TROUBLESHOOTING TIPS: Normal Operating Conditions
Newer refrigerators sound different from older refrigerators.
Modern refrigerators have more features and use newer technology.
HUMMM...
WHOOSH...
Ŷ 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.

close. This is due to pressure equalizing within the
refrigerator.
Ŷ
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.
Ŷ
The fans change speeds in order to provide optimal
cooling and energy savings.
CLICKS, POPS,
CRACKS and SNAPS
Ŷ You may hear cracking or popping sounds when
the refrigerator is first plugged in. This happens as
the refrigerator cools to the correct temperature.
Ŷ Expansion and contraction of cooling coils during
and after defrost can cause a cracking or popping
sound.
Ŷ On models with an icemaker, after an ice making
cycle, you may hear the ice cubes dropping into the
ice bucket.
Ŷ 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
Ŷ The flow of refrigerant through the cooling coils may
make a gurgling noise like boiling water.
Ŷ Water dropping on the defrost heater can cause
a sizzling, popping or buzzing sound during the
defrost cycle.
Ŷ A water dripping noise may occur during the defrost
cycle as ice melts from the evaporator and flows
into the drain pan.
Ŷ Closing the door may cause a gurgling sound due to
pressure equalization.
Do you hear what I hear? These conditions are normal.
