5 DESCRIPTION OF

OPERATING SEQUENCE

5.1. Variable power cooking

control

HIGH VOLTAGE INVERTER POWER SUPPLY (U) controls

output power by the signal from Digital programmer Circuit

(DPC). Power relay 2 stays on while 1000W to 300W selection

but the inverter drive signal to control it‘s output power 150 W

and 100 W will be ON-OFF controlled.

NOTE: The ON/OFF time ratio does not correspond with

the percentage of microwave power since approximately 2

seconds are required for heating of magnetron filament.

5.2. Defrost

When auto weight defrost is selected and the start Pad is

tapped:

1. The digital programmer circuit determines the power level

and cooking time to complete cooking and indicates the

operating stage in the display window. Table shows the

corresponding cooking time for respective serving by

categories.

2. When cooking time in the display window has elapsed, the

oven turns off automatically by a control signal from the digital

programmer circuit.

5.3. Convection Grill Cooking

Control

The digital programmer circuit controls the ON-OFF time of the

heater in order to control oven cavity temperature.

1. After the start pad is tapped with the desired Bake-Broil

program set, an high level signal comes out Micro-Computer

circuit and is applied to gate of triacs, D222 and D223.

2. When triacs turns on, power source voltage is applied the

heater and the heater turns on.

3. When the oven temperature reaches the set temperature,

the digital programmer circuit senses the temperature through

oven temp sensor and stops supplying high level signal to the

triacs and the heater turns off.

4. After the heater turns off, the oven temperature will continue

increasing a while and then decrease as shown in Figure.

When the oven temperature drops below the set temperature,

the digital programmer circuit senses the signal and starts

supplying an high level signal to the trialc again.

5.4. Combination cooking control

Combination cooking is accomplished by microwave and

convection cooking being done alternately during one

combination cooking cycle. One combination cooking cycle is

22 seconds.

1. During combination cooking, the digital programmer circuits

ON-OFF time of both heater and magnetron shown in Figure.

NOTE 1: Note that the heater may not be on during a heater

on period if the preporgrammed oven temperture has been

reached. This is due to the fact that the oven is keeping the

preporgrammed oven temperature constant, so of course

5.5. Sensor reheating

The temperature of the foods being heated is detected by an

infrared (IR) sensor and you do not have to set the temperature

or time.

5.5.1. How to read temperature by IR

sensor

IR sensor can read food temperature without touching, IR rays

emitted from food. IR sensor to generate temperature related

electric signal output and micro-computer to convert actual

temperature.

5.5.2. Operation

IR sensor is mounted top back of oven cavity through the hole.

It scans all over cooking shelf. IR sensor has 8 eyes and can be

the heater will only be on when it is needed and off when

it is not needed.

NOTE 2: As for temperatures of combination cooking for

convection, the temperatures by each program are

preporgrammed in the microprocessor as shown in Figure.

read oven shelf front to back at the time. Then IR sensor is

design to scan right to left to cover all over shelf. (19 points)

6.1. Water supply

As showing in figure, water in water tank will be pumped up and

supply to the steam generation heater located inside back

bottom of oven cavity.

6.2. Operation

When pushing start bottom, oven preheat will start and then

water supply begins. It will take about 2 minutes for pre-

heating. When preheat is completed, it will turn into actual

cooking process. During heating, temperature sensor located

on steam sensor monitoring steam heater temperature and

when it exceeds 95C, then additional water to supply to

maintain moisture/steam within oven cavity.

6 STEAM FUNCTION

(STEAM & MICRO POWER AND Reheat with STEAM.)

NN-J993

Unlike many other appliances, the microwave oven is high-

voltage, high-current equipment. Though it is free from danger

in ordinary use, extreme care should be taken during repair.

7.1. Check the grounding

Do not operate on a 2-wire extension cord. The microwave

oven is designed to be used when grounded. It is imperative,

therefore, to make sure it is grounded properly before

beginning repair work.

7.2. Inverter Warnings (NEW H.V.)

7.3. When parts must be replaced,

remove the power plug from

the outlet.

7.4. When the 10A/18A 250V fuse

is blown due to the operation

of short switch:

1. This is mandatory. Refer to “Adjustments and Measurement”

for these switches.

2. When replacing the fuse, confirm that it has the appropriate

rating for these models.

3. When replacing faulty switches, be sure mounting tabs are

not bent, broken or therwise deficient in their ability to hold the

switches.

7.5. Avoid inserting nails, wire, etc.

through any holes in the unit

during operation.

Never insert a wire, nail or any other metal object through the

lamp holes on the cavity or any other holes gaps, because such

objects may work as an antenna and cause microwave

leakage.

7.6. Confirm after repair

1. After repair or replacement of parts, make sure that the

screws of the oven, etc. are neither loose nor misssing.

microwaves might leak if screws are not properly tightened.

2. Make sure that all electrical connections are tight before

inserting the plug into the wall outlet.
