Operation sound lasts long.

●
-
Annoying sound is generated
by the refrigerator.
●
You may feel that the operation sound is loud because the
compressor operates in high-speed under the
following conditions: the refrigerator does not cool fully
on the occasion such as using it for the first time,
opening/closing the door frequently, the surrounding
temperature is high.
The sound becomes more quiet after cooling fully.
The compressor operates at low speed at night, or during
long vacations or absence.
It is because the compressor operates in low-speed for
conserving energy
It is because the system changes the operating power of
he refrigerator according to the temperature change.
Operation sound sometimes
becomes louder.
