CHAPTER 2. WARNING TO SERVICE PERSONNEL

The ovens contain circuitry capable of producing very high voltage and current, contact with following parts may result in a severe, possibly fatal,
electrical shock.

(Example)

Inverter unit, Magnetron, High Voltage Harness etc..

Read the Service Manual carefully and follow all instructions.

[1] Before Servicing

1. Disconnect the power supply cord, and then remove the outer case and the back plate assembly.

2. Open the door and block it open.

3. Wait for 60 seconds to discharge the high voltage capacitors of the inverter unit.

4. Disconnect the high voltage wire from the magnetron terminal with insulated pliers.

5. Make the terminal (metal part) of the high voltage wire contact to the magnetron body with insulated pliers.

6. Now, the capacitors of the inverter unit are discharged.

7. Reconnect the high voltage wire to the magnetron terminal after discharging.

WARNING: Use the pliers that the portions of their handles are insulated completely to avoid an electric shock.

WARNING: RISK OF ELECTRIC SHOCK. DISCHARGE THE HIGH-VOLTAGE CAPACITOR BEFORE SERVICING.

The high-voltage capacitor remains charged about 60 seconds after the oven has been switched off. Wait for 60 seconds.

Whenever troubleshooting is performed the power supply must be disconnected. It may, in some cases, be necessary to connect the power supply
after the outer case has been removed, in this event,

1. Disconnect the power supply cord, and then remove the outer case and the back plate assembly.

2. Open the door and block it open.

3. Wait for 60 seconds to discharge the high voltage capacitors of the inverter unit.

4. Disconnect the high voltage wire from the magnetron terminal with insulated pliers.

5. Make the terminal (metal part) of the high voltage wire contact to the magnetron body with insulated pliers.

6. Now, the capacitors of the inverter unit are discharged.

2. Reinstall the outer case (cabinet) and the back plate assembly.

3. Reconnect the power supply cord after the outer case and the back plate assembly are installed.

4. Run the oven and check all functions.

Super-Steam ovens should not be run empty. To test for the presence of microwave energy within a cavity, place a cup of cold water on the ceramic
oven floor, close the door and set the power to 100% and set the microwave timer for two (2) minutes. When the two minutes has elapsed (timer at
zero) carefully check that the water is now hot. If the water remains cold carry out Before Servicing procedure and re-examine the connections to the
component being tested.

When all service work is completed and the oven is fully assembled, the microwave power output should be checked and microwave leakage test
should be carried out.

[4] Before replacing the Printed Wiring Board

Some normal boards are found in board units that have been returned due to oven failure. So, most of board replacements may arise from poor har­ness connection. Accordingly, before replacing any board that was judged to require its replacement, use the following procedure to re-check that the
connection terminal of a connector has been properly inserted:

1. When the connectors have been incorrectly inserted to the control unit.

2. When latch switch adjustment is incorrect

When latch switch adjustment is incorrect, symptoms such as no heating, no heating start, no activation even with start button pressed, etc. will occur.

CHAPTER 3. PRECAUTIONS FOR USING LEAD-FREE SOLDER

Employing lead-free solder

The “Main PWB” of this model employs lead-free solder. This is indicated by the “LF” symbol printed on the PWB and in the service manual. The suffix
letter indicates the alloy type of the solder.

Example:

Using lead-free wire solder

When repairing a PWB with the “LF” symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may result in cold soldered
joints and damage to printed patterns.)

As the melting point of lead-free solder is approximately 40°C higher than tin/lead alloy solder, it is recommend that a dedicated bit is used, and that
the iron temperature is adjusted accordingly.

Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer wet ability, (flow), to prevent damage to the land of the PWB, extreme
care should be taken not to leave the bit in contact with the PWB for an extended period of time. Remove the bit as soon as a good flow is achieved.
The high content of tin in lead free solder will cause premature corrosion of the bit. To reduce wear on the bit, reduce the temperature or turn off the
iron when it is not required.

Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their characteristics, making good soldering
more difficult. It will be necessary to clean and replace bits more often when using lead-free solder. To reduce bit wear, care should be taken to clean
the bit thoroughly after each use.

1. When the oven is plugged in with the door closed, the line voltage is supplied to the noise filter. And the display shows nothing.

2. When the door is opened with plugged in, the contacts (COM-NC) of the secondary interlock switch is closed. And the line voltage is supplied to
the T/C transformer and the control unit. Then the contacts of the relay RY-8 are closed and the oven lamp is turned on. And the contacts of the
relay RY-11 are closed. The display shows “ENERGY SAVE MODE”.

3. When the door is closed, the contacts (COM-NC) of the secondary interlock switch are opened. Because the contacts of the relay RY-11 have
been closed, the line voltage is kept supplying to the T/C transformer and the control unit. But the contacts of the relay RY-8 are opened and the
oven lamp is turned off.

NOTE: Energy save mode

1) If the oven has not been used for 3 minutes or more, the contacts of the relay RY-11 will be opened and the control unit will be not ener­gized. Open and close the door, the control unit will resume.

2) If the display shows different messages from ENERGY SAVE MODE, this energy save mode does not work.

CHAPTER 6. TEST PROCEDURE

[1] MAGNETRON (MG) TEST

NEVER TOUCH ANY PART IN THE CIRCUIT WITH YOUR HAND OR AN INSULATED TOOL WHILE THE OVEN IS IN OPERATION.

CARRY OUT 3D

CHECKS.

Isolate the magnetron from the high voltage circuit by removing all leads connected to the filament terminal.

To test for an open circuit filament use an ohmmeter to make a continuity test between the magnetron filament terminals, the meter should show a
reading of less than 1 ohm.

To test for a short circuit filament to anode condition, connect ohmmeter between one of the filament terminals and the case of the magnetron
(ground). This test should be indicated an infinite resistance. If a low or zero resistance reading is obtained then the magnetron should be replaced.

MICROWAVE OUTPUT POWER (1 litre water load)

The following test procedure should be carried out with the microwave oven in a fully assembled condition (outer case fitted). Microwave output power
from the magnetron can be measured by IEC test procedure, 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 (sec-

ond), approximately P x t/4.187 calorie is generated. On the other hand, if the temperature of the water with V(ml) rises T (°C) during this microwave

heating period, the calorie of the water is v x T.

Measuring condition:

1) Container

The water container must be a cylindrical borosilicate glass vessel having a maximum material thickness of 3 mm and an outside diameter of
approximately 190 mm.

2) Temperature of the oven and vessel

The oven and the empty vessel are at ambient temperature prior to the start of the test.

3) Temperature of the water

The initial temperature of the water is (10±1)°C

4) Select the initial and final water temperature so that the maximum difference between the final water temperature and the ambient temperature is
5°C.

5) Select stirring devices and measuring instruments in order to minimize addition or removal of heat.

6) The graduation of the thermometer must be scaled by 0.1°C at minimum and an accurate thermometer.

7) The water load must be (1000±5) g.

8) “t” is measured while the microwave generator is operating at full power. Magnetron filament heat-up time is not included.

NOTE: The operation time of the microwave oven is “t + 3" sec. 3 sec. is magnetron filament heat-up time.

Measuring method:

1) 1.Measure the initial temperature of the water before the water is added to the vessel.

(Example: The initial temperature T1 = 11°C)

2) Add the 1 litre water to the vessel.

3) Place the load on the centre of the shelf.

4) Operate the microwave oven at 100% for the temperature of the water rises by a value T of 10°C.

5) Stir the water to equalize temperature throughout the vessel.

6) Measure the final water temperature. (Example: The final temperature T2 = 21°C)

7) Calculate the microwave power output P

in watts from above formula.

JUDGEMENT: The measured output power should be at least ± 15% of the rated output power.

CAUTION: 1°C CORRESPONDS TO 80 WATTS. REPEAT MEASUREMENT IF THE POWER IS INSUFFICIENT.

