Refrigerator: Sounds and Operational Noises

•   The plastic parts of the refrigerator contract and expand as the temperature of the refrigerator rises and falls, causing cracking noises. 

•   This usually happens during the defrosting cycle. This cannot be eliminated with service. It is a characteristic of all refrigerators, not just Samsung refrigerators.

•   This is the sound of water filling the ice maker, or the sound of the compressor. The compressor will automatically turn on and off. It will run at varying speeds as needed, but is generally very quiet.

Note: To avoid damage, turn off the ice maker if a water line is not connected.

•   An alarm will sound when the door is not closed. If the doors are closed and the display is blinking, look for an error code.

•   This sound comes from the refrigerator's circulation fans. It's rare, but normal.

•   Water dripping onto the defrost heater makes a hissing or sizzling sound.

•   Refrigerant moving through the changes from liquid to gas and back again. This makes the bubbling sound.
