Magnetron Removal
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 wire leads from magnetron.
5. Remove the two (2) screws holding the chassis
support to the magnetron and the oven cavity front
flange.
6. Slide the magnetron duct slightly so that the two (2)
screws at left hand side of the magnetron appear.
7. Carefully remove the four (4) screws holding
magnetron to waveguide flange.
8. Remove the magnetron with care so that the
magnetron antenna is not hit by any metal object
around the antenna.
9. Now, the magnetron is free.
Re-Install
1. Re-install the magnetron to waveguide flange with
care to prevent damage to the magnetron antenna.
2. Secure the magnetron with the four (4) screws.
3. Hold the chassis support to the oven cavity front plate
and the magnetron with the two (2) screws.
4. Reconnect the wire leads to the magnetron. Refer to
Wiring
Diagram.
5. Re-install outer case and check that the oven is
operating properly.
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 A from the high
voltage capacitor. See Wiring Diagram.
5. Disconnect the high voltage wire of high voltage
rectifier assembly from the magnetron.
6. Disconnect the filament lead (short one) of the power
transformer from the high voltage capacitor.
7. Remove one (1) screw holding capacitor holder with
the high voltage rectifier to the base plate.
8. Disconnect rectifier terminal from capacitor.
High voltage rectifier assembly is now free.
9. Remove capacitor holder. Capacitor is now free.
When replacing the magnetron, be sure the R.F.
Gasket is in place and mounting screws are
tightened securely.
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.
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.
