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...
• 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.
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.
• After an icemaking cycle, you may hear
the ice cubes dropping into the ice bucket.
The Problem Solver
Stainless Steel 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.
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.

icemaker and dispenser operating
sounds, see the Automatic Icemaker
and Internal Water Dispenser
sections.
