Why does my LG fridge freezer make so much noise at certain times?
If the internal temperature is not sufficiently cool within your fridge freezer then the
motor and fan motor will be forced to run at a high speed to bring that temperature down
to the correct level. This unfortunately can produce a loud noise during this cool
down period. Of course the noise level may differ for each case depending on house
structure, refrigerator location, floor materials and product level.
You will find that your products motor will run at different speeds depending on inside
temperature which can result in inconsistent noise levels.
However it is a normal phenomenon, and not a defect of your fridge freezer.
