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).

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.
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.
Servicemen should remove their watches whenever
working close to or replacing the magnetron.
