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.

	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

	sound heard during defrost.
	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.
	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
