DISASSEMBLY & REASSEMBLY
3-1) PRECAUTION
• Unplug the refrigerator before cleaning and making repairs.
• Do not dissemble or repair the refrigerator by yourself.
- You run risk of causing a fire, malfunction and/or personal injury.
• Remove any foreign matter or dust from the power plug pins.
- Otherwise there is a risk of fire.
• Do not use a cord that shows cracks or abrasion damage along its length or at either end.
• Do not plug several appliances into the same multiple power board. The refrigerator should always be
plugged into its own individual electrical which has a voltage rating that matched the rating plate.
- This provides the best performance and also prevents overloading house wiring circuits, which could
cause a fire hazard from overheated wires.
• Do not install the refrigerator in a damp place or place where it may come in contact with water.
- Deteriorated insulation of electrical parts may cause an electric shock or fire.
• The refrigerator must be grounded.
- You must ground the refrigerator to prevent any power leakages or electric shocks caused by current
leakage from the refrigerator.
• Do not put bottles or glass containers in the freezer.
- When the contents freeze, the glass may break and cause personal injury.
• Do not store volatile or flammable substances in the refrigerator.
- The storage of benzene, thinner, alcohol, ether, LP gas and other such products may cause
explosions.

TROUBLE SHOOTING
When the display is converted to Option Setting mode, the entire display is to be turned off except the
Fridge & Freezer 7-SEG LEDs as follows.
Option Value
Option Item
1) The following shows the way to shift the Freezer temperature by -3 This function is to shift its base
temperature. For example, if the current base temperature is -18 and it is lowered by -3 with the
Option Setting function, the unit is to be controlled based on -21° that is even though it shows -18
on the display panel after shifting the base temperature, it is to be controlled based on -21 So,
when the base temperature is lowered by -3 , the unit is controlled -3°… lower than the displayed
temperature.
NOTE The units are shipped out with all their data being cleared. i.e. the setting values are "0" for all
together. But, for the purpose of quality improvement, the settings can be changed before
being shipped out, make sure to check relevant SVC bulletins.
2) With the Option Setting mode, "0" blinks on both of the Fridge and the Freezer sections. (Generally,
they are set to "0" at both the Fridge and the Freezer sections. But, they can be changed for the
purpose of quality improvement.) - When "0" blinks on the Fridge section, it is set to the Freezer
Option Setting and the Freezer temp code will be displayed on the Freezer temp section.
3) If the Freezer temp code is set to "6" as the following table after setting the Fridge section to "0", the
Freezer base temperature is to be lowered by -3 (Refer to the Freezer temperature setting image.)
Option Value
Option Item
: In 15 seconds after completing the adjustment, MICOM is to store the setting value in EEPROM and
it goes back to the normal display mode, deactivating the Option Setting mode.
4) The above Option Setting is the same for both of the Dispenser model and the No-Dispenser model.
5) With the same method as the above, you can control the Fridge temperature, the water supply
quantity, the Ice-Maker sensor temperature.
6) Make sure not to change the factory-set default values otherwise exception cases. Also, the Option
Setting is to be completed when it goes back to the normal display mode in 20 seconds. So, do not
turn off the unit before it goes back to the normal display mode.
NOTE There are more functions which can be adjusted. But, they are not to be described in this
manual because they are not actually related to the diagnosis of the unit. (Do not change the
option settings other than the ones described in this manual)

4-2-5) When Fan does not operate
- A BLDC Fan Motor is applied to this refrigerator.The BLDC motor runs on DC8~12V.
- The F-Fan motor runs together with the compressor. But, due to conditions, the F-Fan Motor does not operate.
Also, when the ambient temperature is high and the Door is open and closed, the F-Fan operate after one minute.
So, it needs addition checking before considering it as a defect.

Note
Pulse signals being generated when the motor is rotating are to be input to CN74 #7(F), and #5(C).
These will be input to MICOM and when there are no signals with the motor rotating, the fan will be
turned off and then be turned on in 10 seconds.
If there are still no signals, it keeps trying the above 4 times. And, if it still fails, it runs the motor in 10
minutes. It is implemented to prevent the motor from being overloaded due to restrictions by foreign
substances such as ice built up around the motor.

Possible Causes
1. Defective FAN-MOTOR
2. Contact problem at the terminal
3. Check the motor rotating pulse input upon Fan Motor operation.
(Refer to Fan-Motor Circuit in this manual)
TROUBLE SHOOTING
4-2-6) Freezer / Fridge Lamp does not light up
Caution
1. When replacing the Freezer Lamp, be sure to turn off the power to prevent electric shock.
2. Take care when replacing the incandescent lamp to prevent skin burn.
Note
When the F-Door is open, its Door S/W will be open. And then 5V is to be applied to MICOM, signalling the Door Open.
After that, when 5V is input for more than 2 minutes, it will send out Door Open alarm for 10 seconds at an interval of 1
minute. (it's the same for the R-Door and the R-H/B Door.) So, when the Door S/W is defective, it will send "Ding
Dong" sound at an interval of 1 minute with the doors closed. In this case it needs repairing.
When the lamp is controlled with Relay

REFERENCE INFORMATION
7 -2 ) Q & A
Problem
The refrigerator does not
work sufficiently or at all
The food in the
refrigerator is frozen
Unusual noises or sounds
are heard
The front corners and
sides of the cabinet are
hot; condensation occurs
Ice is not dispensed
You can hear water
bubbling in the refrigerator
There is a bad smell in the
refrigerator
Frost forms on the wall of
the freezer
No water is supplied
Possible Causes
What To Do
• Check that the power plug is properly
connected.
• Disconnected power plug
• Is the temperature control on the display
panel set to the correct temperature?
• Try setting it to a lower temperature.
• Is the refrigerator in direct sunlight or
located near a heat source?
• Is the back of the refrigerator too close to the
wall?
• Is the temperature control on the display
panel set to the correct temperature?
• Is the temperature in the room too low?
• Did you store the food with a high water
content in the coldest part of the refrigerator.
• Move the refrigerator to the proper location.
• Is the back of the refrigerator too near to the
wall?
• Was anything dropped behind or under the
refrigerator?
• A “ticking” sound may be heard from inside
the refrigerator. This is normal and occurs
because various accessories contract or
expand.
• Try setting it to a warmer temperature.
• Check that the floor is levelled and stable.
• Move the refrigerator to the proper location.
• Remove the foreign thing.
• HOT-PIPE is installed in the front corners of
refrigerator. That makes refrigerator’s
temperature low quickly and save the power
consumption.
• Condensation can occur when you leave the
door open for a long time.
• Normal state
• Did you stop the ice making function?
• Is there any ice in the storage unit?
• Is the water pipe connected and the shut-off
valve open?
• Is the freezer temperature too warm?
• Did you wait for 12 hours after installation
of the water supply line before making ice?
• See the control panel.
• See the ice container.
• See the valve.
• The bubbling comes from the refrigerant
