High Voltage Rectifier Removal
1. Disconnect the oven power supply cord and remove
outer case.
2. Discharge high voltage capacitor.
3. Remove one (1) screw holding the rectifier assembly
to the capacitor holder.
4. Disconnect the rectifier assembly from the capacitor
and magnetron.
High Voltage Capacitor Removal
1. Disconnect the oven power supply cord and remove
outer case.
2. Discharge high voltage capacitor.
3. Disconnect high voltage wire leads and rectifier
assembly from high voltage capacitor and
magnetron.
4. Disconnect filament lead of transformer from high
voltage capacitor.
5. Disconnect high voltage wire lead of capacitor from
transformer.
6. Remove one (1) screw and washer holding rectifier
from the capacitor holder.
7. Remove one (1) screw holding the capacitor holder
to the rear cabinet.
8. Remove the capacitor from the holder.
When replacing the silicon rectifier assembly, the
ground side terminal 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.

Turntable Motor/Coupling Removal
1. Disconnect the power supply cord.
2. Remove the turntable tray, and the turntable support
out of the oven cavity.
3. Turn the oven on its back and remove the screws
holding the bottom duct to bottom of the oven.
4. Remove the one (1) screw holding the turntable
motor cover to the base plate and take off the
turntable motor cover.
5. Disconnect wire leads from the turntable motor.
6. Remove the two (2) screws holding the turntable
motor.
7. Remove turn table motor, and if replacing coupling,
push coupling through the hole into inside the cavity.
Oven Lamp and Lamp Socket
Removal
1. Disconnect oven from power supply and remove
outer case.
2. Discharge high voltage capacitor.
3. Unplug wires from the lamp socket.
4. Remove lamp from socket.
5. Twist the lamp socket to free it from the holder.
6. Pull lamp socket through hole. The oven lamp socket
is now 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.
