CHAPTER 2. MICROWAVE MEASUREMENT PROCEDURE

A. Requirements:

1) Microwave leakage limit (Power density limit): The power density of microwave radiation emitted by a microwave oven should not exceed 1mW/ cm 2 at any point 5cm or more from the external surface of the oven, measured prior to acquisition by a purchaser, and thereafter (through the useful life of the oven), 5 mW/cm 2 at any point 5cm or more from the external surface of the oven.

2) Safety interlock switches: Primary interlock relay and door sensing switch shall prevent microwave radiation emission in excess of the requirement as above mentioned, secondary interlock switch shall prevent microwave radiation emission in excess of 5 mW/cm 2 at any point 5cm or more from the external surface of the oven.

B. Preparation for testing:

Before beginning the actual measurement of leakage, proceed as follows:

1) Make sure that the actual 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, 21 CFR

1030.10(c)(3)(i), must be used for testing.

2) Place the oven tray in the oven cavity.

3) Place the load of 275 ±5 ml (9.8 oz) of tap water initially at 20±5°C (68°F) in the center of the oven cavity.

The water container shall be a low form of 600 ml (20 oz) beaker with an inside diameter of approx. 8.5 cm (3-1/2 in.) 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.

4) Set the cooking control on Full Power Cooking Mode

5) Close the door and select a cook cycle of several minutes. If the water begins to boil before the survey is completed, replace it with 275 ml of cool water.

C. Leakage test:

Closed-door leakage test (microwave measurement)

1) Grasp the probe of the survey instrument and hold it perpendicular to the gap between the door and the body of the oven.

2) Move the probe slowly, not faster than 1 in./sec. (2.5 cm/sec.) along the gap, watching for the maximum indication on the meter.

3) Check for leakage at the door screen, sheet metal seams and other accessible positions where the continuity of the metal has been breached (eg., around the switches, indicator, and vents).

While testing for leakage around the door pull the door away from the front of the oven as far as is permitted by the closed latch assembly.

4) Measure carefully at the point of highest leakage and make sure that the highest leakage is no greater than 4mW/cm 2 , and that the secondary interlock switch and the primary interlock relay do turn the oven OFF before any door movement.

NOTE: After servicing, record data on service invoice and microwave leakage report.

Service Manual

[1] DESCRIPTION OF OPERATING SEQUENCE

The following is a description of component functions during oven operation.

1. OFF CONDITION

(For details, refer to Figure O-1)

Closing the door activates the door sensing switch and secondary interlock switches (1), (2). (In this condition, the monitor switches (1) &

(2) contacts are opened.) When the oven is plugged in, and the rated voltage is supplied to the switching power supply unit through the noise filter, (figure O-1). The switching supply unit supplies D.C. voltage (approx. 24V) to the relay unit. And the display will show “ . “.

2. COOKING CONDITION

(For details, refer to Figure O-2)

Press SELECT TIME pad. Enter cooking time by pressing the number pads. Press the SELECT POWER pad. Enter power level by pressing the number pad. When the START pad is pressed, the following operations occur:

1. The contacts of relays are closed. And the oven lamp and the antenna motors connected to the relays are turned on (For details, refer to Figure O-2).

2. D.C. voltage is supplied to the fan motors, exhaust fan and exhaust motor from the control unit.

3. Rated voltage is supplied to the primary winding of the power transformer and is converted to about 3.17 volts output on the filament winding, and approximately 2240 volts on the high voltage winding.

4. The filament winding voltage heats the magnetron filament and the

H.V. winding voltage is sent to a voltage doubler circuit.

5. The microwave energy produced by the magnetron is channelled through the waveguide into the cavity feed-box, and then into the cavity where the food is placed to be cooked.

6. Upon completion of the cooking time, the oven will revert to the

OFF condition. The fan motors, exhaust fan and the exhaust motor will operate at least for 1 minute.

