1. SCHEMATIC DIAGRAM

1.1. NN-G315

1.2. NN-G335

2. CAUTIONS TO BE OBSERVED WHEN

TROUBLESHOOTING

Unlike manyotherappliances, the microwave ovenis high-voltage, high-current equipment.

Though it is free fromdangerinordinaryuse, extreme care shouldbe takenduring repair.

CAUTION

Servicemenshouldremove theirwatches

wheneverworking close toorreplacing the

magnetron.

2.1. Check the grounding

Donot operate on a 2-wire extension cord. The microwave ovenis designedtobe grounded

whenused. It is imperative, therefore, tomake sure it is groundedproperlybefore beginning

repairwork.

2.2. Warning about the electriccharge inthe high voltage capacitor

Forabout 30 seconds afterthe ovenis turnedoff, anelectric charge remains inthe high voltage

capacitor.Whenreplacing orchecking parts, remove the powerplug fromthe outlet and short

the terminal of the high voltage capacitor(terminal of leadwire fromdiode) tochassis ground

withaninsulatedhandle screwdrivertodischarge.

WARNING

There is high-voltage present, withhigh-current

capabilities inthe circuits of the high voltage

winding and filament winding of the high voltage

transformer. It is extremelydangerous towork on

ornearthese circuits withovenenergized. / DO

NOTmeasure the voltage inthe high voltage

circuit including filament voltage of magnetron.

WARNING

Nevertouchanycircuit wiring withyourhand nor

withaninsulatedtool during operation.

2.3. When parts must be replaced, remove the power plug from the

outlet.

2.4. When the 8Amp fuse isblowndue to the operation of short

switch:

WARNING

Whenthe 8 Ampfuse is blowndue tooperation of

the interlock monitorswitch, you must replace all

of the components (Primarylatchswitch, Door

switch, Short switchand PowerrelayB (RY1)).

1. Thisismandatory. Refer to “Adjustments and Measurement” for

these switches.

2. When replacing the fuse, confirm that ithas the appropriate rating

for these models.

3. When replacing faultyswitches, be sure mounting tabs are not

bent, broken or otherwise deficient intheirabilityto holdthe

switches.

2.5. Avoidinserting nails, wire, etc. through anyholes inthe unit

during operation.

Neverinsert a wire, nail oranyothermetal object through the lampholes on the cavityorany

otherholes orgaps, because suchobjects maywork as anantenna and cause microwave

leakage.

2.6. Confirm after repair

1. After repairor replacement of parts, make sure that the screwsof

the oven, etc. are neither loose nor missing. / Microwaves might

leak ifscrewsare not properlytightened.

2. Make sure that all electrical connections are tight before inserting

the plug into the wall outlet.

3. Check for microwave energyleakage. (Refer to procedure for

measuring microwave evergyleakage.)

CAUTION / MICROWAVE RADIATION

USE CAUTION NOTTO BECOME EXPOSED TO

RADIATION FROM THE MICROWAVE

MAGNETRON OR OTHER PARTS CONDUCTING

MICROWAVE ENERGY.

IMPORTANTNOTICE

1.The following components have potentials above

2000V while the appliance is operated.

*Magnetron

*High voltage transformer

*High voltage diode

*High voltage capacitor

Payspecial attention tothese areas.

2.Whenthe appliance is operatedwiththe door

hinge ormagnetron adjustedincorrectly, the

microwave leakage canexceedmore than5mW/cm

2. Afterrepairorexchange, it is veryimportant to

check that magnetron and the doorhinge is

correctlyinstalled.

3. MEASUREMENTS AND ADJUSTMENTS

3.1. Adjustment of Primarylatch switch, Secondarylatch switch and

Short switch.

1. Mount the Primarylatch swith, the Secondarylatch switch and the

Short switch to the door hook assemblyas showninILL.

NOTE:

Nospecificindividual adjustments during installation of the

Primarylatch switch, Secondarylatch switch or Short switch to

the door hook are required.

2. When mounting the door hook assemblyto the oven assembly,

adjust the door hook assemblybymoving itinthe direction of the

arrowsinthe illustration so that the oven door will not have any

playinit. Check for playinthe door bypulling the door assembly.

Make sure that the latch keysmove smoothlyafter adjustment is

completed. Completelytighten the screwsholding the door hook

assemblyto the oven assembly.

3. Reconnect the short switch and check the coninuityof the

monitor circuitand all latch switches againbyfollowing the

component test procedures.

3.2. Measurement of microwave output

The output powerof the magnetron canbe determinedbyperforming IEC standardtest

procedures. However, due tothe complexityof IEC test procedures, it is recommendedtotest

the magnetron using the simple method outlinedbelow.

NecessaryEquipment:

-1liter beaker

-Glass thermometer

-Wrist watch or stopwatch

NOTE:

Check the line voltage under load.Low voltage will lower the

magnetron output. Take the temperature readings and heating time

as accuratelyas possible.

1. Fill the beaker with exactlyone liter of tap water. Stirthe water

using the thermometer and record the water’stemperature.

(recorded as T1).

2. Place the beaker on the center of glass tray. / Set the oven for

High power and heat itfor exactlyone minute.

3. Stirthe water againand read the temperature of the water.

(recorded as T2).

4. The normal temperature rise at High power level for each model

isas shownintable.

NOTE:

1. When ordering replacement part(s), please use part number(s)

showninthispart list.

Donot use description of the part.

2. Important safetynotice:

Components identified bymark have special characteristics

important for safety.

When replacing anyof these components, use onlymanufacture’s

specified parts.
