OPERATION
DESCRIPTION OF OPERATING SEQUENCE
The following is a complete description of component functions during oven operation.
OFF CONDITION
Closing the door activates both door interlock switches; lower latch switch and upper latch switch.
(In this condition, the monitor switch contacts are opened)
The stop switch is activated (contacis closed) by the lower
latch head, when the door is closed.
When oven is plugged in, the power supply voltage is added
to the control unit. But no components in the oven will operate, (Figure O-l)
-.
Note: When the door is opened by pushing the door open but-
ton, the oven lamp comes on.
1. The display will show flashing “88:88”.
To set any program or set the clock, you must first touch
the STOP/CLEAR pad. The display will clear, and 1:OO will
appear and count up every minute.
COOKING CONDITION
1. HIGH COOKING
Program desired cooking time and Variable Cooking Control by touching the NUMBER pads and the HIGH pad of the
Variable Cooking Control.
When the COOK (or START) pad is touched, the following
operations occur:
l-l.
1-2.
l-3.
1-4.
1-5.
1-6.
1-7.
1-8.
The power transformer, oven lamp, etc. are turned on.
(For details, refer to Figure O-2.)
The power supply voltage is added to the primary
winding of the power transformer and is converted
to about 3 volts A.C. output on the filament winding,
and approximately 2300 volts A.C on the high voltage winding.
About 3 volts A.C. output from the filament winding
heats the megnetron filament.
The 2300 volts A.C. is converted to approximately
4000 negative D.C. volts by the voltage doubler circuit consisting of a H.V. capacitor and rectifier and
sent to the magnetron cathode.
This causes the magnetron to oscillate and produce
the 2450 MHz cooking frequency.
This RF energy is channeled through the waveguide
into the cavity feed-box, and then into the cavity
where the food is placed to be cooked.
Upon completion of the cooking time, the power transformer, oven lamp, etc. are turned off, and the generation of microwave energy is stopped. The oven will
revert to the OFF condition.
When the door is opened during a cook cycle, the latch
switches, stop switch and monitor switch are activated with the following results. The circuits to the turntable motor, the cooling fan motor, and the high voltage
components are deenergized, the oven lamp remains
on, and the digital readout displays the time still remaining in the cook cycle when the door was opened.
l-9. The monitor switch is electrically monitoring the oper-
ation of the upper latch switch and is mechanically
associated with the door so that it will function in the
following sequence.
(1) When the door opens from a closed position, the
upper latch switch opens their contacts, and then
the monitor switch contacts close.
(2) When the door is closed from the open position,
the monitor switch contacts first open, and then
the contacts of the upper latch switch closes.
If the upper latch switch fails with its contacts closed when
the door is opened, the closing of the monitor switch contacts
will form a short circuit through the fuse, temp. fuse, upper
latch switch, causing the monitor fuse to blow.
2. MED HIGH, MED, MED LOW or LOW COOKING.
When the Variable Cooking is programed, power supply voltage is supplied to the power transformer intermittently
through the contacts of the cook relay which is operated
by the control unit within a 32 second time base.
The microwave power operation is as
follows:

beef, steak, whole chicken, chicken pieces and chops.
Each key has 3 defrost stages.
When the desired COMPU DEFROST number is selected and
the food weight is entered by using the number pad’s, the
oven will cook according to the special cooking sequence,

DESCRIPTION AND FUNCTION OF COMPONENTS
DOOR OPEN MECHANISM
The door can be opened by pushing the open button on the
control panel, refer to Figure D-l. When the open button is
pushed, the open plate on the open device pushes in the door
lever on the door, operating the latch head linkage. The lower
and upper latch heads are moved upward, and released from
the lower and upper latch hooks. Now, the door can be opened.

