● Noise (resonance) problems
generating BLDC motors for
both of the compartments are
replaced several times. What
does generate the resonance
in low RPM, The friction with air
is quite high and it generates
If you replace the ambient
thermistor with a 2.7K resistance
(detecting 43℃), the BLDC fan
motor rotates in high RPM,
reduces friction with air resulting
in reduction of the ‘grinding”
● What causes the “knocking”
It makes ‘knocking” or “branch
breaking” noises when the liner
and the shelves hit each other
due to the fluctuation of
air pressure upon door open/
close. Also, these noises occur
when the liners and the shelves
hit each other as the liners
expand and contract due to the
temperature change in both of the
Check the clearance between the
① Freezer Shelves: Remove the
trim shelves already attached
and replace them with those
② Fridge Shelves: Because
noisepreventing trim selves are
not attached, it needs attaching.
● What is the solution if the same
problem occurs even though
the counter action in the service
already for the “knocking”
Check if the selves wobble. If
they do, have shelves sit firmly
● What causes the liquid passing
noises from the back of the
Refrigerant goes into the evaporator via the capillary t
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
evaporator with a bigger diameter, which causes the
refrigerant noises. And, it gets worse when the
refrigerant does not flow
● What is the solution for the
Check if the refrigerator is leveled.
Check if the refrigerator wobbles
Check if there is enough clearance
for the ventilation of the machine
or it is blocked by things such
as newspaper, there could be
