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.
1-1 Safety precautions (/\ )
1.
Da
10.
11.
All repairs should be done in accordance
with the procedures described in this manual.
Microwave emission check should be
performed to prior to servicing if the oven is
operative.
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 immediately.
Notify the Central Service Center if the
microwave leakage exceeds 5 mW/cm’.
Check all grounds.
Do not power the MWO from a "2-prong"
AC cord. Be sure that ail of the built-in
protective devices are replaced. Restore any
missing protective shields.
When reinstalling the chassis and its
assemblies, be sure to restore all protective
devices, including: nonmetallic control
knobs and compartment covers.
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.
Inform the manufacturer of any oven found
to have emission in excess of 5 mW/cm’ ,
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.
Service technicians should remove their
watches while repairing an MWO
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.
. 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:
14.
15.
16.
17.
18.
19.
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. Always unplug
the unit’s AC power cord from the AC
power source before attempting to
remove or reinstall any component or
assembly.
Always unplug the unit’s AC power cord
from the AC power source before
attempting to remove or reinstall any
component or assembly.
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.
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.
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
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.
Components that are critical for safety are
indicated in the circuit diagram by
shading, A\ or A\ -
. Use replacement componenis 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.

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 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.
PRECAUTION
Negative
Terminal
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.
DO NOT measure the voitage in the high voltage
circuit including filament voltage of magnetron.
Note : Touch chassis side first then short
to the high voltage capacitor
terminal by using a screwdriver.
PRECAUTION
Never touch any circuit wiring with your hand nor
with an insulated tool during operation.
PRECAUTION
Servicemen should remove their watches
whenever working close to or replacing the
magnetron.
