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.
■ You may hear a whooshing sound when the doors close.
This is due to pressure equalizing within the refrigerator.
■
Electronic models only:
■ 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 the fans spinning. The fans help to
maintain the correct temperatures.
■ Electronic models only:
■ 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.
■ 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.
■ 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.
■ On models with a dispenser, during water dispense,
you may hear the water lines move at initial dispense
and after dispenser button is released.
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 operating sounds, see the
