CHAPTER 6. 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.
• 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 50 hours, minimum time 40 minutes)
3. Thermistor
Thermistors are installed in 4 places; in the refrigerator and freezer compartment, and on the Main PWB and close to Evaporator. (R-thermistor, Fthermistor, Outside temp-thermistor, Def-thermistor)
R-thermistor and F-thermistor reads the temperature in the refrigerator and freezer compartment respectively and controls ON/OFF of the compressor and OPEN/CLOSE of the electrical damper.
Def-thermistor detects the temperature around the evaporator and shows the progress of defrosting.
Outside temp-thermistor reads the surrounding temperature of refrigerator. It changes the operation mode when the outside temperature is high.
[2] WHEN THE DEFROSTING FAILURE IS DOUBTFUL(Only for SJ-PT51R/PT55R)
Execute the Self-Diagnosis Mode. (Refer to the Chapter “SELF-DIAGNOSIS MODE”)
• In case the diagnosis result is “ 03” (Def-thermistor system defect), follow up the flowchart of 03. (In case of any abnormity in the Def-thermistor, defrosting will not be made for safety reasons.)
• In case the diagnosis result is “ 07” (Defrost defect), follow up the flowchart of 07.
(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 0.2 second, the control of the microcomputer will be reset.
(Microcomputer might continue to operate for approximately 10 seconds maximum at power failure depending on the load at the operation. When
you need the difinite power off condition ,approximately 30 seconds is necessary.)
• When the power is re-supplied, the normal cooling will be resumed.
• The temperature set by user is not maintained if a power failure occurred.(Only for SJ-PT51R, PT55R)
(Defrosting also is not maintained.)
• When the self diagnosis is made, each mode and setting are resumed to the initial condition.(Only for SJ-PT51R, PT55R)

6 – 2
[4] DIAGNOSIS METHOD OF FAILURE AROUND PWB
In case of any abnormality of refrigerator, 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) melt down.
In case of cooling but no indoor lamp lighting, there might be a possibility of fuse (F2) melt down.(Only for SJ-T51R, T55R)
(However, these indications do not conclude the cause of the defect.)
When the fuse F1 is melt down, PWB does not operate at all.
When the fuse F2 is melt down, indoor lamp bulb and defrosting heater are not electrified. (It will be diagnosed as “Defrosting failure” by the
self diagnosis.)
• 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/
CN301” 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.

2) SJ-T51R / T55R

4. Check whether the temperature (resistance value) shown by R-thermistor is correct or not. (Refer to the table below.)
• Detach the connector “CN9/CN309” 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 “CN10/CN310” on the PWB and measure the resistance value between 6 and 7 pins.
6. Check whether the temperature (resistance value) shown by F-thermistor is correct or not. (Refer to the table below.)
• Detach the connector “CN10/CN310” on the PWB and measure the resistance value between 4 and 5 pins.

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.
