stange voice in refrigerator
）
29
When running the refrigerator at first time, there will
be a loud voice keeping for a short while, as it has
not entered into a steady running status; the voice
will come to be normal after it becomes steady.
There will be a normal voice comes from working
fan while the refrigerator is working.
As the temperature changing occurs when the
refrigerator’s running, things in refrigerator will
expand or contract frequently, so there will be a
pit-a-pat from evaporator and pipelines.
Tap-tap is a normal sound when the compressor
is working, or when you are starting up or shutting
down the refrigerator.
When liquid refrigerant is flowing in the evaporator, it
will produce a voice that sounds like water flow.
Normally, this voice is heard in evaporator and
compressor; when the refrigerator stops working,
such voice may also continuously or discontinuously
occur due to the backflow of liquid working
substance.
When working the defrosting cycle, water drops
onto the hot filament will lead a sound like
“Chi-Chi”. After the cycle gets completed, there
may occurs small cracking sounds, and a boiling
sound or “Gu-Gu” sound may be heard from
evaporator. These are the normal sounds during
defrosting operation.
