TROUBLESHOOTING
◆ The solution for digital display code problem:
There are total 2sensors，one isnear Evaporator which can be only seen when open wind
channel plate in freezer chamber,this is evaporatortemperature sensor. The other is in Freezer
Chamber room， touching the temperature, which is temperature control capillary tube(the
temperature sensor inside the cabinet).
Considering the Sensor connecting or cutting problem, in order to check the problem easier, we
get thedisplay errorto distinguish the problem when we design the product.
When the digital display window shows ‘E1’that means the circuit of the temperature sensor
inside thecabinet is open circuit or short circuit,
When the digital display window shows ‘E2’ that means the circuit of the defrost
sensor(evaporator temperature sensor) is open circuit or short circuit.
The digital display window shows ‘E3’ that means the temperature sensor inside the cabinet and
the defrost sensor occur both fault.

Both sensors are connected on the main board which realize the connection. So when display
shows Erro problem, we need tocheck the sensor itself haveproblem or not，meanwhile, need to
check theconnect well or not between the sensors andmain board.
Detail method showbelow:
The testing method of sensor：
Using the multimeter with the ohm switch to measure the resistor of sensor, normally at
surrounding 25℃ the resistor should be about 2kohm and every with the temperature decreases
1℃ the corresponding resistor value would increase about 45ohm.If the measured value is not
within the normal scope, thesensor isbad and needs to repair or change.
The solution for “E1”problem
Open thedoor andput out the drawer
The location of the sensor inside the cabinet, Open
the sensor cover with screwdriver.
Put off thesensor cover

Using the multimeter with the ohm switch to measure
the resistor of sensor, if sensor is bad ,change a new
one.
Or else ,go on next step.
Measure the resistor of plug, If the resistance figure
shows infinity, that means connection between the
main board and plug have problem.
Unscrew the top Cover’s screws
Remove the top cover

Remove the electron box cover
Checking the connection of main board have
problem or not.
The solution for “E2”problem:
Open thedoor andput outall the drawers
Remove the wind channel plate in freezer chamber.
Put off the foam

The location of the evaporator temperature sensor
always fixed on the suction tube as attached
(sometimes it fixed on the right middle of the
evaporator).
Take off the evaporator temperature sensor ,and
Measure the resistor , if sensor is bad ,change a new
one.
Meanwhile, measure the resistor of wire plug, If the
resistance figure shows infinity, that means
connection between the main board and wire plug
have problem. the detailmethod as above.
The solution for “E3”problem:
According to above two principle, to check both above

5.4 Whether the waterplate 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 beginstarting. which is anormal phenomenon; also the uneven
placing would lead to too much running noise.
There is a peculiar
smell in the units

◆ The solution for the common problem.
1.Cooling is not enough good
(Many reasons might cause that cooling not enough good, as blow :)
Reason analysis 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 coppertube 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 extragas 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.

than norm.
b, higher temperature of condenser.
c, larger electric currentof compressor
d, theremaybe ice on the suction tube.
e, when gas is too much, some gas
liquid might goes back into compressor,
compressor will be damaged by liquid.
3) There is air in the
liquid cycle system
The air in system will cause lower
efficiency of cooling.
Phenomenon of failure:
a, higher pressure of liquid cycle system
than norm, but the pressure is not over
the limit.
b, higher temperature of discharging
tube.
C, muchnoise
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.
4)Low working
efficiency of
compressor
General when a compressor works for
many years, some parts of compressor
were wear, so thatcompressor
discharge less gas out, unit does not
work strongly.
Phenomenon of failure:
a, lower pressure of discharging, check
the pressure of system with pressure
meter to see if it is normal.
b, higher temperature of compressor
surface.
C, cut off the discharging tube, to see if
you can block the gas coming out of the
tube when compressor is working.
Change a new compressor.
5) Thereis
something that
blocked the liquid
cycle system
Some time there is something blocked
the filter of liquid cycle system, so that
unit is not cold.
Phenomenon of failure:
a, lower pressure of discharging
b, lower temperature of discharging.
Change a new filter
2.NO COOL
(Popular failure reasons are below):
Reason analysis Solutions:
1) Leakage of gas
Phenomenon of failure:
a, leaking fast
b, leakingslowly
c, novoice of liquid flowing
d, cut off charging tube, no gas
goes out.
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)There is some
thing thatblocked
the liquidcycle
system
A,Ice blocking
Sometime because unknown
reason water comes into liquid
cycle system, the capillary will
be blocked by water after unit
runs for period of time.
Phenomenon of failure:
The unit works well in the
First stop unit for several minutes, and
then open charging tube,discharge all
of gas. Blowthe cycle system with gas
of nitrogen, and then recharge Gas,
finally sealed the system.

inception, after period of time
the iceappears in the capillary
and becomes more and more,
till blocks the hole of capillary
completely.In the moment you
can find the ice on the
evaporator defrosts.The noise
of liquid flow disappears. The
pressure ofabsorbing becomes
negative. The phenomenon
above will appear again and
again.
The way to check ice blocking:
Warm the capillary with a hot
towel, after a while the ice in the
capillary melt, you can hear a
sound ofgas flowcomes from
the capillary abruptly.The
pressure ofabsorbing becomes
higher. It is Ice blocking.
B, there is offal block the
capillary
Phenomenon of failure:
If thecapillary isblocked by
something such as offal etc.,
the sound of liquidflow
disappears.
The iceon the evaporator
defrosts
The pressure of absorbing
becomes negative.
Higher temperature of
discharging tube
The way tocheck offal blocking:
If you warm capillarywith the
way of checking ice blocking,
there is no change. Itmust be
offal blocking.
First stop unit for several minutes, and
then open charging tube,discharge all
of gas. Blowthe cycle system with gas
of nitrogen. Change a new capillaryand
filter, and then recharge Gas, finally
sealed the system.
COMPRESSOR NEVER STOPS：
Reason Solutions
1)The setting temperature is not reasonable. Readjust the temperature setting.
2) the sensor is bad. Replace the sensor.
3)Seal of door is damaged. Replace the gasket
4)Too much food in the refrigerator Please put the food properly.
5)Wind door is broken. Replace wind door.
6)Fan motoris broken. Replace fan motor