\ /
ASSEMBLY
OPkN
BUTTON
Figure D-1. Door Open Mechanism
LOWER AND UPPER LATCH SWITCHES
The lower latch switch is mounted in the lower latch hook and
the upper latch switch is mounted in the upper latch hook. They
are activated by the latch heads on the door. When the door
is opened, the switches interrupt the circuit to all components
except the oven lamps.
A cook cycle cannot take place until the door is firmly closed
thereby activating both interlock switches.
MONITOR SWITCH
The monitor switch, mounted on the upper latch hook, is activated (the contacts opened) by the upper latch head on the
door while the door is closed. This switch is intended to render
the oven inoperative by means of blowing the fuse when the
contacts of the upper latch switch failes to open when the door
is opened.
Functions:
1. When the door is opened, the monitor switch contacts close
(to ON condition) due to their being normally closed. At this
time the upper latch switch is in the OFF condition (contacts open) due to their being normally open contact
switches.
2. As the door goes to a closed position, the monitor switch
contacts are first opened and then the upper latch switch
contacts close. (On opening the door, each of these
switches operate inversely.)
3. If the door is opened and the upper latch switch contacts
fail to open, the fuse blows simultaneously with the closing of the monitor switch contacts.
CAUTION: BEFORE REPLACING A BLOWN FUSE, TEST
THE UPPER LATCH SWITCH SWITCH AND
MONITOR SWITCH FOR PROPER OPERATION.

MAGNETRON ASSEMBLY TEST
DISCHARGE THE HIGH VOLTAGE CAPACITOR BEFORE TOUCHING ANY OVEN
COMPONENTS OR WIRING.
To test for an open filament, isolate the magnetron from the high voltage circuit. A continuity check across
the magnetron filament leads should indicate less than 1 ohm.
To test for a shorted magnetron, connect the ohmmeter leads between the magnetron filament leads and
chassis ground. This test should indicate an infinite resistance.
If there is little or no resistance, the magne-
tron is grounded and must be replaced.
Power output of the magnetron can be measured by performing a water temperature rise test. This test
should only be used if above tests do not indicate a faulty magnetron and there is no defect in the following
components or wiring: rectifier, high voltage capacitor,
heater transformer and power transformer.
MICROWAVE OUTPUT POWER
Microwave output power from the magnetron can be measured by way of substitution, i.e. it can be measured by using water load how much it can be absorbed by the water load. To measure the microwave output
power in the microwave oven, the relation of calorie and watt is used.
When P (W) heating works for t (second), approximately P.t/4.2 calorie is generated. On the other hand,
if the temperature of the water with V (ml) rises AT (“C) during this microwave heating period, the calorie
of the water is V.AT.
The formular is as follows;
Pet
- =VaAT
4.2
P=
4.2 . : . AT (w)
.
Our condition for the water load is as follows;
Water load . . . . . 2000 ml
Heating time . . . . 120 seconds (2 minutes)
/I
Measuring method;
1. Put the water load of two (2) litres on the center of the oven shelf.
The water load should be arranged in two (2) Pyrex beakers, the size of which is one (1) litre, and be
placed at right and left, side by side, on the oven shelf.
2. Measure the temperature of water before heating and also after heating during two minutes by microwave, and calculate the temperature rise.
The temperature rise should be the average of temperature differences measured in each beaker.
3. The output power should be calculated as follows.
In case the measuring result is not satisfactory, execute the measurement several times and judge the
result from the synthetic point of view.
Microwave output power should be within f 15% of the nominal one.

Measuring condition;
As the microwave output is affected by several conditions, the measurement should be made carefully with
following attentions.
1. Initial temperature of salt water should be 20& 1 OC. (The salt water should be contained bon (1) percent
of salt.) Well and quickly stir the water and the temperature measurement should be done immediately
after heating.
2. The graduation of thermometer should be scaled by 0.1 OC at minimum and an accurate mercury thermometer is recommended.
3. Water container should be one (1) litre beaker made of Pyrex glass and its diameter approximately 12 cm,
4. Room temperature should be around 20°C.
5. Power supply voltage should be 240 volts.
B
POWER TRANSFORMER TEST
DISCHARGE THE HIGH VOLTAGE CAPACITOR BEFORE TOUCHING ANY OVEN
COMPONENTS OR WIRING.
Disconnect the primary input terminals and measure the resistance of the transformer with an ohmmeter.
Check for continuity of the coils with an ohmmeter. On the R x 1 scale, the resistance of the primary coil
should not be opened or should not be shorted, and the resistance of the high voltage coil should be approximately 84 ohms; the resistance of the filament coil should be less than 1 ohm.
(HIGH VOLTAGES ARE PRESENT TO HIGH VOLTAGE TERMINAL, SO DO NOT ATTEMPT TO
MEASURE THE FILAMENT AND HIGH VOLTAGE.)

