WARNiNG TO SERviCE PERSONNEL
Microwave ovens contain circuitry capable of pro-
ducing very high voltage and current, contact with
following parts
may result in a severe, possibly
fatal, electrical shock.
(Example)
Inverter unit that includes High Voltage Capacitor,
High Voltage Power Transformer, High Voltage
Rectifier, Heat sink etc., and Magnetron, High
Voltage Harness etc..
Read the Service Manual carefully and follow all
instructions.
Before Servicing
1. Disconnect the power supply cord
, and then
remove outer case.
2. Open the door and block it open.
3. Wait for 60 seconds to discharge the high voltage capacitors
of the inverter unit.
4. Disconnect the high voltage wire from the magnetron
terminal with insulated pliers.
5. Make the terminal (metal part) of the high voltage wire
contact to the magnetron body with insulated pliers.
6. Now, the capacitors of the inverter unit are discharged.
7. Reconnect the high voltage wire to the magnetron terminal
after discharging.
WARNiNG: Use the pliers that the portions of their
handles are insulated completely to avoid
an electric shock.
WARNiNG: RiSK OF ELECTRiC SHOCK.
After repairing
1. Reconnect all leads removed from components during
testing.
2. Reinstall the outer case (cabinet) and the back plate
assembly.
3. Reconnect the power supply cord after the outer case
and the back plate assembly are installed.
4. Run the oven and check all functions.
Microwave ovens should not be run empty. To test for the
presence of microwave energy within a cavity, place a cup
of cold water on the oven turntable, close the door and set
the power to HIGH and set the microwave timer for two
(2) minutes. When the two minutes has elapsed (timer at
zero) carefully check that the water is now hot. If the water
remains cold carry out “
Before Servicing”
procedure and
re-examine the connections to the component being tested.
When all service work is completed and the oven is fully
assembled, the microwave power output should be checked
and microwave leakage test should be carried out.
SERviCiNG FOR iNvERTER UNiT
WARNiNG
This inverter unit contains circuitry capable of produc-
ing high voltage and high current. Contact with any
part of the high voltage will result in electrocution.
DO NOT ACCESS ANY PARTS OF INVERTER UNIT
WITH POWER SUPPLY CONNECTED.
DO NOT OPERATE INVERTER UNIT ITSELF.
It is dangerous because this unit contains high volt-
age components.
Don't Touch !
Danger High voltage
