The back and side plates may be heated especially when starting up or if the door is frequently opened and closed.
● The two compartments are connected with an air duct. When closing one of the doors, the door may be opened by
the air pressure through the duct.This is a normal phenomenon.
● The sound like water flowing and boiling water is the sound of the cooling liquid (refrigerant).
● A creaking sound comes from the storage compartment. It is the sound caused by friction of the parts due to temperature change.
● You may feel that the operation sound is larger because the comppressor operates in high-speed under the following conditions:
The refrigerator does not cool fully on the occasion such as using it for the first time, opening/closing the door frequently, the surrounding
temperature is high.
The sound becomes more quiet after cooling fully.
The compressor operates at low speed at night, for long vacations or absences, potentially creating large vibrations.
● It is because the compressor operates in low-speed for conserving energy
● It is because the system changes the operating power of the refrigerator according to the temperature change.