RECTIFIER TEST
DISCHARGE THE HIGH VOLTAGE CAPACITOR BEFORE TOUCHING ANY OVEN
COMPONENTS OR WIRING.
Isolate the rectifier from the circuit. Using the highest ohm scale of the meter, read the resistance across
the terminals and observe, reverse the leads to the rectifier terminals and observe meter reading. If a short
is indicated in both directions, or if an infinite resistance is read in both directions, the rectifier is probably
defective and should be replaced.
D
HIGH VOLTAGE CAPACITOR TEST
DISCHARGE THE HIGH VOLTAGE CAPACITOR BEFORE TOUCHING ANY OVEN
COMPONENTS OR WIRING.
If the capacitor is open, no high voltage will be available to the magnetron. Disconnect input leads and check
for short or open between the terminals using an ohmmeter.
Checking with a high ohm scale, if the high voltage capacitor is normal, the meter will indicate continuity
for a short time and should indicate an open circuit once the capacitor is charged. If the above is not the
case, check the capacitor with the ohmmeter to see if it is short circuited between the terminals. If it is
short circuited, replace the capacitor.
E SWITCH TEST
Isolate the switch and check the connection by using the ohmmeter according to the table.
If improper operation is indicated, make the necessary switch adjustment or replacement.

Before performing this test, make sure that the Upper Latch Switch is operating properly referring to the
above Test Procedures:
Connect one ohmmeter lead to the fuse terminal, and the other lead to the power transformer terminal to
which the white wires from the wiring harness are connected.
When the door is open, the meter should indicate a closed circuit.
When the monitor switch lever of the upper latch hook is pushed by a screw driver through the upper latch
hole on the front plate of the oven cavity with the door opened (in this condition the plunger of the monitor
switch is pushed in), the meter should indicate an open circuit.
If improper operation is indicated, replaceqhe defective switch.

POWER SOURCE CIRCUIT
A power of AC 240V passes through the filter circuit (Ll) and
is applied to the primary winding of transformer (Tl).
The output voltage of the secondary winding of transformer
(Tl) is then full-wave rectified by the diode bridge (Dl -D4)
and smoothed by the electrolytic capacitor (C2) to become DC
voltage Vp (-32V).
Then the voltage Vp is delivered to the constant voltage circuit made up of transistor 0 1 and zener diodes ZD 1, ZD3 and
ZD4 where it is made into VP2 (-22V).
The voltage VP2 (-22V) results from the following equation:
VF2 (V) = VZDI + VZD3 + VZD4 - VBE (Q 1)
VDD (- 12V) is a voltage to be applied to the LSI and it de-
pends on the zener diode ZD3 and ZD4.
(VP1 -VP2) refers to a voltage to be applied to the heater of
the display tube and it is obtained from the following equation:
(vF1 *vF2) = (iI + i2) x Rf
In which, Rf is the heater’s resistor and il and i2 are load currents caused by the resistors R9 and R8 located in the heater.
Thus the heater’s voltage (VP1 -VF2) is specified at 3.5V.
Resistor R7 is provided between the collector and emitter of
the transistor 01 to have a part of the current running in 0 1
be by-passed: this results in a reduction of the current consumption of this transistor. Likewise, resistor R6 leads to a
reduction of the current consumption of zener diode ZD3 and
ZD4. C 1 and C5 are noise by-pass capacitors.

Just when the power switch is turned on, this circuit operates
to reset the LSI to its initial state.
With the power switch turned on, the voltage Vp starts to rise
up and other two voltages Vnn and VRES are made from this
voltage: Fig. T-5 shows the relation between these three
voltages.
When Vnn is high enough to keep the LSI in operation, if a voltage higher than V/H is applied to the RESET terminal of LSI,
the LSI is reset to its initial state.

