PRECAUTIONS TO BE OBSERVED BEFORE AND
DURING SERVICING TO AVOID POSSIBLE
EXPOSURE TO EXCESSIVE MICROWAVE ENERGY

- 1 -
1. Precaution
Follow these special safety precautions. Although the microwave oven is completely safe during ordinary use,
repair work can be extremely hazardous due to possible exposure to microwave radiation, as well as potentially
lethal high voltages and currents.
1. All repairs should be done in accordance with the
procedures described in this manual. This product
complies with Federal Performance Standard 21
CFR Subchapter J(DHHS).
2. Microwave emission check should be performed to
prior to servicing if the oven is operative.
3. If the oven operates with the door open :
Instruct the user not to operate the oven and con-
tact the manufacturer and the center for devices
and radiological health immediately.
4. Notify the Central Service Center if the microwave
leakage exceeds 5 mW/cm2.
5. Check all grounds.
6. Do not power the MWO from a “2-prong” AC cord.
Be sure that all of the built-in protective devices are
replaced. Restore any missing protective shields.
7. When reinstalling the chassis and its assemblies,
be sure to restore all protective devices, including:
nonmetallic control knobs and compartment covers.
8. Make sure that there are no cabinet openings
through which people --particularly children --might
insert objects and contact dangerous voltages.
Examples: Lamp hole, ventilation slots.
9. Inform the manufacturer of any oven found to have
emission in excess of 5 mW/cm2, Make repairs to
bring the unit into compliance at no cost to owner
and try to determine cause.
Instruct owner not to use oven until it has been
brought into compliance.
CENTRAL SERVICE CENTER
10. Service technicians should remove their watches
while repairing an MWO.
11. To avoid any possible radiation hazard, replace
parts in accordance with the wiring diagram. Also,
use only the exact replacements for the following
parts: Primary and secondary interlock switches,
interlock monitor switch.
12. If the fuse is blown by the Interlock Monitor Switch:
Replace all of the following at the same time: Pri-
mary, door sensing switch and power relay, as well
as the Interlock Monitor Switch. The correct adjust-
ment of these switches is described elsewhere in
this manual. Make sure that the fuse has the cor-
rect rating for the particular model being repaired.
13. Design Alteration Warning:
Use exact replacement parts only, i.e., only those
that are specified in the drawings and parts lists
of this manual. This is especially important for the
Interlock switches, described above.
Never alter or add to the mechanical or electri-
cal design of the MWO. Any design changes or
additions will void the manufacturer’s warranty.
Always unplug the unit’s AC power cord from the
AC power source before attempting to remove or
reinstall any component or assembly.
14. Never defeat any of the B+ voltage interlocks.
Do not apply AC power to the unit (or any of its
assemblies) unless all solid-state heat sinks are
correctly installed.
15. Some semiconductor (“solid state”) devices are
easily damaged by static electricity. Such compo-
nents are called Electrostatically Sensitive Devices
(ESDs). Examples include integrated circuits and
field-effect transistors.
Immediately before handling any semiconductor
components or assemblies, drain the electrostatic
charge from your body by touching a known earth
ground.
16. Always connect a test instrument’s ground lead to
the instrument chassis ground before connecting
the positive lead; always remove the instrument’s
ground lead last.
1-1 Safety precautions ( )

1-2 Special Servicing Precautions (Continued)
17. When checking the continuity of the witches or
transformer, always make sure that the power is
OFF, and one of the lead wires is disconnected.
18. Components that are critical for safety are
indicated in the circuit diagram by shading,
or .
19. Use replacement components that have the
same ratings, especially for flame resistance and
dielectric strength specifications. A replacement
part that does not have the same safety charac-
teristics as the original might create shock, fire or
other hazards.
1. High Voltage Warning
Do not attempt to measure any of the high volt-
ages --this includes the filament voltage of the
magnetron. High voltage is present during any
cook cycle. Before touching any components or
wiring, always unplug the oven and discharge the
high voltage capacitor (See Figure 1-1)
2. The high-voltage capacitor remains charged about
30 seconds after disconnection. Short the nega-
tive terminal of the high-voltage capacitor to to the
oven chassis. (Use a screwdriver.)
3. High voltage is maintained within specified limits
by close-tolerance, safety-related components
and adjustments. If the high voltage exceeds the
specified limits, check each of the special compo-
nents.

