1. Precautions
Warning : Please abide by the following
precautions in order to conduct
the maintenance procedures in a
safety fashion.
Cleaning : After completing repairs, clean
the surrounding area and the
refrigerator and tell the consumer
about the repairs being made.
This appliance contains a small amount of the
refrigerant isobutane(R600a), a natural gas with high
environmental compatibility but which is also
combustible. When transporting and installing
the appliance, care should be taken to ensure
that no parts of the refrigerating circuit are damaged.
Refrigerant squirting out of the pipes could ignite or
cause an eye injury. If damage occurs nevertheless,
avoid any flames or potential sources of ignition, and
air the room in which the appliance is standing for
several minutes.
1-1. Caution when you replacing compressor.
• Do not smoke. Remove all the possible ignition
sources and then replace compressor in wellaired places.
• Don’t use welding machines if R600a refrigerant
does not exposed.
• In the case of gas leakage, always open the
windows.
• When cutting the SUCTION, DISCHARGE pipe
of the compressor, always take caution of the
inner pressure of the remaining gas.
• In order to avoid the creation of a flammable gas-air
mixture if a leak in the refrigerating circuit occurs, the size
of the room in which the appliance may be sited depends
upon the amount of refrigerant used. The room must be
1m3 in size for every 8 g of refrigerant R600a inside the
appliance. The amount of refrigerant contained in your
particular appliance is shown on the identification plate
inside the appliance.
• Never start up an appliance showing any signs damage. If
in doubt, consult your dealer.
1-2. Take out the power plug
• Always take out the power plug from the outlet
when doing repairs.
1-3. Be careful of electric shocks
• When inspecting the circuit, don’t touch the
battery charger and be careful of electric
shocks.
1-4. Use proper components
• Always use the component labeled in the
service component chart when replacing
components for repairs.
Refers to prohibition.
1-5. Use proper tools
Refers to prohibition of dismantling.
• Always use proper tools for repairs. If worn out
tools are used, it would cause defects in tuning
and electrical contact, leading to accidents.
Refers to prohibition of contact.
1-6. When doing repairs, inspect the POWER
Refers to guidelines which have to
be followed.

CORD or whether there is fire in the lead wire
and make sure they are replaced.
1-7. Cutting of LEAD-WIRE
• For connecting the lead-wire that has been cut
off, use soldering or connector and always
disconnect the vinyl tapes.
1-8. Check for disconnection
• After completing the assembly, always measure
the disconnection resistance level, and turn on
the power after checking it is above 1MΩ.
Refers to possibility of death
or serious injury of a person.
1-9. Earth

will blink.
b) If refrigerator inner temperature is above 15˚C for 10 minute, the display of the selected
temp. will blink.
c) When quick freeze is chosen, only freezer display will display actual temperature and the
actual temperature displays up to -35˚C.
17
3) Door open
when door is open, the related display shows an actual temperature.
3-1) Display range of freezer is -35˚C ~ 30˚C and refrigerator is -9˚C~9˚C.
3-2) If freezer inner temperature is above 0˚C for 10 minute, the display of the selected temp.
will blink.
3-3) If refrigerator inner temperature is above 15˚C for 10 minute, the display of the selected
temp. will blink.
3-4) When door is open, 1˚C will increase after delay time from the display before door
opens. When door close, 1˚C will decrease after delay time if there is a change in inner
temperature. Temperature will reach up to presently selected notch.
4) Defrost Display function
4-1) If defrost starts both freezer and refrigerator display the selected temperature. So it will
not blink for 2 hours even if it sensed faulty in inner temperature, after 2 hours it will
decide to blink or not.

Power around MICOM & Sensor Detector
1) The input AC voltage of DC-trans secondary registers 8V at CN10 between ①~③. The rectified
voltage passed through D101 ~ 104 becomes DC 5V through voltage regulator MC7805(REG1).
The power(DC5V) is supplied to the power around micom and sensor detector.
2) The input AC Voltage of DC-trans secondary registers 15V at CN10 between ⑤~⑦. The rectified
voltage passed throush D105 ~ D108 becomes DC 12V through voltage regulator MC7812CT
(REG2). The power (DC12V) is supplied to the relay operation and LED display.

When power is supplied to MICOM, reset circuit
initializes RAM and other parts on MICOM to
initialize all programs. Reset voltage maintains “low”
for hundreds of µsec comparing to MICOM Vcc
voltage when power is input. It also maintains
“high”(5V) during normal operation. But, when Vcc
drops to 3.4V-3.7V, reset port becomes “low”.

1) The sensor uses the characteristics of thermistor. If temperature goes higher, resistance goes
lower. On the contrary, if temperature goes lower, resistance goes higher.
2) MICOM input voltage is counted by sensor as follows.
RTH
(VCC : 5V, RTH : Sensor reisitance)
VF =

6-6. Button scan and display circuitry
At that time, the peak to peak voltage of square signal registers around 12V. The grid #1 ~#5
waveforms are as follows.
22
6-7. Load Operation
If MICOM outputs “high” signal to driver-IC(KID65003AP/S1P2655AØ3) according to each load
operation conditions, IC turns on and DC 12V flows to ground through the relevant relay coil. Then,
core is magnetized by the coil current, and relay contact switches on. When relay contact is on, AC
POWER is supplied to the relevant operation load, then which will be activated. If MICOM outputs
“low” signal, load operation stops with the relevant relay contact off.

Like the above block diagram, operation of F, R defrost heater is detervminedy according to the
operation of relay for COMP. When comp relay is connected to NO terminal, comp operates.
However, in case of F, R defrost heater, electricity dose not pass through the heater though relay
works, But, if Comp relay is connected to NC terminal, comp does not operate and heater gets
electrieity according to operation of F, R defrost relay.

12-1 Regulator
3-TERMINAL 1A POSITIVE VOLTAGE REGULATORS
The MC78XX/MC78XXA series of three-terminal positive regulators are available in the
TO-220 package and with several fixed output voltages, making it useful in a wide range
of applications. These regulators can provide local onward regulation, eliminating the
distribution problems associated with single point regulation. Each type employs internal
current limiting, thermal shut-down and safe area protection, making it essentially
indestructible. If adequate heat sinking is provided, they can derive over aA output
current. Although designed primarily as fixed voltage regulators, these devices can be
used with external components to obtain adjustable voltages and currents. MC78XXI is
characterized for operation from -40°℃ to +125℃, and MC78XXC from 0℃ to +125℃.