7. When the door is opened during a cook cycle, monitor switches (1)

& (2), door sensing switch, secondary interlock switches (1), (2) and primary interlock relay are activated with the following results.

The circuits to the high voltage components are de-energized.

8. The monitor switch (1) is electrically monitoring the operation of the secondary interlock switch (1) and primary interlock relay, and monitor switch (2) is electrically monitoring the operation of the secondary interlock switch (2) and primary interlock relay, and monitor switches (1), (2) are mechanically associated with the door so that it will function in the following sequence.

1) (1) When the door opens from a closed position, the contacts of the primary interlock relay and secondary interlock switches (1),

(2) open. Then the monitor switch contacts close.

2) (2) When the door is closed from the open position, the monitor switches (1), (2) contacts first open, and then the contacts of the secondary interlock switches (1), (2) close.

If the secondary interlock switches (1), (2) and primary interlock relay fail with their contacts closed when the door is opened, the closing of the monitor switches (1), (2) contacts will form a short circuit through the monitor fuse, secondary interlock switches (1), (2) and primary interlock relay, causing the monitor fuse to blow.

3. DOOR OPEN CONDITION

When the door is opened, the contacts of the door sensing switch open, initiating the following:

1. A signal is input to the control unit energizing the coil of shutoff relay (RY-4).

2. The shut-off relay (RY-4) contacts close completing circuits to turn on the oven lamp and antenna motors.

3. If the door remains open, 60 seconds later the control unit de-energizes shut-off relay (RY-4) turning off the oven lamp and antenna motors.

4. VARIABLE POWER COOKING

When Variable Cooking Power is programmed, the rated voltage A.C.

is supplied to the power transformer intermittently through the contacts of relay (RY-2, RY-3). Relays RY-2 and RY-3 are operated by the control unit within an interval 48 second time base. Microwave power operation is as follows:

Figure D-1. Door Open Mechanism

2. DOOR SENSING SWITCH

The door sensing switch is activated by the latch head of the door and switch lever C. When the door is opened, the contacts of the switch open and interrupt the circuit to the coils of the primary interlock relay.

The contacts of the primary relay then open and interrupt the circuit to the primary winding of the power transformers.

3. SECONDARY INTERLOCK SWITCHES (1), (2)

The secondary interlock switches (1), (2) are activated by the upper latch head of the door and switch lever B. When the door is opened, the contacts of the switch open and interrupt the circuit to the primary winding of the power transformers (1), (2).

4. MONITOR SWITCHES (1), (2)

The monitor switches (1), (2) are mounted in the upper position of the latch hook. The monitor switches are activated by the upper latch head of the door and switch lever A. When the door is opened, the contacts of the monitor switches close. Monitor switch (1) is intended to render the oven inoperative by means of blowing the monitor fuse, when the contacts of the primary interlock relay and secondary interlock switch

(1) fail to open when the door is opened. Monitor switch (2) is intended to render the oven inoperative by means of blowing the monitor fuse, when the contacts of the primary interlock relay and secondary interlock switch (2) fail to open when the door is opened.

Functions:

With the door shut, the contacts of the door sensing switch and the secondary interlock switches (1), (2) are closed and the contacts of the monitor switches (1), (2) are open.

1. When the door is opened, the contact of the door sensing switch and secondary interlock switches (1), (2) are opened first, then the contact of the monitor switches (1), (2) are closed.

2. As the door goes to a closed position, the contacts of the monitor switches (1), (2) are opened first, then the contacts of the door sensing switch and the secondary interlock switches (1), (2) close.

3. If the door is opened, and the contacts of the primary interlock relay and secondary interlock switch of the same circuit fail to open, the monitor fuse blows simultaneously with closing of the monitor switch contacts of that circuit (1 or 2).

TER “TEST PROCEDURE”).

NOTE: MONITOR FUSE AND SWITCH ARE REPLACED AS AN

ASSEMBLY.

