Most of the time, this is normal noise.
Before calling technical service for assistance, please
read these few lines.
These sounds are completely normal: buzzing, roaring,
clicking,
cracking
...
When the cellar has just stopped working, you may
hear a buzzing, roaring, clicking or squealing noise.
When the operation stabilizes, the sounds subside.
For direct cooling, some kind of irregular cracking,
hissing, bubbling, crackling can often be heard when
the compressor is running for a while or has just
stopped. This sound is caused by the relief of stress
due to expansion and contraction when temperature
changes, and will not be affected by normal
application of the product.
The compressor consists of an electric motor and a
compression device. Due to the heat produced
during the compression of the refrigerant, it is
possible especially in summer when the ambient
temperature is higher that heat is emitted by the cellar.
All of these phenomena are normal.
To reduce some noises:
First, make sure your cellar is on a level surface.
Location is important, do not lean the cellar against
the wall.
