6. To remove high voltage capacitor. 

1) Remove the screw which secure the grounding ring

terminal of the H.V. diode and the capacitor holder.

2) Remove the H.V. diode from the capacitor holder.
3) Reverse the above steps for reassembly.

7. To remove magnetron.

1) Remove the screw which secure the magnetron.
2) Remove the magnetron.
3) Reverse the above steps for reassembly.

NOTE : Never install the magnetron without the metallic gasket plate which is packed with each magnetron to

prevent microwave leakage. Whenever repair work is carried out on magnetron, check the microwave
leakage. It shall not exceed 4mW/cm

for a fully assembled oven with door normally closed.
