Mist-like cold air being visible when the door is open is a phenomenon that occurs when moisture in the outside air meets cold air from inside the refrigerator and the temperature difference causes the moisture to take on the appearance of white mist (water vapor).
In particular, it frequently occurs during the humid rainy season of summer and is not clearly visible in drier weather.
In the refrigerator, the defrosting operation runs the heater to remove any ice that has accumulated in the condenser (evaporator) in order to maintain a continuous low temperature.
At this time, when the refrigerator door is opened during heater operation, white mist (water vapor) may be visible temporarily, but this is quite normal.
