DIAGNOSIS Yes, this is normal for the first 24 hours. The sound is refrigerant and oil settling in the lines after shipping. The unit was likely on its side or back during transport.
FIX Let the refrigerator run, undisturbed and level, for a full day. Do not adjust the thermostat constantly. The noises should gradually subside as the system stabilizes. Ensure there's at least 2 inches of clearance on all sides for proper airflow.
IF THAT DIDN'T WORK If loud gurgling or hissing persists beyond 48 hours, or is accompanied by poor cooling, you may have a restricted capillary tube or a refrigerant leak. This requires a professional technician.
HEADS UP You must let the refrigerator stand upright for at least 4 hours before plugging it in after moving it. This lets the compressor oil drain back to where it belongs.
