issue alarms continuously until the said door is closed. The alarm can be stopped
when any key is pressed, but it will be restored after 3 minutes if the door keeps
open.

or not.
4. Other fault phenomena and maintenance methods
(1) The refrigerator does not work. (The whole machine is not working, with the
compressor not started, the display panel not illuminated and the LED lamp OFF
when the door is opened.)
a. Check whether the refrigerator plug is properly plugged in; whether the
socket is electrified; and whether the socket voltage is normal.
b. Cut off power supply, remove the electrical box cover, observing whether the
terminals are properly connected, reinsert the terminals, and then power on
the system to observe whether the refrigerator can work normally.
c. Cut off power supply, change the main board, insert the terminal well, and
power on the system to observe whether the refrigerator can work normally.
(2) The compressor cannot start. (Other devices are working normally)
The compressor shutdown during the normal operation of the refrigerator does
not belong to this type of failure. Be sure to wait for at least 5 minutes before
starting the compressor again in the case of compressor shutdown. During the
following maintenance operations, if a power failure occurs, please wait for 5
minutes, and then power on the system to observe the compressor working, or
wait for 5 minutes after the system is powered on to observe whether the
compressor can work normally or not.
a. Cut off power supply, remove the electrical box cover, check whether the
terminals are properly connected, insert them again, and then power on the
system to observe whether the compressor can start normally.
b. If it still cannot start, cut off power supply, remove the compressor cover, check

BCD-317W/351W (external display) Service Manual
15
whether the compressor protector is properly plugged in, reconnect it, and then
power on the system, observing whether the compressor can start normally or
not.
c. If it still cannot start, cut off power supply, replace the control board, and power
on the system after inserting well the terminal, observing whether the
compressor can start normally or not.
d. If it still cannot start, it is judged as the compressor fault, then replace the
compressor.
(3) LED lamp does not light up when the door is opened.
a. If the door open alarm occurs, check whether the door is closed and the door
lamp switch gets broken. (The LED lamp goes off when the door is open for
10 minutes.)
b. In the case of no door open alarm, cut off power supply, remove the electrical
box cover, check whether the terminals are properly connected, insert them
again, and then power on the system to observe whether the LED lamp lights
up;
c. If the LED lamp is still off when the door is opened, cut off power supply,
change the LED lamp, and then power on the system, observing whether the
LED lamp goes on.
(4) The freezer is cooling while the fridge is not cooling.
a. Hold down the combination keys of ‘Freezer and ‘OK’ for 5 seconds to enter
the maintenance program, turn on the compressor, fan and air damper by
force, turn off the defrosting heater, and then open the door, put your hand
at the air duct outlet, checking whether there is cooling air blown out from it.
b. If there is no obvious cooling air blown out from it, cut off power supply,
dismantle the fridge air duct assembly and the freezer air duct assembly, with
the terminals not removed, and then check
Whether there is frost jamming, whether there are heavy frosts formed
on the evaporator and air duct outlet. If yes, refer to the following Item
(8) .
Power on the system, and check whether the fan is normal by reference
to Item (6) .
Power on the system, enter the maintenance program, wait 2 minutes
before opening the air damper, and check whether the air damper can
be opened normally; if it cannot be opened normally, replace the air
damper; (It takes some time for the air damper to reset every time when
the system is powered on.)
c. Cut off power supply, replace the display panel, power on the system when

BCD-317W/351W (external display) Service Manual
16
the door is opened, close the door for cooling 10 minutes, and then open the
fridge door, hold down the door lamp switch, checking whether there is cool
air blown out of the fridge air outlet.
d. Cut off power supply, replace the main board, power on the system when the
door is opened, close the door for cooling 10 minutes, and then open the
fridge door, hold down the door lamp switch, checking whether there is cool
air blown out of the fridge air outlet.
After the maintenance is completed, assemble all components, power on the
system to perform Step a operations, ensuring there is cold air blowing out of the
cold room, and then cut off power supply before powering it on again.
(5) The refrigerator is not cooling.
Cut off power supply, remove the electrical box cover, check whether the
terminals on the main board are properly connected, insert them well again, and
then power on the system when the door is opened, wait for 10 minutes to
observe whether the refrigerator compressor can be started. If not, refer to Item
(2); and if yes, touch the left and right-side plates by hand to check whether they
are hot or not. If not hot, it is judged to be the refrigerant leakage fault, then
conduct vacuum pumping and charge the refrigerant again.
(6) The refrigerator air fan is not running.
a. Cut off power supply, remove the electrical box cover, check whether the
terminals on the main board are properly connected, insert them well again,
power on the system, hold down the combination keys of ‘Freezer’ and ‘OK’
for 5 seconds to enter the maintenance program; turn the fan on, open the
freezer door, and place your hand on the air duct to check if there is cool air
blown out.
b. Cut off power supply, remove the freezer air duct assembly, check whether
the terminals are properly connected, and whether there is such interference
as ice, wire harness or other foreign matter. If the terminals are loose or
detached, reconnect them well; if there is ice, perform the maintenance
program first to confirm whether the fan is in good condition or not. If yes,
refer to the operation of Item (7) ; and if there is the wire harness or foreign
object interference, reshape the wire harness or remove the foreign object.
Then, power on the system, hold down the combination keys of ‘Freezer’ and
‘OK’ for 5 seconds to enter the maintenance program, turn on the fan,
checking whether the fan can be started normally. If the fan cannot start,
replace the freezing air duct assembly, and enter the maintenance program
again to check whether the fan can be started normally.
c. Replace the main board, power on the system to enter the maintenance

BCD-317W/351W (external display) Service Manual
17
program, and turn on the fan, checking whether the fan can be turned on
normally.
(7) The refrigerator does not defrost.
a. Cut off power supply, remove the electrical box cover, and check whether the
terminals on the main board are properly connected.
b. After the power is cut off, remove the freezer air duct assembly, checking
whether the defrosting heater terminal is properly connected, whether the
terminal is sealed properly, and whether the terminal is in good condition.
c. After the power is cut off, remove the defrosting heater, and measure the
resistance of the defrosting heater with a multimeter to determine whether
the defrosting heater is damaged.
d. After the power is cut off, replace the main board.
e. After the power is cut off, replace the display panel.
How to check the heater.
1) Dismantle the freezer air duct assembly by referring to the disassembly method of
"freezer air duct assembly", unplug the heater terminal, and set the multimeter as
illustrated below to test the heater resistance:
Test results should be between 251 ~ 278 Ω(high voltage) or between62 ～70Ω(low
voltage) , beyond which the heater should be replaced.
