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 sounds while
it is operating.
• Sometimes the appliance runs for an
extended period, especially when the doors
are opened frequently.
• You may hear a whooshing sound when
the doors close. This is due to pressure
equalizing within the appliance.
• The cabinet fan runs continuously except
when the door 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.
• 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 cracking
or popping sounds.

Fresh-Food Refrigerator
• You may hear the fans spinning at
high speeds. This happens when the
appliance is first plugged in, when the door
is opened frequently or when a large amount
of food is added to the appliance. The fans
help maintain desired temperatures.
• If the 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.
