Improvements in refrigeration design may produce sounds in your new refrigerator that are different or were notpresent 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 refrigerators run quieter, sounds may be detected thatwere present in older refrigerators, 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 thesesounds seem even louder. The following are some of the normal sounds that may be noticed in a new refrigerator.Clicking • Freezer control (A) clicks when starting or • Normal operationstopping compressor.• Motorized device (B) sounds like an electric • Normal operationclock and snaps in and out.Air rushing or • Freezer fan (C) and condenser fan (D) make • Normal operationwhirring this noise while operating.Gurgling or • Evaporator (E) and heat exchanger (F) • Normal operationboiling sound refrigerant makes this noise when flowing.Thumping • Ice cubes from ice maker (select models) drop • Normal operationinto ice bucket (G).Vibrating noise • Compressor (H) makes a pulsating sound • Normal operationwhile running.• Refrigerator is not level. • See page 3 for details on how to levelyour refrigerator.Buzzing • lee maker water valve (I) hookup (select • Normal operationmodels) buzzes when ice maker fills withwater.Humming • Ice maker (J) is in the 'on' position without • Stop sound by raising ice maker armwater connection, to OFF position see page 12.• Compressor (H) can make a high-pitched hum • Normal operationwhile operating.Hissing or • Defrost heater (K) hisses, sizzles or pops when • Normal operationpopping operational.23
