NORMAL OPERATING CONDITIONS
Newer refrigerators sound different from older refrigerators. Modern refrigerators have more features and use newer
technology.
• 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.
• You may hear a whooshing sound when the doors close.
This is due to pressure equalizing within the 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.
• The fans change speeds in order to provide optimal cooling
and energy savings.
• You may hear cracking or popping sounds when the
refrigerator is first plugged in. This happens as the
refrigerator cools to the correct temperature.
• Expansion and contraction of cooling coils during and after
defrost can cause a cracking or popping sound.
• On models with an icemaker, after an ice making cycle, you
may hear the ice cubes dropping into the ice bucket.
• On models with a dispenser, during water dispense, you
may hear the water lines move at initial dispense and after
dispenser button is released.
• 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.
• Closing the door may cause a gurgling sound due to
pressure equalization.
