Q & A
The following phenomena are not faults:
In case of first use or startup, the freezer may work for a long time or give out loud noise, etc. That is
not a fault but normal phenomenon.
It is normal that the condenser fan starts and stops automatically according to ambient temperature.
It is normal that there is fluid flow noise from the freezer arising from the cycle flow of refrigerant in
its pipeline.