5. MONITOR FUSE

1. The monitor fuse blows when the contacts (COM-NO) of the primary interlock relay (RY1) and secondary interlock switch remain closed with the oven door open and when the monitor switch closes.

2. If the wire harness or electrical components are short-circuited, this monitor fuse blows to prevent an electric shock or fire hazard.

6. MAGNETRON TEMPERATURE FUSES (1), (2)

The temperature fuses (1), (2) located on the top of the upper and lower waveguide, are designed to prevent damage to the magnetrons

(1), (2). If an over heated condition develops in the tube due to blower motor failure, obstructed air ducts, dirty or blocked air intake, etc., the circuit to the magnetrons are interrupted. Under normal operation, the temperature fuses remains closed. However, when abnormally high temperatures are generated within the magnetron, the temperature fuse will open at 302 °F (150°C) causing the microwave energy to stop.

The defective temperature fuse must be replaced with new rated one.

7. OVEN TEMPERATURE FUSE

The temperature fuse, located on the side of the exhaust duct assembly, is designed to prevent damage to the oven by fire. If the food load is overcooked, by either error in cook time or defect in the control unit, the temperature fuse will open. Under normal operation, the oven temperature fuse remains closed. However, when abnormally high temperatures are generated within the oven cavity, the oven temperature fuse will open at 248 °F (120°C), causing the oven to shut down. The defective temperature fuse must be replaced with new rated one.

8. EXHAUST THERMISTOR

The exhaust thermistor is located on the side of the exhaust duct assembly. The temperature in the exhaust duct is detected through the resistance of the thermistor. If the temperature is high, the control panel will display”EE7” and the oven will stop to avoid overheating and catching fire. If the thermistor is open, the control panel will display

“EE8” and the oven will stop.

9. MAGNETRON THERMISTOR

The thermistor is a negative temperature coefficient type. The air temperature around the upper and lower magnetrons is detected through the resistance of the thermistor. If the temperature is high, the control panel will display “EE7” and the oven will stop to protect the magnetrons against overheat. If the magnetron thermistor is open, the control panel will display “EE8” and the oven will stop.

10. FAN MOTORS

The fan motors drive blades which draw external cool air into the oven.

This cool air is directed through the air vanes surrounding the magnetrons and cools the magnetrons. This air is channelled through the oven cavity to remove steam and vapours given off from the heating foods. It is then exhausted through the exhausting air vents at the oven cavity.

5 – 3

RCD2200M

During cooking, they operate. After cooking, they will operate at least for 1 minute and the maximum operating time is 4 minutes. When the temperature of the magnetron thermistor becomes bellow 110 °C, the fan motors will stop. These two (2) fan motors are D.C. motors.

11. EXHAUST MOTOR

The exhaust motor is located on the side of the exhaust duct assembly. This motor drives a blade in the exhaust duct assembly. The driven blade draws the external cool air into the oven from the intake duct assembly. Then it sends the air out of the oven through the exhaust duct assembly. During cooking, the exhaust motor operates.

After cooking, it will operate at least for 1 minute and the maximum operating time is 4 minutes. When the temperature of the exhaust thermistor becomes bellow 65 °C, the exhaust motor will stop. This motor is D.C. motor.

NOTE: Do not disconnect the power supply from the exhaust motor when it is turned on. Or it may be out of order.

12. ANTENNA MOTORS

The upper and lower antenna motors drive antennas to radiate the microwave.

13. EXHAUST FAN

The exhaust fan is located to the rear cover. It sends the air (which is at the top of the oven cavity) out of the oven. This motor is D.C. motor.

14. ANTENNA SENSOR

The antenna sensors are located to the top and bottom of the oven cavity. And they watch if the antennas are rotating or not.

15. MIROWAVE SENSOR

The microwave sensor is located on the top of the oven cavity. And it watch if the microwave is radiated into the oven cavity or not.

16. FUSE 12A (1) (2)

1. If the wire harness or electrical components are short-circuited, this fuse blows to prevent an electric shock or fire hazard.

