PRECAUTIONS TO BE OBSERVED BEFORE AND DURINGSERVICING TOAVOID POSSIBLE EXPOSURE TO EXCESSIVEMICROWAVE ENERGY

1. Precaution

1-1 Safety precautions ( )

Follow these special safety precautions. Although the microwave oven is completely safe during ordinaryuse, repair work can be extremely hazardous due to possible exposure to microwave radiation, as well aspotentially lethal high voltages and currents.

1. All repairs should be done in accordancewith the procedures described in thismanual. This product complies withFederal Performance Standard 21 CFR Subchapter J (DHHS).

2. Microwave emission check should beperformed to prior to servicing if the oven isoperative.

3. If the oven operates with the door open :Instruct the user not to operate the oven andcontact the manufacturer and the center fordevices and radiological health immediatly.

4. Notify the Central Service Center if themicrowave leakage exceeds 5 mW/cm2

5. Check all grounds.

6. Do not power the MWO from a "2-prong"AC cord. Be sure that all of the built-inprotective devices are replaced. Restore anymissing protective shields.

7. When reinstalling the chassis and itsassemblies, be sure to restore all protectivedevices, including: nonmetallic controlknobs and compartment covers.

8. Make sure that there are no cabinet openingsthrough which people--particularlychildren--might insert objects and contactdangerous voltages. Examples: Lamp hole,ventilation slots.

9. Inform the manufacturer of any oven foundto have emmission in excess of 5 mW/cm2,Make repairs to bring the unit intocompliance at no cost to owner and try todetermine cause.Instruct owner not to use oven until it hasbeen brought into compliance.

CENTRAL SERVICE CENTER

10. Service technicians should remove theirwatches while repairing an MWO.

11. To avoid any possible radiation hazard,replace parts in accordance with the wiringdiagram. Also, use only the exactreplacements for the following parts:Primary and secondary interlock switches,interlock monitor switch.

12. If the fuse is blown by the Interlock MonitorSwitch: Replace all of the following at thesame time: Primary and secondary switches,as well as the Interlock Monitor Switch. Thecorrect adjustment of these switches isdescribed elsewhere in this manual. Makesure that the fuse has the correct rating forthe particular model being repaired.

13. Design Alteration Warning:Use exact replacement parts only, i.e.,only those that are specified in thedrawings and parts lists of this manual.This is especially important for theInterlock switches, described above.Never alter or add to the mechanical orelectrical design of the MWO. Any designchanges or additions will void themanufacturer's warranty. 10.Always unplugthe unit's AC power cord from the ACpower source before attempting toremove or reinstall any component orassembly.

14. Never defeat any of the B+ voltageinterlocks. Do not apply AC power to theunit (or any of its assemblies) unless allsolid-state heat sinks are correctly installed.

15. Some semiconductor ("solid state") devicesare easily damaged by static electricity. Suchcomponents are called ElectrostaticallySensitive Devices (ESDs). Examples includeintegrated circuits and field-effecttransistors.

Immediately before handling anysemiconductor components or assemblies,drain the electrostatic charge from yourbody by touching a known earth ground.

16. Always connect a test instrument's groundlead to the instrument chassis ground beforeconnecting the positive lead; always removethe instrument's ground lead last.

- 2 -

17.When checking the continuity of theswitches or transformer, always make surethat the power is OFF, and one of the leadwires is disconnected.

18. Use replacement components that have thesame ratings, especially for flame resistanceand dielectric strength specifications. Areplacement part that does not have thesame safety characteristics as the originalmight create shock, fire or other hazards.

1. High Voltage WarningDo not attempt to measureany of the highvoltages--this includes the filament voltageof the magnetron. High voltage is presentduring any cook cycle.

Before touching any components or wiring,always unplug the oven and discharge thehigh voltage capacitor (See Figure 1-1)

2. The high-voltage capacitor remains chargedabout 30 seconds after disconnection. Shortthe negative terminal of the high-voltagecapacitor to the oven chassis. (Use ascrewdriver.)

3. High voltage is maintained within specifiedlimits by close-tolerance, safety-relatedcomponents and adjustments. If the highvoltage exceeds the specified limits, checkeach of the special components.

Pretaution

1-2 Special Servicing Precautions (Continued)

1-3 Special High Voltage Precautions

PRECAUTION

There exists HIGH VOLTAGE ELECTRICITY with highcurrent capabilities in the circuits of the HIGH VOLTAGETRANSFORMER secondary and filament terminals. It isextremely dangerous to work on or near these circuitswith the oven energized.DO NOT measure the voltage in the high voltage circuitincluding filament voltage of magnetron.

PRECAUTION

Never touch any circuit wiring with your hand nor with aninsulated tool during operation.

PRECAUTIONServicemen should remove their watches wheneverworking close to or replacing the magnetron.

=> : Touch chassis side first then short to the high voltagecapacitor terminal by using a screwdriver or jumperwire.

2-1. High Vltage Capacitor

2. Alignmment and Adjustments

2-2 High Voltage Diode

2-3 Main Relay and Power Control Relay

2-4 Adjustment of Primary Switch, Door Sensing Switch and Monitor Switch

1. Check continuity of the capacitor with the meter set at the highest resistance scale.2. Once the capacitor is charged, a normal capacitor shows continuity for a short time, and then indicates 9M��3. A shorted capacitor will show continuous continuity.4. An open capacitor will show constant 9M

5. Resistance between each terminal and chassis should read infinite.

1. Isolate the diode from the circuit by disconnecting its leads.2. With the ohm-meter set at the highest resistance scale, measure across the diode terminals. Reverse the

meter leads and read the resistance. A meter with 6V, 9V or higher voltage batteries should be used tocheck the front-to back resistance of the diode (otherwise an infinite resistance may be read in bothdirections). The resistance of a normal diode will be infinite in one direction and several hundred K � in

the other direction.

1. When mounting Primary switch and InterlockMonitor switch to Latch Body, consult thefigure.

NOTE:No specific adjustment duringinstallation of Primary switch and Monitorswitch to the latch body is necessary.

2. When mounting the Latch Body to the ovenassembly, adjust the Latch Body by moving it sothat the oven door will not have any play in it.Check for play in the door by pulling the doorassembly. Make sure that the latch keys movesmoothly after adjustment is completed.Completely tighten the screws holding the LatchBody to the oven assembly.

3. Reconnect to Monitor switch and check thecontinuity of the monitor circuit and all latchswitches again by following the components testprocedures.

4. Confirm that the gap between the switchhousing and the switch actuator is no more than0.5mm when door is closed.

1. The relays are located on the PCB Ass'y. Isolate them from the main circuit by disconnecting the leads. 2. Operate the microwave oven with a water load in the oven. Set the power level set to high.3. Check continuity between terminals of the relays after the start pad is pressed.

Precaution

For continued protection against radiation hazard, replace parts in accordance with the wiring diagram and be sure to use thecorrect part number for the following switches: Primary and door sensing switches, and the interlock monitor switch (replace alltogether). Then follow the adjustment procedures below. After repair and adjustment, be sure to check the continuity of allinterlock switches and the interlock monitor switch.
