Descriptions of symptoms
▶What causes the liquid
passing noises from the
back of the refrigerator?
▶What is the solution for the
compressor noises?
Check Points
Refrigerant goes into the evaporator via the capillary tube in which the
refrigerant expands as it circulates the cooling cycle. At this time, the
refrigerant is in its liquid state and it starts evaporating as it reaches at the
inlet of the evaporator with a bigger diameter, which causes the refrigerant
noises. And, it gets worse when the refrigerant does not flow freely.
For new refrigerators
Check if the refrigerator is leveled.
Check if there is enough clearance at
the back of the refrigerator for the
ventilation of the machine
compartment.
Required clearance around the