The formula is as follows;

P x t / 4.187 = V x T+ 0.55 x mc (T2-T0)/4.187 P (W) = 4.187 x V x T / t + 0.55 x mc (T2-T0)/t
Our condition for water load is as follows:

Room temperature (T0) ......................... around 20°C Power supply ........................... VoltageRated voltage

Water load .........................................................1000 g Initial temperature (T1) .................................... 10±1°C

Heating time ..................................................... 52 sec. Mass of container (mc) ...................................... 330 g

T2 .................................................... Final Temperature T = T2 - T1 P = 80 x T + 0.55 x mc (T2-T0)/52

Room temperature ................................................................... To = 21°C

Initial temperature ..................................................................... T1 = 11°C

Temperature after (52 + 3) = 55 sec. ..................................... T2 = 21°C

Temperature difference Cold-Warm ( T = T2 - T1) .......... T = 10°C

Measured output power

The equation is "P = 80 x T" .................... P = 80 x 10°C = 800 Watts

[5] CHECKING TEMPERATURE IN THE CONVECTION (Oven) MODE

The following test procedure should be carried out with the oven is a fully assembled condition (outer case fitted).

It is difficult to measure the exact temperature in the convection oven. An accurate thermocouple type temperature tester must be used. A low priced
bi-metal type thermometer is not reliable or accurate. Position the thermocouple in the center of the oven cavity. The temperature should be checked
with outer case cabinet installed and set the oven temperature to 250°C in the convection mode (Oven). Approx. 15 minutes after the oven is started,
the temperature experienced may be approx. 15°C more or less than set temperature, however, in most cases the food cooking results will be satis­factory. Difference in power supply voltage will also affect the oven temperature. The Household power supply voltage may sometimes become lower
than the rated voltage and cause under-cooking. If the power supply voltage is 10% lower than the rated voltage, longer cooking time is required by
10% to 20%.

2. Insert a spacer of 0.8mm in thickness between the door sealer sec­tion (lower portion) and the front plate.

3. Adjust the door by moving it so that the door is parallel with the
oven cavity front plate lines (right and left side lines) and the door
latch heads pass through the latch holes correctly.

4. Tighten the screws holding the right oven hinge to the bottom plate.
Then tighten the screws holding the left oven hinge to the bottom
plate.

5. Adjust the latch (see [8]).

NOTE: In order to prevent deformation of parts, lay a soft mat and

then turn the unit on it.

1. After adjustment, make sure of the following:

1. The door latch heads smoothly catch the latch hooks through latch
holes and the latch heads goes through center of latch holes.

2. The door is positioned with its face pressed toward oven cavity
front plate.

3. Reinstall the outer case cabinet and check for microwave leakage
around the door with an approved microwave survey meter. (Refer
to Microwave Measurement Procedure.)

NOTE: The door on a microwave oven is designed to act as an elec-

tronic seal preventing the leakage of microwave energy from
the oven cavity during cook cycle. This function does not
require that the door be airtight, moisture (condensation)-tight
or light-tight. Therefore, occasional appearance of moisture,
light or 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 exhaust the vapor-laden air from the
oven cavity.

CHAPTER 8. MICROWAVE MEASUREMENT

After adjustment of door latch switches, monitor switch and door are 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 performance standard for microwave oven.

REQUIREMENT

The safety switch must prevent microwave radiation emission in excess of 5mW/cm

2

at any point 5cm or more from external surface of the oven.

PREPARATION FOR 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 instrumentations as prescribed by the performance standard for microwave ovens must
be used for testing.

Recommended instruments are:

NARDA 8100

NARDA 8200

HOLADAY HI 1500

SIMPSON 380M

2. Place the oven tray into the oven cavity.

3. Place the load of 275 ±15ml of water initially at 20 ±5°C in the centre of the oven tray. The water container should be a low form of 600 ml beaker
with inside diameter of approx. 8.5cm and made of an electrically non-conductive 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.

4. 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 cool water.

5. Move the probe slowly (not faster that 2.5cm/sec.) along the gap.

6. The microwave radiation emission should be measured at any point of 5cm or more from the external surface of the oven.
