1) Self diagnosis in the initial power on
When a power is ON, if internal MICOM will decide faulty in temperature within 1 second.
If faulty sensor is found, the “related display LED” switches ON and OFF for 0.5 second intervals.
At the LED situation is the faulty sensor display, self-test function key (F room key + R room key for
11seconds) is the control of normal temperature is delayed.
Fixing default sensor when there is an error, or press F room key and R room key for 11 seconds, it
automatically cancel self-test function and activate normally.
2) Self diagnostics in the normal operation
If “ F-ROOM +R-ROOM” key is pressed for 3 seconds at the normal operation, temperature setting display
proceeds ALL ON/OFF by 0.5 second intervals foe about 4 seconds. If “ F-ROOM +R-ROOM” key is pressed
for 7 seconds including 4 seconds of ON/OFF, all displays proceed ALL ON/OFF by 0.2 second intervals for
about 4 seconds. If “ F-ROOM +R-ROOM” key is pressed for total 11 seconds including 4 seconds of 0.2
second intervals ON/OFF, all displays becomes ALL ON and “ “ buzzer occurred, and then start a self
diagnosis.
Self diagnosis is performed from “ colder-colder” LED with being OFF in sequence at the state that freezer
/refrigerator temperature setting displays are all ON.
In case of detection inferior sensor, the corresponding display lamp keeps up ON.

Reset circuit is that initializes many internal parts of the MICOM and makes the all programs to act in the initial
state in case that power is impressed to MICOM by instantaneous interruption or power input. Reset terminal
voltage becomes to scores of us “ LOW” compared to the MICOM Vcc((DC 5V) voltage on power
impression, and keeps “ HIGH” (Vcc voltage) on the normal action.

(10℃), and it detects F room door open/close by impressing to MICOM “ HIGH(5V)/LOW” . CN30 ℃ is
connected to GND and ① is supplied Vcc(DC 5V) by passing through resistance R403(10℃), and it
detects R room door open/close by impressing to MICOM “ HIGH(5V)/LOW” If there are some faults in
door S/W at this time, the corresponding fan is not act or alarm occurs. Check the door S/W whether it has
an abnormality. If the door is opened, the internal corresponding fan stops. This is occurred because
MICOM stops the fan deciding door open although door is closed when being S/W contact point
abnormality.

PIN #57 (F-DEF-SENSOR)
MICOM terminal
voltage is
PIN #58 (R-SENSOR)
changed by the
PIN #59 (ATMOSPHERE SENSOR) temperature.
PIN #56 (F-SENSOR)
Sensor makes use of the character that resistance value becomes smaller when temperature is high, and bigger
temperature is low by use of thermistor having a indeterminate resistance temperature coefficient. R302,4,6,8 and
C301,2,3,5 have no concern with temperature detection because they are for noise
protection parts. In case of F-sensor, if the voltage that input to MICOM is supposed to Vf, Vf= (Rth x Vcc)/(R301
+ Rth).At this, Rth is a thermistor resistance value. Refer to attached appendix for MICOM terminal voltage
corresponded to temperature and resistance/voltage conversion table of sensor.

10-6. Key scan and display circuit part
1) Description of key scan and display drive action
As a following each part wave, “ HIGH” output is send out, by use of three terminals of MICOM No #5,6,7 by
6 msec intervals. This signal passes through input terminal of IC05 and is displayed to output terminal. At this
time, the peak to peak voltage of rectangle wave is about 12V, the shape of output wave is like following.
2) KEY SCAN
When GRID #3 wave is output, this signal is supplied to SW1 by passing through panel PCB R5 resistance
10℃. At this time, pressing SW1 makes a signal small by R508(6.8㏀) and R505(12㏀), and impress peak to
peak 4.5V to MICOM. MICOM decides that GRID #3 wave is input and changes the function corresponding
to SW1. Like this, each GRID wave is recognized.
29
10-7. BLDC MOTOR drive circuit
● Movement description
When F-fan is driven to LOW RPM, Resetting the MICOM #40 pin with being set #39 always links
the R705 and R707 in a parallel. At this time, the voltage is devided between a parallel resistance
value and R706, impressed to OP-AMP. It makes Q1 turn ON, F-fan drive. If F-fan is in condition
of OFF, MICOM #39 pin is reset and F-fan is stopped. In case of the Comp.-fan, it is controlled by
the same method with F-fan. But its drive voltage is different with that because there is a
difference in E1 voltage /E2 voltage due to the difference of RPM.
※ Fan motor protection
When the fan is not run because of F-fan/C-fan freezing or power cord connection part inferiority,
fan self-signal is not occurred. So MICOM decides fan abnormality. At this time, perform the fan
three seconds ON, seven seconds OFF in five times. If there is no signal during the fan ON/OFF
five times, after 10 minutes pausing repeat the three seconds ON, seven seconds OFF in
five times.
If the signal is occurred during the three seconds ON, seven seconds OFF, MICOM decides that
operation is normal and releases all motor protect functions and performs a normal function.
30
10-8. Load drive part circuit
● Movement description
When “ HIGH” signal is impressed to input terminal of IC04 at MICOM PIN NO #15, IC turns ON. At this time,
V12(DC 12V) connected to one side end of Comp relay passes through output of IC04 to ground, and the
core of relay causes a magnetic field and makes a contact point on. And AC input voltage(AC 220V) is
impressed to the both side end of Comp. load, Comp. acts. In case of the MICOM PIN #15 signal is “ LOW” ,
IC04 turns off and the current is not flow to Comp. relay coil and makes a relay contact off. And Comp. stops.
The load except the compressor equals or likes to the act principal of compressor. Refer to the above circuit
diagram.
31
10-9. Damper motor drive part
● Movement description
Damper is a 2 excitation type stepping motor used in controlling the refrigerator temperature. It is opened
when the temperature is higher than the setting temperature of refrigerator sensor, and closed lower
according to the refrigerator notch.
It performs a open/close without regardless of refrigerator temperature at power ON, and then decides the
state of open/close according to the temperature.
Open/close action is controlled by MICOM #34, #35, #37 through damper motor(stepping-motor) exclusive
control drive IC(IC8:TA7774P).
Damper heater is supplied DC12V whenever voltage impresses to the refrigerator and the signal is occurred
always in MICOM #24, DC 12V flows into
the damper heater by IC3.
※ Note
In case of the above damper heater, because the PCB cannot detect the open/close state, there is no self
diagnosis function for deciding the abnormality. IN the above diagram, if a wire cut off linked 3,4,5 of CN7,
motor is run as a normal, but refrigerator over cooling occurs by slightly open at the
close of damper.
So, check for deciding of abnormality of damper motor connection part like followings.
1) Check method : After separation of CN72 housing, measure the resistance value by use of
multi tester and decide the abnormality.
2) Resistance value spec
①-② (black, brown) : 150Ω±15%
③-④ (white, blue) : 426Ω±15%
⑤-⑥ (yellow, red) : 426Ω±15%
