High Voltage Rectifier And High
Voltage Capacitor Removal
1. Disconnect the power supply cord and then remove
outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect the high voltage wire leads with high
voltage rectifier from the magnetron.
5. Disconnect filament lead of the transformer from high
voltage capacitor.
6. Disconnect high voltage wire from capacitor.
7. Remove one (1) screw holding capacitor holder and
high voltage rectifier to the fan duct.
8. Disconnect the high voltage rectifier assembly from
the high voltage capacitor and remove one (1) screw
holding the voltage rectifier assembly to the capacitor
holder.
9. Now, the high voltage rectifier assembly is free.
10. Remove capacitor from the holder.
11. Now, the high voltage capacitor is free.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.
When replacing high voltage rectifier and high
voltage capacitor, ground side terminal of the high
voltage rectifier must be secured firmly with a
grounding screw.
Magnetron Removal
1. Disconnect the power supply cord and then remove
outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Remove two (2) screws holding the chassis support
right to the rear and face of the oven cavity flanges.
5. Remove the one (1) screw holding the noise filter
assembly to the fan duct.
6. Disconnect the wire leads from the fan motor.
7. Disconnect the high voltage wire leads of the high
voltage rectifier assembly from the magnetron.
8. Disconnect the filament lead of the transformer from
the magnetron.
9. Remove the one (1) screw holding the hood duct to
the fan duct and remove the one (1) screw holding
the oven cavity top plate to the fan duct.
10. Remove the one (1) screw holding the right base
plate to the fan duct and remove the fan duct
assembly.
11. Remove the power transformer from the right base
plate, referring to “Power Transformer Removal“.
12. Carefully remove four (4) mounting screws holding
the magnetron to waveguide. When removing the
screws hold the magnetron to prevent it from falling.
13. Remove the magnetron from the unit with care so the
magnetron tube should not be hit by any metal object
around the tube.
When replacing the magnetron, be sure the R.F.
Anode Gasket is in place and mounting screws are
tightened securely.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.
