Ice up in the freezing
chamber
Abnormal noise
There is a peculiar
smell in the units
the forefront or the
middle cabinet heats
Refrigerator's two
sides or the back
heat
the cabinet surface
condensation
◆ The solution for the common problem.
1.Cooling is not enough good
(Many reasons might cause that cooling not enough good, as blow :)
Reason
1) Leakage of Gas
2) The quantity of
Gas is too much
3.9 Does the gas leak?
4.1 Is the setting of the temperature appropriate?
4.2 Is there multi-moisture food and too close to the back wall of the refrigerator?
4.3 Is the ambient temperature too low?
4.4 Is the electric parts on good condition, specially the thermostat wich will
cause the unit non-stopping
5.1 Is the refrigerator stably placed?
5.2 Does the refrigerator bump other objects?
5.3 Whether the internal accessory of the refrigerator is in the right place.
5.4 Whether the water plate of compressor is fall from the unit.
5.5 Does the tube of the refrigeration system bump each other?
5.6 The noise sound likes Water flow inside the refrigerator, in fact,it is normal,
which is caused both when refrigerator start and shut-down; in addition,
frost-dissolving causes this sound, too, which is a normal phenomenon.
5.7 There will be a cracking sound in the cabinet ,when the cabinet or cabinet
accessory contracting or expanding, this sound will be made, which is normal.
5.8 The motor operation sound in the compressor is appears to be louder at night
or begin starting. which is a normal phenomenon; also the uneven placing would
lead to too much running noise.
6.1 Is the food with special smell sealed tight?
6.2 Does it have long time storing food or degenerated food?
6.3 Whether the internal cabinet needs cleaning.
7.1 As fridge Anti-condensation tube is placed here and caused the above
phenomenon, which is normal.
8.1 As condensation tube is placed here and caused the above phenomenon,
which is normal.
9.1 Air humidity is too large.
analysis
If some gas leaked unit will work not well.
Phenomenon of failure:
a. lower pressure of liquid cycle system
b. high temperature of copper tube of
discharging gas, hand feels very hot.
C. much noise, sounds like "ZZZZZ", comes
from outlet of capillary.
d. the temperature fell down very slowly.
If too much Gas was charged into the cycle
system, the extra gas will occupy some
space of evaporator, so that the area of heat
exchange becomes less, unit will work not
Solutions
First find out the point of leaking
on tube, and then sealed it,
vacuuming it, finally recharge with
Gas.
Note:
If you find oil on somewhere, it is
possible that leakage point is
there.
First stop unit for several minutes,
and then open charging tube,
discharge all of gas. Change a
new filter, and then recharge gas,
