Instructions
You may feel that the operation sound is loud because the compressor 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, or during long vacations or absence.
It is because the compressor operates in low-speed for conserving energy
It is because the system changes the operating power of he refrigerator according to the temperature change.

Possible causes and / or Recommened solutions
Check that the wrapping paper of the food is not getting caught in order not to make gap between door and door gasket when you close the door.

Frost or ice is generated in the freezer compartment

The door of the freezer compartment was not opened frequently or longer time than necessary?

When the door is opened frequently or if the door is opened when the humidity around the refrigerator is high, moisture in the air may be turned into some frost or ice on the inner wall or component of the freezer compartment, or around the air chanels. This is not a failure. Please try not to open the door too many times or for a long time. Also, please wipe frost or ice generated in the freezer compartment off with use of a dry cloth.

Making extra ice by using an additional ice-tray which was not originally installed in the refrigerator?

When the many containers in which water or liquid is stored are put in the same time, water or liquid may be evaporated and turned into frost or ice on the wall or component of the freezer compartment, or around the air channels. You can suppress these frost and ice by putting lid to avoid evaporation Please wipe frost and ice off with use of a dry cloth.

The door of the refrigerator compartment was not left open temporarily?

Please check not to pinch the food or plastic bag between the door and door frame when you close the door.

Dew is generated in the refrigerator compartment
Dew is generated on outer surface of the refrigerator

The door of the refrigerator compartment was not opened frequently or longer time than necessary?

When the door is opened frequently or if the door is opened
when the humidity around the refrigerator is high, moisture in the air may be turned into some dew on the inner wall or component of the refrigerator compartment, or around the chilled air blow-off port. This is not failure . Please try not to open the door too many times or for long time. Also, please wipe off the dew in the refrigerator compartment with adry cloth.

Dew condensation

Storing many vegetables containing much water?

The humidity of the vegetable compartment is higher than other compartments. Accordingly, depending on the amount or type of the vegetable, dew condensation may be generated on the plastic case of vegetable compartment. However, this is not a failure. When you do not want to have this kind of dew, please warp your vegetables in a plastic flim. Also,when the dew condensation happens many times, water may be accumulated in the vegetable compartment. Please wipe the water off with a dry cloth.

The volume of humidity around When the humidity rises such as in rainy day, some dew many be generated on

the outer surface of the refrigerator. Please wipe the dew off with a dry cloth.

The temperature setting is not set as “Coldest”?

When the temperature setting is set as “Coldest”, some dew may be generated on the outer surface of the refrigerator. Please set the
setting as “Normal”. Also, please wipe dew off with use of a dry cloth.

Why frost and dew are generated?

When warm and humid air contacts something cold, dew is generated. For example, if you put some ice in the glass in your room, air around the glass will be cold down and some dew may be generated on the outer surface of the glass.
In the same way, when warm and humid air enters into the refrigerator at the door opening, the warm and humid air contacts cold inner wall and little dew may be generated.
Accordingly, if the door opening is too frequent or too long, dew will be accumulated at every door opening. In some cases, dew may be frozen to generate some frost or ice flakes in the freezer compartment.
