NECESSARY
TOOLS
AND
MEASURING
INSTRUMENTS
1. Necessary tools 2. Necessary measuring instruments
Tools normally used for TV servicing are sufficient. * Tester (Volt D.C/A.C - ohm meter)
Standard tools are listed below. * Ruler
* Diagonal pliers * Microwave energy survey meter
* Philips head screwdriver * 600cc glass beaker
* Socket wrench (SIZE 8, 15mm) * Glass thermometer 100°C or 212°F with alcohol
* Nutdriver (SIZE 5.5, 7.8mm) column.
* Solder * Two 1 liter beakers.
* Vinyl insulation tape
* Long-nose pliers
* Slotted head screwdriver
* Adjustable wrench
* Soldering iron
* Polishing cloth

p
1. For Safe Operation
Damage that allows the microwave energy(that cooks
or)
to
expose
will
result
in
poor
cooking
and
may
cause
serious injury to the operator.
IF ONE OF THE FOLLOWING CONDITIONS EXISTS,
THE
OPERATOR
MUST
NOT
USE
THE
APPLIANCE.
(Only
a
trained
service
personnel
should
make
repairs.)
(A)
A
broken
door
hinge.
(B) A broken door mesh plate.
(C) A broken front panel to oven cavity.
(D) A loosened door lock.
(E) A broken door lock. ‘
The
door
gasket
plate
and
oven
cavity
surface
should
be
kept
clean.
No
grease,
soil
or
spatter
should
be
allowed
to
build
up
on
these
surfaces
or
inside
the
oven.
DO
NOT
ATTEMPT
TO
OPERATE
THIS
APPLIANCE
WITH
THE
DOOR
OPEN.
Interlock
switches
are
con-
cealed
from
outside
in
order
to
avoid
being
touched
by
someone’s
mistake
so
that
the
operation
of
oven
stops
when
the
door
is
opened.
Be
coutious
not
to
break
them.
Notice
that
you
should
not
attempt
any
service
unless
you
read
this
service
manual.
roper Use and Precautions
2. Correct Installation
(A) This microwave oven weighs 36Kg and must be -
placed on a horizontal base strong enough to sup-
port the weight.
(B) The oven should be placed as far from high tempera-
ture heat source and vapour as possible.
(C) The power supply cord is 2m long. Grounding is
required
when
connecting
the
power
source.
(D)
Power
consumption
of
this
oven
is
approximately
2.9kW.
It
suggests
that
the
unit
is
operated
on
such
power
line
that
can
provide
more
power
than
this
rating.
(E) Objects must not be placed on the top enclosure
SO
as
not
to
obstruct
air
flow
for
ventilation.

Circuit Descriptions
Refer to the wiring diagram on page 16.
1. When the food is placed inside the oven and the
door is closed
(A) The low voltage transformer supplies necessary volt-
age to the touch control circuit when the power
cord is plugged in.
(B) The primary interlock switch and the secondary in-
terlock switch are closed.
(C) The interlock monitor switch is opened. This interlock
monitor switch acts to blow 15A fuse and stop mag-
netron oscillation when the door is opened during
operation under an abnormal condition. (i.e. the
contacts of primary interlock switch do not open
and the contacts of secondary interlock switch do
not close the circuit to stop oscillation)
(D) The door key is caught by the door hook, the door
sensing switch is opened to give touch control circuit
the information that the door is closed.
2, When cooking cycle, power and time are set by touch-
ing the function pads and the desired numerical pads
(A) Cooking function word shown on the display window
blinks to indicate the selected function.
(B) The time set appears in the display window.
(C) The touch control circuit stores the cooking data
set.
3. When the START pad is touched
The main relay and the power control relay are controlled
by the touch control circuit.
(A) An ovenlamp lights the inside of the oven by operation
of the main relay in the Touch Control Circuit.
(B) Fan motor rotates and cools the magnetron by blow-
ing the air coming from the intake on the back panel
over the magnetron fins. After cooling the fins, this
air is directed into the oven to blow out the vapor.
(C) 220VAC is applied to the high voltage transformer
through the contacts of primary and secondary
switches shown by the solid line just after the power
control relay turns ON. (Fig. 3)

(D) 3.3V AC is generated from the filament winding of the
high voltage transformer. This 3.3V is applied to the
magnetron to heat the magnetron filament through two
noise preventing choke coils.
(E) High voltage of 2,120 volts AC is generated from the
high voltage transformer secondary and this secondary
voltage is increased by the action of the diode and
the charging of the high voltage capacitor. This resul-
tant D.C. voltage is then applied to the anode of the
magnetron. As shown in the Fig. 4, the first half cycle
of the high voltage produced in the secondary high
voltage transformer charges the high voltage capacitor.
| AC S.3ViEUF FT RES FFs |
|MAGNETRON
(Fig. 4)
Current flow is in the direction of the dotted line. During
the second half cycle, the voltage produced by the
transformer secondary and the charge of the high volt-
age capacitor are combined and applied to the mag-
netron as shown by the solid line so that oscillations
begin. The disturbance wave generated from the mag-
netron is prevented by the chock coils of 1.6uH, filter
capacitors of 500pF and the magnetron shielded case
so that TV and radio programs are not impaired by
noise.
(F) The power contro! relay is turned on intermittently by
the touch control circuit, when the oven is set at any
power selection except for full power. The touch con-
trol circuit controls the ON/OFF time of the power con-
trol relay in order to vary the output power of the
microwave oven from “Low” to “Full” power. One com-
plete ON/OFF cycle of the power control is 30 seconds.
The relation between indications on the control panel
and the output power level of the microwave oven is
on the page 35.
