CHAPTER 8. FAILURE DIAGNOSIS

[1] OUTLINE OF CONTROL

1. ON/OFF Control of Compressor

• ON/OFF of the compressor will be controlled depend on the temperature detected by

the R-thermistor and F-thermistor. (Normal cooling control)

• In case the surrounding temperature is high at the power supply input, the compressor will be ON at once and the normal cooling control will start
after several hours.

• When the rapid ice making or rapid freezing is requested by user during the operation, the compressor will be ON and cooling operation will be
started regardless of the detected temperature by the thermistors. However, if requested during the defrosting operation, the request will be exe­cuted after the completion of defrosting and ON of the compressor might be delayed.

• During 5 minutes after the compressor stops, it will not start regardless of the detected temperature by R-thermistor and F-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 about 50 hours, minimum time 8 hours)

3. Thermistor

Thermistors are installed in 4 places; in the refrigerator and freezer compartment, and close to the Control panel and Evaporator. (R-thermistor, F­thermistor, Outside temp-thermistor, Def-thermistor)

R-thermistor and F-thermistor detects the temperature in the refrigerator and freezer compartment respectively and controls ON/OFF of compressor.

Def-thermistor detects the temperature around the evaporator and shows the progress of defrosting.

Outside temp-thermistor detects the surrounding temperature of refrigerator. It decides the defrost timing and changes the operation mode when the
outside temperature is high.

[2] WHEN THE DEFROSTING FAILURE IS DOUBTFUL

Execute the Self-Diagnosis Mode. (Refer to the Chapter “SELF-DIAGNOSIS MODE”)

• In case the diagnosis result is “EE03” (Def-thermistor system defect), follow up the flowchart of EE03. (In case of any abnormity in the Def-ther­mistor, defrosting will not be made for safety reasons.)

• In case the diagnosis result is “EE07” (Defrost defect), follow up the flowchart of EE07.

(This diagnosis result will be displayed when defrosting is made for 120 minutes, the maximum time length. In this case, the defect of PWB itself
and also the breakage of heater and heater circuit (melt down of current fuse and temperature fuse) are considerable.)

[3] RE-SETTING OF MICROCOMPUTER AT POWER FAILURE

• At the power failure for over 0.4 second, the control of the microcomputer will might be reset.

• Microcomputer might continue to operate for approximately 10 seconds maximum at power failure depending on the load at the operation. Approx­imately 30 seconds is necessary for the definite power OFF condition.

• When the power is re-supplied, the normal cooling will be resumed.(If cold enough in the cabinet, the microcomputer will begin defrosting in 40
minutes according to the condition.)

• The temperature and operation mode set by user will be maintained even if a power failure occurred.

(However defrosting, rapid freezing, rapid ice making, and timer will not be maintained.)

• When the self diagnosis is made, each mode and setting are resumed to the initial condition.

SJF800SPSL

8 – 2

[4] DIAGNOSIS METHOD OF FAILURE AROUND PWB

First of all, check by using the self-diagnosis.

In case that the power supply doesn't enter, 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.)

• Under the condition of power supply plug connected;

In case of no cooling and no indoor lamp lighting, there might be a possibility of fuse (F1 or F2) melt down.

When the fuse F1 or F2 is melt down, PWB does not operate at all.

When the fuse F3 is melt down, defrosting heater and refrigerator door heater are not electrified. (Defrosting error will be diagnosed as
“Defrosting failure” by the self diagnosis.) In this case, the cooling performance may deteriorate or dew generation may occur on the door,
because the defrosting is not done.

• 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 “CN4” on the PWB and measure the resistance between 1 and 2 pins of harness side.

5. Check whether the temperature (resistance value) shown by Def-thermistor is correct or not. (Refer to the table below.)

• Detach the connector “CN5” on the PWB and measure the resistance value between 6 and 7 pins of harness side.

6. Check whether the temperature (resistance value) shown by F-thermistor is correct or not. (Refer to the table below.)

• Detach the connector “CN5” on the PWB and measure the resistance value between 4 and 5 pins of harness side.

Var is tor

Normal (over approx.1.5MΩ) Damage

Fuse

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 other check
item.

CHAPTER 9. SELF-DIAGNOSIS MODE

1. Entering method of the mode

1) Press the [Select] button on the LCD panel over 5 seconds at the opening condition of the
freezer and refrigerating room doors.

2) With a beep sound of buzzer, the self-diagnosis mode is entered. When the self-diagnosis
mode is not entered by the above operation, defect of Reed SW system can be considered.

2. When the self-diagnosis mode is entered, the following movements will be made. Forced release operation is not prepared for the self-diagnosis
mode. It returns to the normal movement after a lapse of 2 minutes.

• During the express ice making, express freezing or timer, the mode is released.
