Normal Operating Sounds & Sights 33 UNDERSTANDING THE SOUNDS YOU MAY HEAR Your new high-efficiency refrigerator may introduce unfamiliar sounds. These sounds normally indicate your refrigerator is operating correctly. Some surfaces on floors, walls, and kitchen cabinets may make these sounds more noticeable. NOTE Energy efficient foam in your refrigerator is not a sound insulator. Following is a list of major components in your refrigerator and the sounds they can cause: A Evaporator Refrigerant through the evaporator may create a boiling or gurgling sound. B Evaporator Fan You may hear air being forced through the refrigerator by the evaporator fan. C Defrost Heater During defrost cycles, water dripping onto the defrost heater may cause a hissing or sizzling sound. After defrosting, a popping sound may occur. IMPORTANT During automatic defrost cycle, a red glow in the back wall vents of your freezer compartment is normal. D Automatic Ice Maker When ice has been produced, you will hear ice cubes falling into the ice bin. E Cold Control & Automatic Defrost Control These parts can produce a snapping or clicking sound when turning the cooling system on and off. F Condenser Fan You may hear air being forced through the condenser. G Compressor Modern, high-efficiency compressors run much faster than in the past. The compressor may have a high-pitched hum or pulsating sound. H Water Valve Makes a buzzing sound each time it opens to fill the ice maker. I Drain Pan (not removable) You may hear water dripping into the drain pan during the defrost cycle. J Condenser May create minimal sounds from forced air. K Motorized Damper May produce a light humming during operation.