2. The fuse also blows when the asymmetric rectifier, H.V. rectifier,

H.V. wire harness, H.V. capacitor, magnetron or secondary winding of high voltage transformer is shorted.

17. H.V. ASYMMETRIC RECTIFIER (1) (2)

The H.V.asymmetric rectifiers (1) (2) are solid state devices that prevent current flow is both directions. And they prevent the temperature rise of the high voltage transformers (1) (2) by blowing the fuses 12A

(1) (2) when the high voltage rectifiers (1) (2) are shorted. The rated peak reverse voltage of D1 of the asymmetric rectifier is 6 KV. The rated peak reverse voltage of D2 of the asymmetric rectifier is 1.7 KV.

D1 and D2 of the asymmetric rectifier or high voltage rectifier are shorted when the each peak reverse voltage goes beyond the each rated peak reverse voltage. (The process of the blowing the fuse 12A.)

RCD2200M


Never touch any part in the circuit with your hand or an uninsulated tool while the power supply is connected.

When troubleshooting the microwave oven, it is helpful to follow the Sequence of Operation in performing the checks. Many of the possible causes of trouble will require that a specific test be performed. These tests are given a procedure letter which will be found in the “Test Procedure“ section.

IMPORTANT:

If the oven becomes inoperative because of a blown monitor fuse, check the monitor switches (1), (2), primary interlock relay RY1, door sensing switch and secondary interlock switches (1), (2), before replacing the monitor fuse. If monitor fuse is replaced, the monitor switch (1) and/or (2) must also be replaced. Use part FFSBA033WRKZ as an assembly.

IMPORTANT:

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



3. Discharge two high voltage capacitors.

4. Disconnect the leads to the primaries of the two power transformers.

5. Ensure that the leads remain isolated from other components and oven chassis by using insulation tape.

6. After that procedure, reconnect the power supply cord.

When the testing is completed




4. Reconnect the all leads removed from components during testing.

Service Manual

[1] A: MAGNETRON ASSEMBLY TEST

1. Disconnect the power supply cord, and then remove outer case and rear cover.



4. 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.

5. 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.


7. Reinstall the rear cover and the outer case (cabinet).



1. MICROWAVE OUTPUT POWER

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

HIGH VOLTAGES ARE PRESENT DURING THE COOK CYCLE, SO EXTREME CAUTION SHOULD BE OBSERVED.

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: silicon rectifier, high voltage capacitor and power transformer.

This test will require a 16 ounce (453cc) measuring cup and an accurate mercury thermometer or thermocouple type temperature tester. For accurate results, the following procedure must be followed carefully:

1. Fill the measuring cup with 16 oz. (453cc) of tap water and measure the temperature of the water with a thermometer or thermocouple temperature tester. Stir the thermometer or thermocouple through the water until the temperature stabilizes. Record the temperature of the water.

2. Place the cup of water in the oven. Operate oven at 100% Power selecting more than 60 seconds cook time. Allow the water to heat for 60 seconds, measuring with a stop watch, second hand of a watch or the digital read-out countdown.

3. Remove the cup from the oven and again measure the temperature, making sure to stir the thermometer or thermocouple through the water until the maximum temperature is recorded.

4. Subtract the cold water temperature from the hot water temperature. The normal result should be 49 to 91.1

°F (27.2 to 50.6°C) rise in temperature for R-CD18MP. The normal result should be 59 to 109.8

°F (32.8 to 61°C) rise in temperature for R-CD22MP. If the water temperatures are accurately measured and tested for the required time period the test results will indicate if the magnetron tube has low power output (low rise in water temperature) which would extend cooking time or high power output (high rise in water temperature) which would reduce cooking time. Because cooking time can be adjusted to compensate for power output, the magnetron tube assembly should be replaced only if the water temperature rise test indicates a power output well beyond the normal limits. The test is only accurate if the power supply line voltage is 208/230 volts and the oven cavity is clean.

