When refrigerator is first used or at starting,
it can produce stronger drones because its
running is not steady, and the sound shall
become smaller, as running stabilizes.
Sometimes, the outside of the appliance
gets hot, especially for the first use after
switching it on. But this is not a defect, it is
just designed for preventing dew, rust, and
for energy saving. It is normal.
When liquid refrigerant flows in evaporator,
it can produce the sound similar to water
flowing. This kind of sound usually occurs
at the evaporator and compressor parts:
when refrigerator stops working, the liquid
refrigerant flow back, it shall also produce
the continuous or interrupted "gurgling
water flowing" sound.
When refrigerator is used for the first time, or
when in starting, it can give out bigger sound
because the appliance is not in steady running
state. The sound shall become diminished as
its running becomes steady.
The sound produced at compressor working,
and the tap-tap sound when compressor
starts or closes: all these are normal.
When carrying out the defrosting cycle, the
water fallen down on heating element can
give out the sound of "hiss" or "tittering". At
the end of defrosting, it is possible to produce
slight "crackling". At the same time,
evaporator can produce the sound of
"boiling" or "gurgling". This is normal state
caused by defrosting.
