaving a lamp on all day.
Because the temperature dial is not intuitive, people often turn it toward the extreme without connecting it to their rising power bill.
Learning how this single button works can improve efficiency immediately.
