chamber
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 .
Abnormal noise
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.
There is a peculiar
smell in the units
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.
the forefront or the
middle cabinet heats
7.1 As fridge Anti-condensation tube is placed here and caused the above
phenomenon, which is normal.
Refrigerator’s two
sides or the back

8.1 As condensation tube is placed here and caused the above
phenomenon, which is normal.

9.1 Air humidity is too large.

Solutions
1) Leakage of Gas
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.
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.
2) The quantity of
Gas is too much
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 well.
Phenomenon of failure:
a, higher pressure of liquid cycle system
First
stop
unit
for
several
minutes,
and
then
open
charging tube, discharge all of
gas. Change a new filter, and
then
recharge
gas,
finally
sealed the system.