While the unit is cooking, a “H” level signal is produced at D8
terminal of LSI and also a pulse signal at D9 terminal of LSI.
The pulse signal from D9 terminal is applied to the rectifier circuit made up of D82 and D83 where it is made into DC signal
to charge C81. With C81 charged up, Q4 and 03 turn on in
succession so that a current il is made to turn on the control
relay (RY-1).
The “H” level signal from D8 terminal is applied to Q2 which
is connected in series with Q3, and current i2 is made only

INDICATOR CIRCUIT
Method of Display
Indicator element is Fluorescent Display.
Basically, a Fluorescent Display is a triode having a cathode,
a grid and an anode. Usually, the cathode of Fluorescent Display is directly heated and the filament serves as cathode.
When a proper voltage is applied to the filament to heat it,
thermo-electrons emitted and, with positive voltage with
respect to filament being applied to the anode and grid elec-
trons hit against the anode to illuminate the fluorescent body.
If the anode or grid voltage is zero or negative against the fila-
ment, thermo-electrons can not reach the anode, hence the
fluorescent body is not luminescent.
In this model, the Fluorescent Display 6-digits, 1 l-segments
are used for displaying figures.
The Fluorescent Display employs the dynamic drive method,
when the high level of anode signal and grid signal agree, the
corresponding segment displays.

SERVICING
1. Precautions for Handling Electronic Components
This unit uses PMOS LSI in the integral part of the circuits.
When handling these parts, the following precautions should
be strictly followed.
PMOS LSI have extremely high impedance at its input and
output terminals. For this reason, it is easily influenced by
the surrounding high voltage power source, static electricity charged in clothes, etc, and sometimes it is not fully protected by the built-in protection circuit.
In order to protect PMOS LSI.
1) When storing and transporting, thoroughly wrap them
in aluminum foil.
Also wrap PW boards containing them in aluminium foil.
2) When soldering, ground the technician as shown in the
figure and use grounded soldering iron and work table.

3. Servicing of Touch Control Panel
We describe the procedures to permit servicing the touch
control panel of the microwave oven and the cautions you
must consider when doing it.
To carry out the servicing, power supply to the touch control panel is available either from the power line of the oven
or from an external power source.
(I) In the case of servicing the touch control panel with
power supply from the oven:
CAUTION;
IN THIS CASE, THE HIGH TENSION TRANSFORMER
OF THE MICROWAVE OVEN IS STILL ALIVE TO
GIVE YOU DANGER DURING THE SERVICING.
[Therefore, when checking the performance of the touch
control panel, put the outer cabinet on the oven proper
to keep you from touching the high tension transformer, or unplug the primary terminal (connector) of the high
tension transformer to turn it off; and the end of such
connector shall be insulated with an insulating tape. After servicing, be sure to replace the leads to their origi-
nal located.]
A. On some models, the power supply cord between the
touch control panel and the oven is so short that they
can’t be separated from each other.
For those models, therefore, check and repair all the con-
trols (with the sensor-related ones included) of the touch
control panel while keeping it in contact with the oven.
B. For some models, the power supply cord between the
touch control panel and the oven is long enough that they
may be separated from each other. For those models,
therefore, it is allowed to check and repair the controls
of the touch control panel while keeping it apart from
the oven; in this case it is needed to short both ends of
the stop switch (on PWB) of the touch control panel with
a lead or the like, which brings about such an operational
state is equivalent to that with the oven door being
closed.
With the touch control panel apart from the oven,
however, it is not possible to check the sensorrelated
controls of the touch control panel.
(2) In the case of servicing the touch control panel with
power supply from an external power source:
Disconnect the touch control panel completely from the
oven, and short both ends of the stop switch (on PWB)
of the touch control panel, which brings about such an
operational state that is equivalent to that with the oven
door being closed. And connect an external power
source to the power input terminal of the touch control
panel, and then it is allowed to check and repair the controls of the touch control panel.
Servicing Tools
Tools required when servicing the touch control panel assembly.
1) Soldering: 30W
(To prevent leaking current, it is recommended to use
a soldering iron with grounding terminal.)
2) Oscilloscope: Single beam, frequency range: DC -
IOMHz type or more advanced model
3) Others: Other tools
Other Precautions
When tur?ing on the power source of the control unit,
remove the aluminum foil applied for preventing static
electricity.
Connect the connectors of the indicator and key units
to the control unit taking care that the lead wires are not
twisted.
After aluminum foil is removed, take extra care that abnormal voltage due to static electricity etc. is not applied
to the input or output terminals.
Attach connectors, electrolytic capacitors, etc. to PW
board, taking care that all connections are tight.
Be sure to use specified components where high precision is required.

