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.
2. Remove a screw securing air cover.
3. Remove the air cover.
4. Remove screws securing the magnetron to the
wave guide.
5. Take out the magnetron very carefully.
6. Remove a screw securing Bracket MGT.
7. Remove the Bracket MGT.
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 in the
correct position and make sure the gasket
is in good condition.
4-2 Replacement of High Voltage Capacitor
1. Discharge the high voltage capacitor.
2. Disconnect all the leads.
3. Remove the screw.
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.
