HUMMM...WHOOSH... The new high efficiency compressor may run faster andlonger than your old refrigerator and you may hear ahigh-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.Newer 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 plugged in,when the doors are opened frequently or when a largeamount of food is added to the refrigerator or freezercompartments. The fans are helping to maintainthe correct temperatures.CLICKS, POPS,CRACKS and CHIRPS You may hear cracking or popping sounds whenthe refrigerator is first plugged in. This happensas the refrigerator cools to the correct temperature. The compressor may cause a clicking or chirping soundwhen attempting to restart (this could takeup to 5 minutes). Expansion and contraction of cooling coils during andafter defrost can cause a cracking or popping sound. On models with an ice maker, after an ice makingcycle, you may hear the ice cubes dropping into the icebucket.WATER SOUNDS The flow of refrigerant through the freezer cooling coilsmay make a gurgling noise like boiling water. Water dropping on the defrost heater can cause asizzling, popping or buzzing sound during the defrostcycle. 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 dueto pressure equalization.Do you hear what I hear? These sounds are normal.Normal operating sounds.12
