Normal operating sounds.
Newer refrigerators sound different from older refrigerators.
Modern refrigerators have more features and use newer
technology.
HUMMM...
WHOOSH...
■
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.
■
Sometimes the refrigerator runs for an extended period,
especially when the doors are opened frequently. This
means that the Frost Guard
™
feature is working to
prevent freezer burn and improve food preservation.
■
You may hear a whooshing sound when the doors close.
This is due to pressure equalizing within the refrigerator.
■
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.
■
If either door is open for over 3 minutes, you may
hear the fans come on in order to cool the light
bulbs.
■
The fans change speeds in order to provide optimal
cooling and energy savings.
CLICKS, POPS,
CRACKS and CHIRPS
■
You may hear cracking or popping sounds when the
refrigerator is first plugged in. This happens as the
refrigerator cools to the correct temperature.
■
Electronic dampers click open and closed to provide
optimal cooling and energy savings.
■
The compressor may cause a clicking or chirping
sound when attempting to restart (this could take
up to 5 minutes).
■
The electronic control board may cause a clicking
sound when relays activate to control refrigerator
components.
■
Expansion and contraction of cooling coils during
and after defrost can cause a cracking or popping
sound.
■
On models with an icemaker, after an icemaking
cycle, you may hear the ice cubes dropping into
the ice bucket.
WATER SOUNDS
■
The flow of refrigerant through the freezer cooling
coils may make a gurgling noise like boiling water.
■
Water dropping on the defrost heater can cause a
sizzling, popping or buzzing sound during the
defrost cycle.
■
A water dripping noise may occur during the defrost
cycle as ice melts from the evaporator and flows into
the drain pan.
■
Closing the door may cause a gurgling sound due to
pressure equalization.
Do you hear what I hear? These sounds are normal.

icemaker and dispenser operating sounds,

and About the ice and water dispenser
sections.
