2. CAUTIONS TO BE OBSERVED WHEN

TROUBLESHOOTING

Unlike manyotherappliances, the microwave ovenis a high voltage, high current device. It is

free fromdangerinordinaryuse, though extreme care shouldbe takenduring repair.

Caution

Servicemen shouldremove theirwatches whenever working close

to or replacing the magnetron.

2.1. Check the grounding

Donot operate on a twowire extension cord. The microwave ovenis designedtobe grounded

whenused. It is imperative, therefore, toensure the appliance is properlygroundedbefore

beginning repairwork.

2.2. Inverter warnings

DANGER, HIGH VOLTAGE AND HIGH TEMPERATURE (HOT/LINE) OFTHE INVERTER POWER

SUPPLY (U)

The high voltage inverter power supplyhandles veryhigh voltage

and current for the magnetron tube. Though itisfree from danger

inordinaryuse, extreme care shouldbe taken during repair.

The aluminum heat sink isalso energized with high voltage (HOT),

do not touch when the AC input terminalsare energized. The power

device Collector isdirectlyconnected to the aluminum heat sink.

The aluminum heat sink maybe HOTdue to heat energy, therefore,

extreme care shouldbe taken during servicing.

H.V. Inverterwarning

WARNING FOR INVERTER POWER SUPPLY (U) GROUNDING

Check the high voltage inverter power supplycircuitgrounding.

The high voltage inverter power supplycircuitboard must have a

proper chassisground. The inverter grounding bracket must be

connected to the chassis. Ifthe inverter board isnot grounded it

will expose the user to veryhigh voltages and cause extreme

DANGER!Besure that the inverter circuitisproperlygrounded via

the inverter earth bracket.

Grounding of the invertercircuit board

WARNING!DISCHARGE THE HIGH VOLATGE CAPACITORS

For about 30 seconds after the oven isturned off, an electriccharge

remains inthe high voltage capacitors inthe inverter power supply

circuitboard.

When replacing or checking parts, remove the power plug from the

outlet and short the inverter output terminal of the magnetron

filament terminalsto the chassisground with an insulated handle

screwdriver to discharge. Please be sure to touch the chassis

ground side first and then short to the output terminals.

Discharging the high voltage capacitors

WARNING

There ishigh voltage present with high current capabilities inthe

circuits of the primaryand secondarywindings, choke coil and heat

sink of the inverter. Itisextremelydangerous to work on or near

these circuits with the oven energized. DO NOTmeasure the

voltage inthe high voltage circuitincluding the filament voltage of

the magnetron.

WARNING

Never touch anycircuitwiring with your hand or with an insulated

tool during operation.

2.3. Part replacement.

Whenanypart orcomponent is tobe replaced, always ensure that the powercordis removed

fromthe wall outlet.

2.4. When the 10Afuse isblowndue to the operation of the short

switch:

WARNING

When the 10A250V fuse isblowndue to the operation of the

interlock monitor switch, replace all of the components (primary

latch switch, secondarylatch switch, short switch and power relay

B(RY1)).

1. Thisismandatory. Refer to “adjustments and measurements” for

the location of these switches.

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

for these models.

3. When replacing faultyswitches, be sure the mounting tabs are

not bent, broken or 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

holes 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 energyleakage).