.

[2] B: POWER TRANSFORMER TEST




4. 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 be less than 1 ohm and the resistance of the high voltage coil should be approximately 58 ohms; the resistance of the filament coil should be less than 1 ohm.





(HIGH VOLTAGES ARE PRESENT AT THE HIGH VOLTAGE TERMINAL, SO DO NOT ATTEMPT TO MEASURE THE FILAMENT AND HIGH

VOLTAGE.)

RCD2200M

4. Isolate the high voltage rectifier assembly from the HV circuit. The high voltage rectifier can be tested using an ohmmeter set to its highest range.

Connect the ohmmeter across the terminal B+C of the high voltage rectifier and note the reading obtained. Reverse the meter leads and note this second reading. The normal resistance is infinite in one direction and more than 100k ohms in the other direction.



7. Reconnect the power supply cord after the rear cover and the outer case are installed.

4. Isolate the high voltage rectifier assembly from the HV circuit. The asymmetric rectifier can be tested using an ohmmeter set to its highest range across the terminals A+B of the asymmetric rectifier and note the reading obtained. Reverse the meter leads and note this second reading. If an open circuit is indicated in both directions then the asymmetric rectifier is good. If the asymmetric rectifier is shorted in either direction, then the asymmetric rectifier is faulty and must be replaced with high voltage rectifier. When the asymmetric rectifier is defective, check whether magnetron, high voltage rectifier, high voltage wire or filament winding of the high voltage transformer is shorted.





NOTE: Be sure to use an ohmmeter that will supply a forward bias voltage of more than 6.3 volts.

[4] D: HIGH VOLTAGE CAPACITOR (1) AND/OR (2) TEST




4. 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 an ohmmeter to see if it is shorted between either of the terminals and case. If it is shorted, replace the capacitor.





[5] E: SECONDARY INTERLOCK SWITCH (1) AND/OR (2) TEST

1. Disconnect the power supply cord, and then remove outer case and rear cabinet.



4. Isolate the switch and connect the ohmmeter to the common (COM.) and normally open (NO) terminal of the switch. The meter should indicate an open circuit with the door open and a closed circuit with the door closed. If improper operation is indicated, replace the secondary interlock switch.





7 – 2

RCD2200M

[6] F: PRIMARY INTERLOCK SYSTEM TEST

1. DOOR SENSING SWITCH




4. Isolate the switch and connect the ohmmeter to the common (COM.) and normally open (NO) terminal of the switch. The meter should indicate an open circuit with the door open and a closed circuit with the door closed. If improper operation is indicated, replace the door sensing switch.





NOTE: If the door sensing switch contacts fail in the open position and the door is closed, the blower motor, stirrer motors and oven light will be activated by RY1.

2. PRIMARY INTERLOCK RELAY RY1




4. Disconnect two (2) wire leads from the male tab terminals of the Primary Interlock Relay RY1. Check the state of the relay contacts using a ohmmeter. The relay contacts should be open. If the relay contacts are closed, replace the circuit board entirely or the relay itself.





[7] G: MONITOR SWITCH (1) AND/OR (2) TEST




4. Before performing this test, make sure that the secondary interlock switches (1), (2) and the primary interlock relay RY1 are operating properly, according to the above Switch Test Procedure. Disconnect the wire lead from the monitor switches (1), (2) (COM) terminals. Check the monitor switches (1), (2) operation by using the ohmmeter as follows. When the door is open, the meter should indicate a closed circuit. When the monitor switch actuator 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, the switch may be defective. After testing the monitor switches, reconnect the wire lead to the monitor switch (COM) terminals and check the continuity of the monitor circuit.

5. Set of standard voltage (SF-7)

When the control unit or the relay unit is replaced, set the standard voltage, referring to following procedure. Because the control unit judges if the AC supply voltage is 230V or 208V by comparing with the standard voltage. The temporary standard voltage is set when the oven is shipped from the factory. But when the control unit is replaced to new one, it does not have the standard voltage. When the relay unit is replaced to new one, set the standard voltage too. Because the signal from the relay unit to detect the AC supply voltage has error of ±5%.

