Applies to

  • Refrigerators
  • Fridge freezers
  • Freezers


You should keep your fridge temperature set at 4°C and your freezer set at -18°C. It can make your food last longer and help reduce waste, which is more sustainable.

You can check the temperature of your fridge by placing a thermometer in a glass of water that has been in the fridge for a few hours.

Increase slightly the set temperature in the summer season.

The optimal ambient temperature of the appliances should be 20-25°C.

The highest number on a rotary dial will be the coldest temperature in the fridge, 0 will turn off the fridge and 6 will be the coldest.
