OPERATION
NORMAL COOKING SEQUENCE
To start cooking;
Microwave
1, Turn the main switch ON.
(Continental Europe and South African Models only.) 2. Set the browner position control knob fully to the left.
Now the browner heater is placed at the highest
position.
3. Place the food to be cooked in the oven and close the
door firmly.
4. Set the variable cooking mode selector for a desired
position.
5. Set the microwave timer for a desired cooking time.
The oven light will come on and the fan motor will
rotate immediatedly.
6. Depress the cook button. The microwave indicator
light will glow to indicate that the oven is in the
microwave cooking cycle, and the turntable motor and
vari-motor will operate.
7. At the end of the microwave cooking cycle (microwave
timer returns to “O”), the indicator light will go out
and the timer bell will ring once. The oven will stop
supplying the microwave energy.
Browing
1. Turn the main switch ON.
(Countinental Europe and South African Models only.)
2. Set the browner position control knob to fully left,
and open the door.
3. Place the food to be heated in the oven and close the
door firmly.
4. Select the browner control knob for a desired position.
5, Be sure the microwave timer is at “O” position and set
the browner timer for a desired cooking time. At this
time the oven light will come on and the fan motor will
rotate immediately.
6. Depress the cook button, The browner indicator light
will glow to indicate that the oven is in the browning
cycle and turntable motor will operate.
7. At the end of the browning cycle, the timer signal bell
will ring once and the heater will turn off.
8. To open the door, the browner position control knob
has to be placed fully to the left.
Notes: 1. The door cannot be opened without setting
the browner heater at the highest position.
2. If the oven door is opened during the cooking
operation, the oven will go out of the cook
cycle and the timer will stop. This is done so
the exact cooking time remains on the timer.
To restore cooking operation, the door must be
closed and cook button must be depressed.
3. When both the microwave timer and the
browner timer are set, the oven will supply.
the microwave energy first. In this case the
browning heater will turn on when the micro-
wave timer returns to “0”.
4, One or both timers can be set;
A) If microwave cooking is desired, set only
the microwave timer and depress the cook
button.
B) If microwave cooking is desired first and
browning immediately after, set both timers
for the desired times.
MICROWAVE COOKING ALWAYS
TAKES PLACE FIRST WHEN BOTH
TIMERS ARE SET. If browning is desired first and then micro-
wave cooking, set only browner timer. The
microwave timer should be set after brown-
ing cycle is completed.

DESCRIPTION OF OPERATING SEQUENCE
The following is a complete description of component
functions during the three stages of oven operation.
Note: The following operations are refer to the Con-
tinental Europe Model and the others are quite
similar in each model.
OFF CONDITION
With the main switch turned on, the timer at “0” position
and the door closed, no component in the oven will
operate. But the oven light will turn on when the door is
opened.
IDLE CONDITION
Closing the door activates both interlock switches; primary
interlock (upper latch) switch and secondary interlock
(lower latch) switch.
Selecting a cooking time closes the microwave or/and
browner timer contacts leading to the oven light and fan
motor therefore the oven light turn on and the fan motor
rotates.
COOKING CONDITION MICROWAVE COOKING CONDITION The followings are the complete microwave cooking operation; (Figure 1.) A. Full Power Condition
When the variable cooking mode selector is set fully right (“Full Power” position) and the cook switch is depressed, the following operation occurs; .
A-1.The tumtable motor, microwave timer motor, microwave indicator light and vari-motor are energized.
A-2.The surge limiting relay is energized through. the vari-switch.
A-3.The 220 volis A.C. is supplied to a primary winding of the power transformer through the vari-switch and surge limiting relay contacts (15)- (16).
' A-4.The power transformer converts 3.2 volts A.C. output on the filament winding and approximately 2400 volts A.C. on the high voltage winding.
A-5.The 3.2 volts A.C. output from filament winding heats the magnetron filament. |
A-6.The 2400 volts A.C. output from the secondary winding is sent to a voltage doubler circuit consisting of a high voltage capacitor and a silicon rectifier. The 2400 volts A.C. is converted to approximately 4000 negative D.C. voltage (peak to peak) by the voltage doubler circuit and sent to the magnetron assembly.
A-7.The negative 4000 volts D.C. is applied to the cathode of the magnetron tube. This causes it to oscillate and produce a 2450 MHz cooking fre- quency.
A-8.The RF energy produced by the magnetron tube is channeled through a waveguide into the cavity feedbox, and then into the cavity where the food is placed to be heated.
A-9.Upon completion of the selected cooking time, the timer bell rings once and the timer switch is deactivated. The oven is reverted to the off condition.
B-
B-2. e
B-3.
B-4.
Defrost, Simmer and Roast Condition When the cook switch is depressed and the variable cooking mode selector is set to “DEFROST”, “SIMMER” or “ROAST” position, the following operation occurs; |
- Above A-1, A-2 and A-3 operations occur. The vari-motor rotates at (2) r.p.m. In case the mode selector is set at “DEFROST”, the 220 volts A.C. is supplied intermittently to the surge limiting relay through the vari-switch and the power transformer through the vari-switch and surge limiting relay contacts (15)-(16). The vari-switch is operated, at a 9 seconds ON and 21 seconds OFF repetition rate, by means of the cam provided on the vari-motor shaft. The repetition rate for others are as follows;
SIMMER: 15 seconds ON, 15 seconds OFF ROAST: 21 seconds ON, 9 seconds OFF
The 3.2 and 2400 volts A.C. outputs are converted while the 220 volts A.C. is supplied to the power transformer.
Then above A-5, A-6, A-7, A-8 and A-9 operations occur.
BROWNING CONDITION When the browner timer is set and the cook switch is
depressed, the following operation occurs; 2-1.
2-2.
2-3.
Note:
The turntable motor, browner timer motor and
browner indicator light are energized. The 220 volts A.C. is supplied to the browning element.
Upon completion of the selected cooking time, the timer bell rings once as the timer switch is deactivated and the oven reverts to the off condi- tion.
When both microwave and browner timers are set,
microwave energy is produced first. In this case,
the browning element will be activated when the
microwave timer returns to “0” position.

