CHAPTER 6. FAILURE DIAGNOSIS
[1] OUTLINE OF CONTROL
1. ON/OFF Control of Compressor
When the plug of refrigerator is connected, the compressor will start automatically and run for approximately 5 minutes. After then, ON/OFF of the
compressor will be controlled depend on the temperature detected by the R-thermistor. During 6 minutes after the compressor stops, it will not start
regardless of the detected temperature by R-thermistor..
2. Defrosting
Microcomputer calculates the appropriate timing of defrosting and defrosting is made automatically. Therefore no manual operation by user is
required. The cycle of defrosting varies depend on the usage condition of the refrigerator. (Maximum time 50 hours, minimum time 4 hours)
3. Thermistor
Thermistors are installed in 2 places; in the refrigerator compartment and close to the
Evaporator. (R-thermistor and Def-thermistor)
It is not installed in the freezer compartment.
R-thermistor reads the temperature in the refrigerator compartment and controls ON/OFF
of compressor.
Def-thermistor detects the temperature around the evaporator and shows the progress of
defrosting.
[2] CHECK MODE OF DEFROST HEATER (Forced Defrosting)
The operation of the defrost heater can be checked by starting it.
In case the failure of defrosting is suspected, this is an effective inspection method.
1. Starting Method
At the power OFF condition.
1) Keep the door of the refrigerator compartment open.
2) Set the Temp. Control Knob in the refrigerator compartment to the following position.
220-240V models: Center
110-127V models: Max
3) Keep the door open and supply power source.
2. Normal Operation
1) Approximately 3 seconds after power supply, the relay on the PWB will be turned ON and the defrost heater will be electrified for 5 seconds.
2) After 5 seconds, if the temperature of Def-thermistor reaches high enough (over 10°C) and judged as defrosting completion, the compressor runs
for 5 minutes and then returns to the normal control.
On the other hand, if the temperature of Def-thermistor is still low (under 10°C), the defrost heater will be electrified until the temperature of Def-
thermistor reaches the specified temperature or higher.
After completion of electrification, the compressor runs for 5 minutes and then returns to the normal control.
* In the case that any abnormality in Door Switch, Volume, R-thermistor or Def-thermistor, or the Temp. Control Knob is not in the position corre-
sponding to the value of the rating voltage settled to the PWB itself, this mode will not be entered nor the defrost heater is electrified.

[3] RE-SETTING OF MICROCOMPUTER AT POWER FAILURE
• At the power failure for over 0.1 second, the control of the microcomputer will be reset.
When the power is re-supplied, the temperature of R-thermistor will be detected again and ON/OFF of the compressor will be decided.
• At the momentary power failure (less than 0.1 second), the protector of the compressor might work due to the high load to the compressor for restarting.
• When resetting is made during the operation of the defrost heater, the normal cooling will be resumed.
[4] DIAGNOSIS METHOD OF FAILURE
Check by the following procedure;
1. Disconnect power supply and check the following point.
• Is there any failure portion in inserting connectors?
2. Detach the PWB and check the appearance.
• Is there any burning or abnormal damage?
3. Check the conditions of the fuse and the varistor. (Fuse and varistor are located at the position in the figure.)
• Melting in the fuse cannot be checked visually (as the safer one than transparent glass tube is used). Be sure to detach the connector “CN1”
before measuring the resistance between the both ends of the fuse by the tester.
• Next, measure the resistance value between the both leads of the varistor.
4. Check whether the temperature (resistance value) shown by R-thermistor is correct or not. (Refer to the table below.)
• Detach the connector “CN3” on the PWB and measure the resistance value between 1 and 2 pins.
5. Check whether the temperature (resistance value) shown by Def-thermistor is correct or not. (Refer to the table below.)
• Detach the connector “CN3” on the PWB and measure the resistance value between 3 and 4 pins.
Var isto r→
Normal (several hundreds Ω~several KΩ)Damage

Melting
Flow of excessive current is considerable for some reasons.
Check for any portion to cause short circuits especially
on the primary circuit.
There is a possibility of excessive voltage applied from outside with the factor such as thunder etc. When repeated
with a factor other than thunder, there might be the apparatus near by generating noises.
Conduction
Fuse and varistor are normal.
Possibility to be caused by excessive current or voltage
near the power supply is low. Proceed to the next check
item.

CHAPTER 7. FUNCTIONS
[1] ADJUSTABLE TEMPERATURE CONTROL
1. Temperature control
1) FREEZER COMPARTMENT
The FREEZER TEMP. CONTROL regulates the quantity of cold air to the freezer.
"MAX" setting directs more cold air to the freezer compartment. (making the freezer compartment colder)
"MIN" setting directs less cold air to the freezer compartment. (making the freezer compartment less colder)
2) REFRIGERATOR COMPARTMENT
The REFRIGERATOR TEMP. CONTROL controls the compressor running time of the refrigeration system.
"Coldest"(5) setting will result in colder temperature in the both (refrigerator and freezer) compartments.
"MIN"(1) control setting will result in warmer temperature in the both (refrigerator and freezer) compartment.
NOTE:
• For hot summer conditions (about over 35 °C ambient temperature), set your FREEZER TEMP. CONTROL to less colder than "MID"
(towards "MIN"). This is because "MAX" setting may result in too little air flow to the refrigerator compartment, causing too warm temperature in the refrigerator compartment. And set your REFRIGERATOR TEMP. CONTROL to colder than the center position.
• In a cold kitchen (about under 10 °C ambient temperature), set your FREEZER TEMP. CONTROL to "MAX" to avoid too warm tempera-
ture in the freezer compartment. This is because the compressor operation is too short in winter, and not enough cold air is provided to
the freezer compartment. And if the foods in the refrigerator compartment freeze, you must set the REFRIGERATOR TEMP. CONTROL to
less colder setting. (toward "MIN").
• With the FREEZER TEMP. CONTROL set to "MAX" , there will be less cold air directed to the refrigerator compartment, and the refrigerator compartment may not become cold enough.
2. Reference value of temperature
The values tables above refer to the measurement carried out center area and 1/3 of overall height from the bottom at each of the refrigerator and the
freezer after the machine has been operated at an ambient temperature of 32 °C with no food stored and the door closed until the temperature is sta-
bilized.
The values vary depending upon frequency of opening and closing, the doors ambient temperature, amount of stored foods and manner of storing
foods.
