HUMMM...
WHOOSH...
■ T he 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.
■ Y ou may hear a whooshing sound when the doors
close. This is due to pressure equalizing within the
refrigerator.
CLICKS, POPS,
CRACKS and SNAPS
■ 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.
■ 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.
■ I f 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.
WATER SOUNDS
■ The flow of refrigerant through the 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.
■ C losing the door may cause a gurgling sound due to
pressure equalization.

icemaker and dispenser operating sounds,
