Normal Newer appliances sound different from older appliances. Modern appliances have more features
and use newer technology.
operating
sounds
• The new high efficiency compressor may run
faster and longer than your old appliance
and you may hear a high-pitched hum or
pulsating sound while it is operating.
• Sometimes the appliance runs for an
extended period, especially when the
drawers are opened frequently.
• You may hear a whooshing sound when
the drawers close. This is due to pressure
equalizing within the appliance.
• The cabinet fan runs continuously except
when the drawer is opened.
CRACKS and CHIRPS
• You may hear cracking or popping sounds
when the appliance is first plugged in. This
happens as the appliance cools to the
correct temperature.
• Electronic dampers click open and closed to
provide optimal cooling and energy savings.
• The electronic control board may cause
a clicking sound when relays activate to
control appliance components.
• Expansion and contraction of cooling
coils during and after defrost can cause a
cracking or popping sound.

The Problem Solver
Double-Drawer Refrigerator
• You may hear the fans spinning at high
speeds. This happens when the appliance is
first plugged in, when the drawer is opened
frequently or when a large amount of food
is added to the appliance. The fans help
maintain desired temperatures.
• If the drawer 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.
• 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 drawer may cause a gurgling
sound due to pressure equalization.
