6.1. Magnetron
1. Discharge the high voltage capacitor.
2. Remove 1 screw holding front plate bracket on cavity top
plate.
3. Remove 2 screws holding air guide A on cavity top plate

4. Remove 1 screw holding air guide A on the wave guide,
then remove the air guide A.
5. Remove 1 screw holding thermistor on the magnetron.
6. Remove 2 screws holding the magnetron.
NOTE:
After replacement of the magnetron,tighten mounting
screws properly, making sure there is no gap between