not operate properly due to a mis-adjustment, the following
adjustment should be made.
1. Loosen the single (1) screw holding the upper latch hook
to the oven cavity front flange and the single (1) screw holding the lower latch hook to the same flange.
2. With the door closed, adjust the lower latch hook by moving it back and forward and then adjust the upper latch hook
by moving it back and forward, or up and down.
In and out play of the door allowed by the upper and lower
latch hooks should be less than 0.5mm.
The vertical position of the upper latch hook should be
placed where the upper latch switch and monitor switch
have activated with the door closed.
Vertical adjustment of the lower latch hook is not possible.
3. Secure the screws with washers firmly.
4. Now, make sure of the upper latch switch operation. If the
upper latch switch has not activated with the door closed,
loosen the single (1) screw holding the upper latch hook to
the oven cavity front flange and adjust the upper latch hook
position.
After the adjustment, make sure of the following points:
1. The in and out play of the door remains less than 0.5mm
at latched position. First check the upper latch hook position, pushing and pulling the upper portion of door toward
the oven face. Then check the lower latch hook position,
pushing and pulling the lower portion of door toward the
oven face. Both results (plays of the door) should be less
than 0.5mm.
2. The upper and lower latch switches interrupt the circuit before the door can be opened.
3. The monitor switch contacts close when the door is opened.
4. Re-install the outer case and check for microwave leakage
around the door with an approved microwave survey meter.

-.
Note: After any service to the door:
(A) Make sure that the latch switches are operating properly.
(Refer to chapter
“Test Procedure”.)
(B) An approved microwave survey meter should be used to
assure compliance with proper microwave radiation emis-
sion limitation standards.
DOOR ADJUSTMENT
The door is adjusted by keeping the screws of each hinge loose.
After the adjustment, make sure of the following:
1. The door latch heads smoothly catch, the latch hooks
through the latch holes, and also the latch heads go through
the center of the latch holes.
2. Deviation of the door alignment from the horizontal line of
the cavity face plate is to be less than 1 .Omm.
3. The door is positioned with its face depressed toward the
cavity face plate.
4. Re-install the outer case and check for microwave leakage
around the door with and approved microwave survey
meter. (Refer to Microwave Measurement Procedure.)
Note: The door on a microwave oven is designed to act as an
electronic seal preventing the leakage of microwave
energy from the oven cavity during the cook cycle.
This function does not require that the door be airtight,
moisture (condensation)-tight or light-tight.
Therefore, the occasional appearance of moisture, light
or the sensing of gentle warm air movement around the
oven door is not abnormal and do not of themselves,
indicate a leakage of microwave energy from the oven
cavity. If such were the case, your oven could not be
equipped with a vent, the very purpose of which is to
exhaust the vapor-laden air from the oven cavity.

MICROWAVE MEASUREMENT
After the adjustment of door interlock switches and door is
completed individually or collectively, the following leakage test
must be performed with a survey instrument and it must be
confirmed that the result meets the requirements of the per-
formance standard for microwave oven.
REQUIREMENT
The safety switch must prevent microwave radiation emission
in excess of 5mW/cm2 at any point 5cm or more from external surface of the oven.
PREPARATION FOR THE TESTING:
Before beginning the actual test for leakage, proceed as
follows;
1. Make sure that the test instrument is operating normally as
specified in its instruction booklet.
Important:
Survey instruments that comply with the requirement for
instrumentation as prescribed by the performance standard
for microwave ovens must be used for testing.

SIMPSON 380M
Place the turntable tray into the oven cavity.
Place the load of 275k 15ml of water initially at 20& 5OC
in the centre of the oven tray. The water container should
be a low form of 600ml beaker with inside diameter of approx. 8.5cm and made of an electrically nonconductive
material such as glass or plastic.
The placing of this standard load in the oven is important
not only to protect the oven, but also to insure that any leakage is measured accurately.
Close the door and turn the oven ON with the timer set for
several minutes. If the water begins to boil before the survey is completed, replace it with 275ml of the cool water.
Move the probe slowly (not faster than 2.5cm/sec.) along
the gap.
The microwave radiation emission should be measured at
anv ooint of 5cm or more from the external surface the oven.
