PROCEDURE
7.1. Magnetron
1. Discharge the high voltage capacitor.
2. Remove 1 screw holding air guide A & reinforce bracket.
3. Disconnect 2 high voltage lead wires from magnetron filament
terminals.
4. Remove 4 screws holding the magnetron.
NOTE:
After replacement of the magnetron,tighten mounting screws
properly in an X pattern, making sure there is no gap between the
waveguide and the magnetron to prevent microwave leakage.
CAUTION
When replacing the magnetron, be sure the
antenna gasket is in place.
CAUTION
When connecting 2 filament lead wires to the
magnetron terminals, be sure to connect the lead
wires in the correct position. The lead wire of high
volatge transformer should be connected to “F
terminal” and the lead wire from high voltage
capacitor should be connected to “FA terminal”.
7.2. Digital Programmer Circuit (DPC) and membrane key board.
NOTE:
Be sure to ground any static electric charge built up on your body
before handling the DPC.
