[LG refrigerator - noise] Strange noises (clattering, humming, buzzing, or crackling sounds) occur during operation.
Do you hear a humming or buzzing sound coming from your refrigerator?
➔ Running a refrigerator requires various moving parts.
These parts may sometimes make various sounds while running.
There is a fan in the refrigerator that circulates cold air to keep it at the set operating temperature.
A humming or buzzing sound may occur while the fan is running normally.
This may be similar to the sound of an electric fan.
Do you hear a clattering or zinging sound?
➔ Sometimes when the fan is interfered with by an object or the motor is frozen by the cold temperature inside the refrigerator, a clattering, zinging, or buzzing sound may be heard.
In this case, the motor or cooler should be de-iced.
This may take about a day in the summer, 3 days in the winter, with the power plug pulled out.
If, however, you are worried about your food, it is recommended that you contact LG Service for an inspection by a service technician.
Do you hear a humming or buzzing sound?
➔ The cooling motor (compressor) generates heat while running.
To disperse the heat, the fan revolves and makes a humming or buzzing sound.
If the sound is irregularly or continuously occurring, is is recommended that you contact LG Service for an inspection by a service technician.
Do you hear a clattering or rattling sound?
➔ If the fan is contacted by loose matter such as dust, a clattering or rattling sound may be heard.
In the mechanical compartment at the back of the refrigerator, there is a fan revolving to ensure normal refrigerator operation.
In this case, you can pull out the power plug and clean the mechanical compartment at the back of the refrigerator.
If, however, it is difficult for you to do it yourself, it is recommended to contact LG Service for an inspection by a service technician.
Do you hear humming, buzzing, or whizzing sounds?
➔ Humming, buzzing, or whizzing noises may occur in the course of the refrigerator producing cold air.
Normal operation of a refrigerator requires cold air that keeps the internal temperature low.
Cold air is made by the cooling motor (compressor) compressing and circulating the refrigerant.
The cooling motor (compressor) runs any time it needs to maintain the temperature inside the refrigerator.
In addition, when the refrigerator is installed anew or when the compressor starts running after defrosting to remove frost from inside the refrigerator, an especially loud noise may occur.
Is a clattering or rattling sound heard?
➔ A clattering or rattling sound may be made by the switching valve when the direction of refrigerant is changing.
The freezing compartment maintains lower temperatures than the refrigeration compartment as it has to store food safely over long periods.
At this time a noise may occur for a moment from the switching valve.
This is a normal sound. Don’t worry and continue to run your machine.
