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.
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.
8. Remove the bottom plate assembly, referring to “BOTOM PLATE ASSEMBLY” in page 8-4.
9. Disconnect the leads to the primary of the inverter unit.
10.Ensure that the leads remain isolated from other components and oven chassis by using insulation tape.
11.After that procedure, reconnect the power supply cord.
[2] When the testing is completed,
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.

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.
8. Reconnect all leads removed from components during testing.
9. Reinstall the outer case and the back plate assembly.
10.Reconnect the power supply cord after the outer case and the back plate assembly are installed.
11.Run the oven and check all function.
[3] After repairing
1. Reconnect all leads removed from components during testing.
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.
PWB CONNECTOR Symptom
CONTROL UNIT CN-A The oven cannot be powered on.
CN-B No heating can be done (even if the door or thermistor has not been opened). No cooling fan runs. CN-D No indication, no key insertion and no buzzer sound. CN-E The oven cannot be powered on, no fan motor runs and no oven lamp illuminate. CN-G No heating can be done. (Humidity sensor error)

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 suf­fixletter 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
AAs the melting point of lead-free solder (Sn-Ag-Cu, Sn-Cu-Ni) is higher and has poorer wettability, (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.

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. Check in the event of a fuse 20A blowing
When the fuse F10A was blown, observe the following instruction:
There are many high voltage components in the oven, therefore, except for performing operational check, unplug the power cable before starting work. For the harness, check for poor caulking, poor connection, etc.
3. Check in the event of no microwave cooking
Check of high voltage sections is very dangerous. Therefore, after the inverter boards (M and AC3) and 110V at the primary terminal are confirmed to be satisfactory, disconnect the main power and wait for at least one (1) minute before starting the check.
Check of individual components is done with the high voltage circuit wiring disconnected.
*1 Disconnect only the inverter unit terminals M and AC3. Then measure voltage between CN-A pins #1 and #3 (between PD 100 2P and 1P) with an
analog tester while performing heating operation.
*2 If a value measured by a digital tester is unstable, connect a resistor of 10 kΩ to 100 kΩ between the pins #1 and #3 to measure the value.

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.

2. TREATMENT AFTER ENGINE UNIT REPLACE-
MENT
After the new engine unit assembly is installed, carry out the following three procedures to avoid the error operation.
1. At first, fill the tank assembly with water and carry out
(steam cooking)” with manual operation for about five (5) minutes, referring to operation manual.
2. Then, carry out “ (drain water function)”.
3. At last, fill the tank assembly with water and carry out
(steam cooking)” again for about ten (10) minutes. And check that the error does not appear on the display.
4. If the error is appeared and the oven stops at above step 1, carry out step 2 and step 3.
REASON
Inside walls of the engine unit assembly have been painted to protect the engine unit assembly with special paint. And special paint will shed water initially. By carrying out Steam cooking, paint can be accus­tomed to water. If this operation is not carried out, the oven will judge that there is no water in the tank assembly. And the display will show the error and then the oven will stop.
Because this oven judges that there is water or not by checking on/off time ratio of the engine unit assembly.
If paint is not accustomed to water, off time will become longer than on time. At this time, the oven will judge no water.

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.