The standard voltage can be set by using this function.

For example: Procedure to set the standard voltage (in case input voltage is 230V ±1V)

When the oven detects the AC voltage is 208V, the control unit calculates that the standard voltage is 219V. Because 208V + 11V = 219v.

NOTE: 11V is not exact.

For example: In case that AC supply voltage is out of range from tentative memorized voltage (standard voltage ±13%), the display will show “----” as follows.

At that time, the voltage of AC power may be not suitable or the control unit and /or the relay unit may be out of order.

[2] SERVICING FOR BRINTED WIRING BOARDS

1. Precautions for Handling Electronic Components

This unit uses CMOS LSI in the integral part of the circuits. When handling these parts, the following precautions should be strictly followed.

CMOS 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 charge in clothes, etc. and sometimes it is not fully protected by the built-in protection circuit.

In order to protect CMOS LSI.

1) When storing and transporting, thoroughly wrap them in aluminium 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.

approx. 1M ohm

2. Servicing of Printed Wiring Boards

We describe the procedures to permit servicing of the printed wiring boards of the microwave oven and the precautions you must take when doing so. To perform the servicing, power to the printed wiring boards is available either from the power line of the oven itself or from an external power source.

1. Servicing the printed wiring boards with power supply of the oven:

CAUTION: THE HIGH VOLTAGE TRANSFORMER OF THE MICRO-

WAVE OVEN IS STILL LIVE DURING SERVICING AND

PRESENTS A HAZARD.

Therefore, before checking the performance of the printed wiring boards,

1) Disconnect the power supply cord and then remove outer case and rear cover.



4) Disconnect the leads to the primary of the two power transformers.

5) Ensure that these leads remain isolated from other components and oven chassis by using insulation tape.

6) After that procedure, re-connect the power supply cord.

After checking the performance of the printed wiring boards,

1) Disconnect the power supply cord.


3) Re-connect the leads to the primary of the two power transformers.

4) Re-install the rear cover and the outer case (cabinet).

5) Re-connect the power supply cord after the rear cover and the outer case is installed.

6) Run the oven and check all functions.

a) On some models, the power supply cord between the printed wiring boards and the oven itself is so short that the they can’t be separated. For those models, check and repair all the printed wiring boards (sensor-related ones included) of the printed wiring boards while keeping it connected to the oven.

b) On some models, the power supply cord between the printed wiring boards and the oven proper is long enough that they may be separated from each other. For those models, it is possible to check and repair the controls of the printed wiring boards while keeping it apart from the oven proper; in this case you must short both ends of the door sensing switch

(on PWB) of the printed wiring boards with a jumper, which activates an operational state that is equivalent to the oven door being closed. As for the sensor-related controls of the printed wiring boards, checking them is possible if dummy resistor(s) with resistance equal to that of the controls are used.

2. Servicing the printed wiring boards with power supply from an external power source:

Disconnect the printed wiring boards completely from the oven proper, and short both ends of the door sensing switch (on PWB) of the printed wiring boards, which activates an operational state that is equivalent to the oven door being closed. Connect an external power source to the power input terminal of the printed wiring boards, then it is possible to check and repair the controls of the printed wiring boards it is also possible to check the sensor-related controls of the printed wiring boards by using the dummy resistor(s).

3. Servicing Tools

Tools required to service the printed wiring boards assembly.

1) Soldering iron: 60W

(It is recommended to use a soldering iron with a grounding terminal.)

2) Oscilloscope: Single beam, frequency range: DC - 10MHz type or more advanced model.

3) Others: Hand tools

4. Other Precautions

1) Before turning on the power source of the printed wiring boards, remove the aluminium foil applied for preventing static electricity.

