Troubleshooting
Normal Operating Sounds
Improvements in refrigeration design may produce sounds in your new refrigerator that are different or were not
present in an older model. These improvements were made to create a refrigerator that is better at preserving food,
is more energy efficient, and is quieter overall. Because new units run quieter, sounds may be detected that were
present in older units, but were masked by higher sound levels. Many of these sounds are normal. Please note that
the surfaces adjacent to a refrigerator, such as hard walls, floors and cabinetry may make these sounds seem even
louder. The following are some of the normal sounds that may be noticed in a new refrigerator.
DEFROST TIMER: Frost-free 
refrigerators have a defrost timer 
that will generate a clicking 
sound when it cycles the unit 
into and out of defrost cycle.
ICE MAKER:  (if equipped) The ice maker 
will occasionally generate a rattling sound 
when the ice cubes are ready to drop down 
into the ice bin.  Also, the motor that ejects 
the ice from its tray prior to dropping the 
ice may also be detectable. These are 
normal sounds necessary for making ice.
FREEZER COMPARTMENT 
CONTRACTION AND EXPAN-
SION:
 A popping sound may 
occur in the freezer when the 
unit starts up due to contraction 
or expansion of the materials in 
the freezer area.
DEFROST HEATER: During 
the automatic defrost cycle, a 
sizzling sound may be heard 
as water droplets come into 
contact with the defrost 
heater.  This is a normal 
sound heard during defrost.
REFRIGERANT FLOW: The flow of the 
refrigerant in your refrigerator may cause a 
gurgling or rattling sound when the unit is 
running or just after the unit cycles off. The 
refrigerant is still flowing in the tubing.
AIRFLOW SOUNDS: Both the freezer 
evaporator fan and the condenser fan at the 
bottom of the cabinet will create airflow 
sounds. The evaporator fan is circulating the 
cold air throughout the refrigerator and freezer 
compartments. The condenser fan is removing 
the heat generated when the unit is cooled.
WATER VALVE (if equipped): A buzzing 
sound may be detected in the back of 
the unit when the ice dispenser calls for 
the water valve to open to fill the ice 
maker tray. Following the ejection of the 
ice, there may be some water dripping 
sounds when the trays are being filled.
CABINET LEVELING: An 
unlevel 
cabinet may cause rattling or vibrating 
noises.  This can be fixed by adjusting 
the wheels or levelers properly.
COMPRESSOR: In order for a new
refrigerator to run more efficiently, 
the refrigeration system may run 
longer to keep food at the desired 
temperatures for freshness. That 
new, high efficiency compressor may 
run longer and generate sounds such 
as a higher pitched hum or pulsation.
