WARNING
Nevertouchanycircuit wiringwithyourhandor withaninsulatedtool duringoperation.
3.3Partreplacement.
When any part or component is tobereplaced, always ensurethatthe powercordis removed from thewall outlet.
3.4Whenthe10Afuseisblown duetothe
operation oftheshortswitch:
WARNING
When the10A 250V fuseis blownduetotheoperationoftheinterlock monitor switch, replaceall ofthe components
(primary latchswitch, shortswitchandpower relayB (RY1)).
1. This is mandatory. Refer to“adjustments andmeasurements”forthelocation oftheseswitches.
2. When replacingthefuse,confirm that it has the appropriateratingforthesemodels.
3. When replacingfaulty switches,besurethemounting tabsarenotbent, brokenor deficientintheir ability tohold
theswitches.
3.5Avoidinsertingnails,wireetc.through any
holesintheunitduringoperation.
Neverinsert awire,nailorany other metal objectthroughthelampholes on thecavity or any holesorgaps,because
suchobjects may work asanantennaand causemicrowaveleakage.
3.6Confirmafterrepair
1. After repair orreplacementofparts,makesurethat thescrewsoftheoven, etc. areneither loosenor missing.
Microwavemightleakifscrewsarenotproperly tightened.
2. Makesurethatall electrical connections aretightbeforeinserting theplugintothewalloutlet.
3. Check for microwaveenergy leakage. (Refer toprocedurefor measuringmicrowaveenergy leakage).

IMPORTANTNOTICE
Thefollowingcomponents havepotentials above2000Vwhilethe applianceis operated.
lMagnetron
lHighvoltage transformer (Locatedoninverter(U))
lHighvoltage diodes (Located oninverter (U))
lHighvoltage capacitors (Locatedoninverter(U))
Pay specialattentiontotheseareas.
When theapplianceis operatedwiththedoorhinges ormagnetroninstalledincorrectly, themicrowaveleakagecan
exceedmorethan5mW/cm 2 .Afterrepair or exchange,itis very importanttocheck ifthemagnetron andthe door
hingesarecorrectly installed.

1. MountthePrimary latchswitch,theSecondary latchswitchand theshort switchtothedoor hook assembly as
showninILL.
NOTE:

orShortswitchtothedoorhookarerequired.
2. When mountingthedoor hook assembly totheovenassembly, adjust thedoor hook assembly by movingitinthe
direction ofthe arrows intheillustrationsothattheovendoorwillnot haveany play init. Check forplay inthedoor
by pullingthe door assembly.Makesurethat thelatchkeys movesmoothly after adjustmentis completed.

4.2Measurementofmicrowaveoutput
Theoutputpower ofthemagnetroncanbedeterminedby performingIEC standardtest procedures. However,due to
thecomplexity of IECtestprocedures, it isrecommendedtotestthemagnetronusingthesimplemethodoutlined
below.
Necessary Equipment:
*1 literbeaker *Glass thermometer
*Wristwatchor stopwatch
NOTE:
Checkthelinevoltageunderload.Lowvoltagewilllowerthemagnetronoutput. Takethetemperaturereadings
andheatingtime asaccuratelyaspossible.
1. Fill thebeakerwithexactlyoneliter oftapwater.Stir thewaterusingthethermometer andrecordthewater’s
temperature. (recordedasT1).
2. Placethebeaker onthecenterofglass tray.
SettheovenforHighpower andheatit for exactly oneminute.
3. Stirthewater againandreadthetemperatureof thewater.(recordedas T2).
4. Thenormal temperatureriseatHighpower level for eachmodel, is as shownintable.
