Normal operating sounds.
Newer refrigerators sound different from older refrigerators. Modern refrigerators
have more features and use newer technology.
Do you hear what I hear? These sounds are normal.
HUMMM...
WHOOSH...
s
The new high efficiency compressor may run faster
and longer than your old refrigerator and you may
hear a high-pitched hum or pulsating sound while
it is operating.
s
You may hear a whooshing sound when the doors close.
This is due to pressure equalizing within the refrigerator.
CLICKS, POPS,
CRACKS and CHIRPS
s
You may hear cracking or popping sounds when the
refrigerator is first plugged in. This happens as the
refrigerator cools to the correct temperature.
s
The compressor may cause a clicking or chirping
sound when attempting to restart (this could take
up to 5 minutes).
s
Expansion and contraction of cooling coils during
and after defrost can cause a cracking or popping
sound.
s
On models with an icemaker, after an icemaking
cycle, you may hear the ice cubes dropping into
the ice bucket.
s
On models with a dispenser, during water dispense,
you may hear the water lines move at initial dispense
and after dispenser button is released.
24
s
You may hear the fans spinning at high speeds.
This happens when the refrigerator is first plugged
in, when the doors are opened frequently or when
a large amount of food is added to the refrigerator
or freezer compartments. The fans are helping to
maintain the correct temperatures.
WATER SOUNDS
s
The flow of refrigerant through the freezer cooling
coils may make a gurgling noise like boiling water.
s
Water dropping on the defrost heater can cause a
sizzling, popping or buzzing sound during the
defrost cycle.
s
A water dripping noise may occur during the defrost
cycle as ice melts from the evaporator and flows into
the drain pan.
s
Closing the door may cause a gurgling sound due to
pressure equalization.

icemaker operating sounds, see the
About the automatic icemaker section.
