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.
PRECAUTION
Never touch any circuit wiring with your hand nor with an
insulated tool during operation.
1. Discharge the high voltage capacitor.
2. Disconnect all the leads from the high voltage transformer.
3. Remove the mounting bolts on the high voltage transformer.
4. When replacing, connect the leads correctly and firmly.
NOTE 1 : When removing the magnetron, make sure that its antenna does not hit any adjacent parts, or it
may be damaged.
NOTE 2 : When replacing the magnetron, be sure to remount the magnetron gasket in the correct position
and make sure the gasket is in good condition.
