Place the refrigerator on level ground and leave enough space around it for good air circulation, at least 2.5 cm. Also, there should be no obstacles to the right or left when opening the door and avoid placing it near heat sources such as ovens or radiation from direct sunlight.

Do not overload the fridge, leave enough room for air flow, clean the door seals, and make sure the temperature is set correctly (about 4°C in the fridge and -18°C in the freezer).