2) Connect the connector of the key unit to the printed wiring boards being sure that the lead wires are not twisted.

3) After aluminium foil is removed, be careful that abnormal voltage due to static electricity etc. is not applied to the input or output terminals.

4) Attach connectors, electrolytic capacitors, etc. to PWB, making sure that all connections are tight.

5) Be sure to use specified components where high precision is required.

CHAPTER 9. 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:

Indicates lead-free solder of tin, silver and copper

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.

SWITCHES (1), (2) ADJUSTMENT

1. Adjustment procedure




If the door sensing switch, secondary interlock switches (1), (2) and monitor switches (1), (2) do not operate properly due to a misadjustment, the following adjustment should be made.

4. Loosen the two (2) screws holding latch hook to the oven cavity front flange.

5. With door closed, adjust latch hook by moving it back and forth, and up and down. In and out play of the door allowed by the upper and lower position of the latch hook should be less than 0.5mm.

The vertical position of the latch hook should be adjusted so that the door sensing switch and secondary interlock switches (1), (2) are activated with the door closed. The horizontal position of the latch hook should be adjusted so that the monitor switches (1), (2) are activated with the door closed.

6. Secure the screws with washers firmly.

7. Check the operation of all switches. If all switches have not activated with the door closed, loosen two (2) screws and adjust the latch hook position.

10 – 5

2. After adjustment, check the following.

1. In and out play of door remains less than 0.5mm when in the latched position.

2. The door sensing switch and secondary interlock switches (1), (2) interrupt the circuit before the door can be opened.

3. Monitor switches (1), (2) contacts close when door is opened.

4. Re-install outer case and check for microwave leakage around door with an approved microwave survey meter. (Refer to Microwave Measurement Procedure.)

1. REMOVAL




4. Disconnect the harness of the door assembly from the control unit.

5. Remove the two (2) screws holding each of the upper and lower hinges to the oven cavity.

6. Remove door assembly with upper and lower hinges by pulling it forward.

7. Release upper and lower hinges and the hinge cover from door assembly.

8. Now, door assembly is free.

NOTE: When individual parts are replaced, refer to “Door Disassembly”.


1. Install the hinge cover to the upper hinge. At this time, the harness of the door assembly should be passed through under the hinge cover.

2. Insert the upper and lower hinges into door hinge pins.

3. Insert the upper and lower hinges with door assembly into rectangular holes of oven cavity front plate.

4. Make sure that the door is parallel with oven face lines (left and upper side line) and door latch heads pass through the latch holes correctly.

5. Fasten upper and lower hinges firmly to oven cavity with two (2) screws on each hinge.

NOTE: After any service to the door;

1) Make sure that door sensing switch, secondary interlock switches (1), (2) and monitor switches (1), (2) are operating properly. (Refer to chapter “Test Procedures”.).

2) An approved microwave survey meter should be used to assure compliance with proper microwave radiation emission limitation standards.

3. DOOR ADJUSTMENT

Door adjustment is performed with the door properly installed and closed and while the oven hinges are loose.

1. Loosen upper and lower hinges with phillips head screw driver.

10 – 6

2. Adjust the door by moving it vertically so that the top of the door is parallel to the bottom of the control panel assembly.

3. Tighten the upper and lower oven hinge screws.

3.1. After adjustment, make sure of the following:

1. Door latch heads smoothly catch the latch hook through the latch holes, and the latch head goes through the center of the latch hole.

2. Deviation of the door alignment from horizontal line of cavity face plate is to be less than 1.0mm.

3. The door is positioned with its face depressed toward the cavity face plate.

4. Re-install outer case and check for microwave leakage around 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 electronic seal preventing the leakage of microwave energy from oven cavity during cook cycle.

This function does not require that door be air-tight, moisture

(condensation)-tight or light-tight. Therefore, occasional appearance of moisture, light or sensing of gentle warm air movement around oven door is not abnormal and do not of themselves, indicate a leakage of microwave energy from 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.
