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

1. Precaution

1-1 Safety precautions ( )

Samsung Electronics 1-1

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
contact the manufacturer and the center for
devices and radiological health immediatly.

4. Notify the Central Service Center if the
microwave leakage exceeds 5 mW/cm

2

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 emmission 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: Primary, door sensing switch
and power relay, as well as the Interlock
Monitor Switch. The correct adjustment of
these switches is described elsewhere in this
manual. Make sure that the fuse has the
correct 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
electrical design of the MWO. Any design
changes or additions will void the
manufacturer's warranty.10.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
components 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.

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.

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 characteristics as the original
might create shock, fire or other hazards.

1. High Voltage Warning
Do not attempt to measure any of the high
voltages--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 negative terminal of the high-voltage
capacitor 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 components.

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 9MW.

3. A shorted capacitor will show continuous continuity.

4. An open capacitor will show constant 9MW.

5. Resistance between each terminal and chassis should read infinite.

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 KW in

the other direction.

1. When mounting Primary switch and Interlock
Monitor switch to Latch Body, consult the
figure.

2. No specific adjustment during installation of
Primary switch and Monitor switch to the latch
body is necessary.

3. When mounting the Latch Body to the oven
assembly, 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
continuity 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.

5-7 Microwave Heat Distribution - Heat Evenness

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 the water temperature in the glass vessel("T1", 10±1ûC).

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 52 seconds exactly. (3 seconds included as a holding time of magnetron oscillation:)

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. (DT)

6. The output power is obtained by the following formula;

The microwave heat distribution can be checked indirectly by measuring the water temperature rise at
certain positions in the oven:

1. Prepare five beakers made of 'Pyrex', having 100 milliliters capacity each.

2. Measure exactly 100milliliters off water load with a measuring cylinder, and pour into each beaker.

3. Measure the temperature of each water load. (Readings shall be taken to the first place of decimals.)

4. Put each beaker in place on the cooking tray as illustrated in figure below. Start heating.

5. After heating for 2 minutes, measure the water temperature in each beaker.

6. Microwave heat distribution rate can be calculated as follows:

Minimum

Temperature Rise

Heat Distribution = X 100(%)

Maximum

Temperature Rise

The result should exceed 65%.

5-11-2 At least once a year have the microwave energy survey meter checked for accuracy by its

manufacturer.

1. Remove the outer panel.

2. Pour 275±15cc of 20±5ûC(68±9ûF) 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 arnear 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 neading
should be less than 5mW/cm2.

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.

1) Pour 275±15cc of 20±5ûC(68±9ûF) 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 a 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
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/cm2is used to allow for measurement and meter accuracy