TEST PROCEDURES
COMPONENT TEST
MAGNETRON ASSEMBLY
HIGH VOLTAGES ARE PRESENT DURING THE COOK CYCLE, SO EXTREME CAUTION SHOULD BE
OBSERVED.
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 magnetron is grounded
and must be replaced.
Power output of the magnetron can be measured by means of a water temperature rise test. This test should only be
used if the preceding test does not indicate a faulty magnetron and there is no defect on the following components
or wiring: silicon rectifier, high voltage capacitor and power transformer.
Refer to Microwave Output Power Measurement in GENERAL SERVICE MANUAL on pages 6 and 7.
POWER TRANSFORMER TEST
DISCHARGE THE HIGH VOLTAGE CAPACITOR BEFORE TOUCHING ANY OVEN COMPONENTS OR
WIRING
Disconnect the primary input terminals and measure the resistance with an ohmmeter. Check for the continuity
of the coils with an ohmmeter. On the RX1 scale, the resistance of the primary coil shouJd be approximately 1 ohm
and the resistance of high voltage coil should be approximately 77 ohms, and the resistance of filament coil should
be approximately 1 ohm. With 220/240 volts A.C. applied to the primary winding, the voltage across the filament
winding should be approximately 3.2 volts A.C. (HIGH VOLTAGES ARE PRESENT TO HIGH VOLTAGE TER-
MINAL, SO EXTREME CAUTION SHOULD BE OBSERVED.)

TEST PROCEDURES (CONT'D)
PROCEDURE NUMBER COMPONENT TEST
PRIMARY INTERLOCK SWITCH (UPPER LATCH SWITCH) TEST
The primary interlock switch can be checked with an ohmmeter. Isolate the switch and then connect the meter leads to the common (COM.) and normally open (N.O.) terminals of the switch. The meter should indicate an open circuit with the door opened and the closed circuit with the door closed. In case improper operation is indicated, make the necessary switch adjustment or replace the defective switch. See adjustment procedure on page 22,
SECONDARY INTERLOCK SWITCH (LOWER LATCH SWITCH) TEST eR RAE OEE) I EOL Isolate the switch and connect the ohmmeter leads to the common (COM.) and normally open (N.Q.) terminals of the switch. The meter should indicate an Open circuit with the door opened and a closed circuit with the door closed. When the meter jJeads are connected to the common (COM.) and normally closed (N.C.) terminals of the switch, it should indicate a closed circuit with the door opened and an open circuit with the door closed. In case improper operation is indicated, make the necessary switch adjustment or replace the defective switch. See adjustment procedure on page 22.
THERMO CUT-OUT TEST
A continuity check across the thermo cut-out should indicate a closed circuit unless the temperature of the thermo cut-out reaches approximately 104°C. The thermo cut-out resets automatically at approximately 79°C. An open thermo cut-out indicates over heating of the magnetron assembly (or oven cavity). Check for testricted air flow to the magnetron {or oven cavity) through the opening in the chassis, especially the cooling duct and air intake.
VARI-SWITCH TEST
The vari-switch is activated by the cam lever and cam. When the variable cooking mode selector is set at “FULL POWER” position, the cam is placed far away from the cam lever. In this condition, the vari-switch is turned ON by a spting action of the cam lever.
The vari-switch can be checked with an ohmmeter.
When the meter leads are connected to the common (COM.) and normally open (N.O.) terminals of the switch, it Should indicated a closed circuit with the cam lever released and an open circuit with the cam lever depressed. If improper operation is indicated, make the necessary adjustment on the mode selector assembly or replace the defective switch.
VARI-MOTOR TEST
The vari-motor rotates at two (2) r.p.m.
Check if 220/240 volts is present between the motor terminals. If voltage is present, but the motor does not turn, Teplace the motor. If no voltage is present, check for loose or broken wire connections.
BROWNING ELEMENT TEST
a. Disconnect heater leads and measure the resistance with an ohmmeter. On the RX1 scale, the resistance between the heater leads should be approximately 37 ohms at Continental Europe and South African Models, and approximately 44 ohms at Australian and U.K. Models.
b. Disconnect heater leads and measure the insulation resistance with S00V-100M2 insulation resistance meter. The insulation resistance between heater lead und cavity should be more than 0.4MQ,
