4. Disassembly and Reassembly
4-1 Replacement of Magnetron, Motor Assembly and Lamp
Remove the magnetron including the shield case,
permanent magnet, choke coils and capacitors (all
of which are contained in one assembly).
1. Disconnect all lead wires from the magnetron
and lamp.
2. Remove the bracket mounting.
3. Remove the magnetron supporter.
4. Remove the air cover.
5. Remove screws securing the magnetron to the
wave guide.
6. Take out the magnetron very carefully.
7. Remove screws from the back panel.
8. Take out the fan motor.
9. Remove the oven lamp by rotating to pull out from
hole of air cover.
NOTE1: When removing the magnetron, make sure that its antenna does not hit any adjacent parts, or it
may be damaged.
NOTE2: When replacing the magnetron, be sure to remount the magnetron gasket inthe correct position and
make sure the gasket is in good
4-2 Replacement of High Voltage Transformer
1. Discharge the high voltage capacitor.
2. Disconnect all the leads.
3. Remove the mounting bolts.
4. Reconnect the leads correctly and firmly.
PRECAUTION
Servicemen should remove their watches
whenever
working close to or replacing the magnetron.
PRECAUTION
There exists HIGH VOLTAGE ELECTRICITY with
high current capabilities in the circuits of the
HIGH VOLTAGE TRANSFORMER secondary
and filament terminals. It is extremely dangerous
to work on or near these circuits with the oven
energized.
DO NOT measure the voltage in the high voltage
circuit including filament voltage of magnetron.
