1. Unplug the oven from power outlet and remove the oven
from wall and remove outer case. (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal")
2. Disconnect the 6-pin connector of the hood fan motor
from the main wire harness located at the right edge of
the hood exhaust duct.
3. Disconnect the connector CN-F from the control unit.
4. Remove three (3) screws holding the hood exhaust duct
to the oven cavity.
5. Remove two (2) screws holding the hood exhaust duct to
the exhaust duct.
6. Release the 6-pin connector and the 3-pin connector of
the main harness A from the hood exhaust duct.
7. Release the one (1) snap band of the main harness A
from the left edge of the hood exhaust duct.
8. Release the snap band of the wire cord of the hood fan
motor from the hood exhaust duct.
9. Remove the hood fan motor from the hood exhaust duct
by lifting it up.
10.Now, the hood fan motor is free.
11.Remove the hood exhaust duct from the oven cavity by
lifting it up
12.Screw the oven lamp off from the lamp socket.
13.Remove the lamp socket from the lamp angle of the top
duct by releasing the two (2) tabs of the oven lamp
socket.
14.Pull the wire leads from the oven lamp socket by pushing
the terminal hole of the oven lamp socket with the small
flat type screw driver.
15.Now, the oven lamp socket is free.
16.Release the one (1) snap band of the AH sensor assembly
from the oven cavity.
17.Release the one (1) tab of the top duct from the AH
sensor assembly.
18.Remove two (2) screws holding the AH sensor assembly
to the exhaust duct.
19.Now, the AH sensor assembly and the exhaust duct are
free.

transformer.
5. Disconnect wire leads from transformer.
6. Remove two (2) screws holding the transformer to base
plate right.
Re-install
1. Rest the transformer on the base plate right with its
primary terminals toward the control panel.
2. Secure the transformer with two (2) screws to base plate
right.
3. Re-connect wire leads (primary and high voltage) to the
transformer and filament leads of transformer to
magnetron and high voltage capacitor. Refer to
"PICTORIAL DIAGRAM".
4. Re-install the hood intake duct R, and the outer case and
check that oven is operating properly.
CAUTION: MAKE SURE THE WIRE LEADS NEVER
TOUCH THE FAN BLADE.
HOOD FAN MOTOR, HOOD EXHAUST DUCT, OVEN LAMP SOCKET AND AH. SENSOR REMOVAL
1. Unplug the oven from power outlet, remove the oven
from wall, remove outer case, remove the unit mounting
screw and hood intake duct R. (Refer to procedure of
"Removal of Oven from Wall", "Outer case Removal"
and "Unit Mounting Screw and Hood Intake Duct R
Removal".)
2. Discharge high voltage capacitor.
3. Remove the hood fan motor and the hood exhaust duct
from the oven cavity, referring to the procedure of
"HOOD FAN MOTOR, HOOD EXHAUST DUCT, OVEN
LAMP SOCKET AND AH SENSOR REMOVAL".
4. Disconnect the high voltage wire leads of the high
MAGNETRON REMOVAL
voltage rectifier assembly from the magnetron.
5. Disconnect the filament lead of the transformer from the
magnetron.
6. Carefully remove the four (4) mounting screws holding
the magnetron to waveguide. When removing the screws
hold the magnetron to prevent it from falling.
7. Remove the magnetron from the unit with care so the
magnetron tube should not hit by any metal object
around the tube.
CAUTION: WHEN REPLACING THE MAGNETRON, BE
SURE THE R.F. GASKET IS IN PLACE AND
MOUNTING SCREWS ARE TIGHTENED SE-
CURELY.
1. Unplug the oven from power outlet, remove the oven
from wall, remove outer case, remove the unit mounting
screw and hood intake duct R. (Refer to procedure of
"Removal of Oven from Wall", "Outer case Removal"
and "Unit Mounting Screw and Hood Intake Duct R
Removal".)
2. Discharge high voltage capacitor.
3. Disconnect the high voltage wire leads with high voltage
HIGH VOLTAGE RECTIFIER AND HIGH VOLTAGE CAPACITOR REMOVAL
rectifier from the magnetron.
4. Disconnect filament lead of the transformer from high
voltage capacitor.
5. Disconnect high voltage wire lead of capacitor from the
transformer.
6. Remove one (1) screw holding capacitor holder to the
back plate.
7. Remove one (1) screw holding high voltage rectifier from
the capacitor holder.
