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 refrigerators run quieter, sounds may be detected that were 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 these sounds seem even louder. The following are some of the normal sounds that may be noticed in a new refrigerator. SOUND Clicking Air rushing or whirring Gurgling or boiling sound Thumping Vibrating noise Buzzing Humming Beeping POSSIBLE CAUSES • Freezer control (A) clicks when starting or stopping compressor. • Defrost timer or electric damper control (select models) (B) sounds like an electric clock and snaps in and out of defrost cycle. • Condenser fan (D) makes this noise while operating. • Freezer fan (C) makes this noise while operating. • Freezer fan (C) slows to a stop as the freezer door is opened. • Evaporator (E) and heat exchanger (F) refrigerant make this noise when flowing. • Ice cubes from ice maker drop into ice bucket (G). • Dispenser ice chute (H) closing. • Compressor (I) makes a pulsating sound while running. • Refrigerator is not level. • Ice maker water valve (J) hookup buzzes when ice maker fills with water. • Ice maker (K) is in the 'on' position without water connection. • Ice auger (L) hums as auger agitates ice during dispensing. • Compressor (I) can make a high pitched hum while operating. • Solenoid valve (M) operating ice chute door. • Doors are open, or have not been properly closed. • Door Alarm, Temp Alarm.
