3. 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.

3.1. Check the grounding
Donot operate on a 2-wire extension cord. The microwave ovenis designedtobe usedwhen
grounded. It is imperative, therefore, tomake sure it is groundedproperlybefore beginning
repairwork.
3.2. 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.
3.3. When parts must be replaced, remove the power plug from the
outlet.
3.4. When the 8Amp fuse isblowndue to the operation of short
switch:
6

WARNING
Whenthe 8 Ampfuse is blowndue tothe operation
of short switch, you must replace Primarylatch
switchand short switch. Alsoreplace powerrelay
B (RY1) whenthe continultycheck reads shorted
contacts(1-2).
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.
3.5. 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.
3.6. 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.
CAUTION / MICROWAVE RADIATION
DO NOTBECOME EXPOSED TO RADIATION
FROM THE MICROWAVE GENERATOR 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 on these portions.
2.Whenthe appliance is operatedwiththe door
hinge ormagnetron fixedincorrectly, the
microwave leakage canreachmore than5mW/cm2.
Afterrepairorexchange, it is veryimportant to
check if magnetron and the doorhinge is correctly
fixed.
3.7. Sharp edges
CAUTION
Please use caution whenunpacking, installing or
moving the unit, as some exposededges maybe
sharptotouchand cause injuryif not handledwith
care.
4. MEASUREMENTS AND ADJUSTMENTS
4.1. Adjustment of primarylatch switch, secondarylatch switch and
short switch.
1. When mounting Primarylatch switch,Secondarylatch switch and
short switch to door hook assembly, mount the Primarylatch
swith, the Secondarylatch switch and the short switch to the door
hook assemblyas shownintable.
NOTE:
Nospecificadjustment during installation of Primarylatch
switch,Secondarylatch switch and short switch to the door hook
isnecessary.
2. When mounting the door hook assemblyto the oven assembly,
adjust the door hook assemblybymoving itinthe direction of
arrow inthe 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
8

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
components test procedures.
4.2. 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 beaker’stemperature.
(recorded as T1).
2. Place the beaker on the center of glass cook plate. / Set the oven
9

for High power and heat itfor exactlyone minute.
3. Stirthe water againand read the temperature of the beaker.
(recorded as T2).
4. The normal temperature rise at High power position for each
model isas shownintable.
