HUMMM...WHOOSH... The new high efficiency compressor may run fasterand longer than your old refrigerator and you mayhear a high-pitched hum or pulsating sound whileit is operating. You may hear a whooshing sound when the doors close.This is due to pressure equalizing within the refrigerator.Consumer SupportTroubleshooting TipsOperating InstructionsSafety Instructions Installation Instructions25Normal operating sounds. www.GEAppliances.comNewer refrigerators sound different from older refrigerators. Modern refrigeratorshave more features and use newer technology. You may hear the fans spinning at high speeds.This happens when the refrigerator is first pluggedin, when the doors are opened frequently or whena large amount of food is added to the refrigeratoror freezer compartments. The fans are helping tomaintain the correct temperatures.CLICKS, POPS,CRACKS and CHIRPS You may hear cracking or popping sounds when therefrigerator is first plugged in. This happens as therefrigerator cools to the correct temperature. The compressor may cause a clicking or chirpingsound when attempting to restart (this could takeup to 5 minutes). Expansion and contraction of cooling coils duringand after defrost can cause a cracking or poppingsound. On models with an icemaker, after an icemakingcycle, you may hear the ice cubes dropping intothe ice bucket.WATER SOUNDS The flow of refrigerant through the freezer coolingcoils may make a gurgling noise like boiling water. Water dropping on the defrost heater can cause asizzling, popping or buzzing sound during thedefrost cycle. A water dripping noise may occur during the defrostcycle as ice melts from the evaporator and flows intothe drain pan. Closing the door may cause a gurgling sound due topressure equalization.Do you hear what I hear? These sounds are normal.For additional information on normalicemaker operating sounds, see theAbout the automatic icemaker section.
