Does refrigerator produce clanking noise?
When a refrigerator is not properly levelled with a slight inclination towards the back to facilitate
door easily closing, pipes at the back can rub against other metal parts generating clanking noises
from the vibration.
Slightly elevate the front of the refrigerator when leveling the refrigerator.
※ If the refrigerator makes a loud metallic noise, contact LG customer service.