1. Isolate the diode from the circuit by disconnecting its leads.
2. With the ohm-meter set at the highest resistance scale, measure across the diode terminals. Reverse the
meter leads and read the resistance. A meter with 6V, 9V 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 KΩin the other direction.
5-4 High Voltage Capacitor
1. The relays are located on the PCB Ass’y. Isolate them from the main circuit by disconnecting the leads.
2. Operate the microwave oven with a water load in the oven. Set the power level set to high.
3. Check continuity between terminals of the relays after the start pad is pressed.
1. Check continuity of the capacitor with the meter set at the highest resistance scale.
2. Once the capacitor is charged, a normal capacitor shows continuity for a short time, and then indicates 9MΩ.
3. A shorted capacitor will show continuous continuity.
4. An open capacitor will show constant 9MΩ.
5. Resistance between each terminal and chassis should read infinite.
1. When mounting Primary switch and Interlock
Monitor switch to Latch Body, consult the figure.
2. No specific adjustment during installation of Pri-
mary switch and Monitor switch to the latch body is
necessary.
3. When mounting the Latch Body to the oven assem-
bly, adjust the Latch Body by moving it so that the
oven door will not have any play in it. Check for play
in the door by pulling the door assembly. Make sure
that the latch keys move smoothly after adjustment
is completed. Completely tighten the screws holding
the Latch Body to the oven assembly.
4. Reconnect to Monitor switch and check the continu-
ity of the monitor circuit and all latch switches again
by following the components test procedures.
5. Confirm that the gap between the switch housing
and the switch actuator is no more than 0.5mm
when door is closed.

The output power of the magnetron can be measured by performing a water temperature rise test.
Equipment needed :
* Two 1-liter cylindrical borosilicate glass vessel (Outside diameter 190 mm)
* One glass thermometer with mercury column
NOTE: Check line voltage under load. Low voltage will lower the magnetron output. Make all temperature
and time tests with accurate equipment.
1. Fill the one liter glass vessel with water.
2. Stir water in glass vessel with thermometer, and record glass vessel’s temperature (“T1”, 10±1°C).
3. After moving the water into another glass vessel, place it in the center of the cooking tray. Set the oven to
high power and operate for 49 seconds exactly. (3 seconds included as a holding time of magnetron oscilla-
tion:)
4. When heating is finished, stir the water again with the thermometer and measure the temperature (“T2”).
5. Subtract T1 from T2. This will give you the water temperature rise. ( ∆ T)
6. The output power is obtained by the following formula;
Output Power = 4.187 x 1000 x ∆ T + 0.88 x Mc x(T2 -T1) 49 : Heating Time (sec)
4.187 : Coefficient for Water
1000 : Water (cc)
∆T : Temperature Rise (T1-T2)
Mc : Cylindrical borosilicate glass weight
To : Room Temperature
46
7. Normal temperature rise for this model is 9°C to 11°C at ‘HIGH’.
NOTE 1: Variations or errors in the test procedure will cause a variance in the temperature rise.
Additional power test should be made if temperature rise is marginal.
NOTE 2: Output power in watts is computed by multiplying the temperature rise (step E) by a factor of 91
times the of centigrade temperature.

1. Remove the outer panel.
2. Pour 275±15cc of 20±5°C(68±9°F) water in a beaker
which is graduated to 600cc, and place the beaker in
the center of the oven.
3. Start the oven at the highest power level.
4. Set survey meter dual ranges to 2,450MHz.
5. Using the survey meter and spacer cone as described
above, measure near the opening 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 reading should be
less than 4mW/cm2 .
5-9 Procedure for Measurement of Microwave Energy Leakage
1) Pour 275±15cc of 20±5°C(68±9°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 probeperpendicular
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 a clockwise direction at a rate of 1 inch/sec. If the leakage testing of the cabi-
net 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 5cm to any metal. If it gets closer than 5cm,
erroneous readings may result.
5) Measured leakage must be less than 4mW/cm2 , after repair or adjustment.
Maximum allowable leakage is 5mW/cm2 .
4mW/cm2 is used to allow for measurement and meter accuracy
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 leakage 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.
5-12-1 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 4 mW/cm2 after determining that all parts are in good condition,
functioning properly and the identical parts are replaced as listed in this manual notify that fact to ;
CENTRAL SERVICE CENTER
5-12-2 At least once a year have the microwave energy survey meter checked for accuracy by its manufacturer.
