CAUTIONS
OBSERVED
WHEN
SERVICING
Unlike many other appliances, the microwave oven is high-voltage,
high current equipment. Though it is free from danger in ordinary
use, extreme care should be taken during repair.
PRECAUTION: :
Sayicanien should remove their wwatthes whenever working
plese to or replacing the magnetron.
8-1. Check the ground.
Do not operate on a 2-wire extension cord. The microwave
oven is designed to be used when grounded. It is imperative,
therefore, to make sure that the oven should be grounded prior
to repair.
8-2. Warning about the electric charge in the high voltage
capacitor
As an electric charge in the high voltage capacitor remains for
about 30 seconds after operation stops, short the current
between the oven chassis and the negative terminal of the
high voltage capacitor, by using a screwdriver before replacing
or checking parts.
er : Touch chassis side first then short to the high voltage
capacitor terminal by using a screwdriver or jumper
wire.
8-3. When parts must be replaced, remove the power plug
from the outlet
8-4. When the 1.6 Amp fuse is blown out by the operation of
the interlock Monitor switch:
(A) Replace the primary, door sensing and interlock monitor
switches. This is mandatory. Refer to page 8 for the necessary
adjustments of these switches.
(B) When replacing the fuse, confirm that it has the appropriate
rating for this model.
8-5. Avoid inserting any foreign materials, etc. through any
hole in the unit during operation.
Never insert any foreign materials or any other metal object
through the lamp hole on the cavity or any other holes or gaps,
because such objects may work as an antenna and cause
microwave leakage.
8-6. Confirm after repair:
(A) After repair or replacement of parts, make sure that screws of
the oven are neither loose nor missing; to prevent the
microwave leakage.
(B) Make sure that all electrical connections are tight before
inserting the plug in to the wall outlet.
(C) Check for radiation leakage. (Refer to the procedure for
measuring energy leakage in page 9.)
_ PRECAUTION
There exists HIGH VOLTAGE ELECTRICITY. with high. current
capabilities in. the -circuits.of the HIGH. VOLTAGE
TRANSFORMER secondary and filament terminals. it is
extremely dangerous to work on or near these circuits with the
oven energized.

8. Component Test Procedure
PRECAUTION
1. High voltage is present at the high voltage terminal of the high
voltage transformer during any cook cycle.
2. It is neither necessary nor advisable to attempt measurement
of the high voltage.
3. Before touching any oven components, or wiring, always
unplug the oven from its power source and discharge the high
voltage capacitor. : :
12-1. High Voltage Transformer
1} Remove connectors from the transformer terminals and check
continuity.
2) Normal resistance readings should be as follows:
Secondary Approx. 94Q
Filament Approx. 092
Primary... ... Approx. 1.7Q
(Room temperature = 20°C)
Filament Terminals
Secondary Terminat
Primary
Terminals
12-2. Low Voltage Transformer ‘
The low voltage transformer is located on the control circuit
board.
1) Remove the low voltage Transformer from the PCB Ass'y and
check continuity.
2) Normal resistor reading should be as follows.
Terminals Resistance
12-3. Magnetron
Continuity checks can only indicate an open fitament or a shorted
magnetron. To diagnose an open filament or shorted magnetron;
1) lsolate the magnetron from the circuit by disconnecting its
leads.
2) A continuity check across the magnetron filament terminals
should indicate one chm or less.
3) A continuity check between each filament terminal and
magnetron case should read open.
Magnetron Antenna
Gasket Plate
12-4. High Voltage Capacitor
1} Check continuity of the capacitor with meter set at the
highest ohm scale.
2) Once the capacitor is charged, a normal capacitor shows
continuity for a short time, and then indicates 9MQ.
3) A shorted capacitor will show continuous continuity.
4) An open capacitor will show constant MQ.
5} Resistance between each terminal and chassis should read
infinite.
12-5. High Voltage Diode
1) Isolate the diode from the circuit by disconnecting its leads.
2) With the ohm-meter set at the highest resistance scale,
measure the resistance across the diode terminals. Reverse the
meter leads and read the resistance. A meter with BV, SV or
higher voltage batteries should be used to check the front-to
back resistance of the diode, otherwise an infinite resistance
may be read in both directions. The resistance of a normal
diode will be infinite in one direction and several hundred KQ
in the other direction.
12-6. Main Relay and Power Control Relay
The relays are located on the PCB Ass’y.
1) Isolate the relays from the main circuit by disconnecting the
leads.
2} operate the microwave oven with a water load in the oven and
the power level set to high.
3} Check continuity between terminals of the relays after the start
pad is pressed.

10. Leakage Measuring Procedure
14-1. Equipment
* Microwave Energy Survey Meter
* 600cc glass beaker
* Mercurial or digital thermometer 100°C or 212°F
14-2. Procedure for Measurement of Microwave Energy
Leakage
1) Pour 27541 5cc of 2045°C (6849°F) water in a beaker which is
graduated to 600cc, and place the beaker in the center of the
oven.
2) Start to operate the oven and measure the leakage by using a
microwave energy survey meter.
3) Set survey meter with dual ranges to 2,450MHz.
4) When measuring the leakage, always use the 2 inch spacer
cone with the probe. Hold the probe perpendicular to the
cabinet door. Place the spacer cone of the probe on the door
and/or cabinet door seam and move along the seam, the door
viewing window and the exhaust openings moving the probe
in clockwise direction at a rate of 1 inch/sec. If the leakage
testing of the cabinet door seam is taken near a corner of the
door, keep the probe perpendicular to the areas making sure
that the probe end at the base of the cone does not get closer
than 2 inches to any metal. If it gets closer than 2 inches,
erroneous readings may result.
5) Measured leakage must be less than SmW/cm?, after repair
or adjustment.
14-3. Check for Microwave Energy Leakage with Outer
Panel Removed.
1) Remove the outer panel.
2} Pour 275-41 5cc of 2045°C(6849°F) water in a beaker which is
graduated
to
600cc,
and
place
the
beaker
in
the
center
of
the
oven.
3) Start to operate the oven at the highest power level.
4) Set survey meter with dual ranges to 2,450MHz.
5) By using the survey meter and spacer cone as described
above, measure around the opening area of magnetron, the
surface of the air guide and the surface of the wave guide as
shown in the following photo but avoid the high voltage
components. The meter should read fess than SmW/cm?,
Survey Meter
WARNING -
AVOID THE HIGH VOLTAGE COMPONENTS.
14-4. Note on Measurement
1) Do not exceed the limited scale.
2) The test probe must be held on the grip of the handle,
otherwise a false reading may result when the operator's
hand is between the handle and the probe.
3) When high teakage is suspected, do not move the probe
horizontally along the oven surface; this may cause damage
to the probe.
4) Follow the recommendation of the manufacturer of the
microwave energy survey meter.
14-5.
Record
keeping
and
notification
after
measurement
1) After adjustment and repair of a radiation preventing device,
make
a
repair
record
for
the
measured
values,
and
keep
the
data.
2) If the radiation leakage is more than 5mW/cm? after
determining that all parts are in good condition, functioning
properly
and
the
identical
parts
are
replaced
as
fisted
in
this
manual, notify that fact to;
CENTRAL SERVICE CENTER
14-6.
At
least
once
a
year
have
the
Microwave
Energy
Survey Meter checked for accuracy by its
manufacturer.
