4. Disconnect the 6-pin connector of the hood fan motor
from the main wire harness located at the right edge of
the oven cavity top plate and release the snap band from
the hood duct.
5. Remove the hood fan motor from the oven cavity top
plate by lifting it up.
6. Now, the hood fan motor is free.
1. Disconnect the power supply cord , remove the oven
from wall and remove outer case (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal".)
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
4. Remove the three (3) screws holding the hood intake duct
R to the oven cavity top plate, the oven cavity front flange
and the fan duct. And remove the hood intake duct R.
5. Disconnect the high voltage wire lead of the high
voltage rectifier assembly from the magnetron.
6. Disconnect the filament lead of the transformer from the
magnetron.
7. Remove the one (1) screw holding the hood duct R to the
oven cavity top plate. And remove the hood duct R from
MAGNETRON REMOVAL
the oven cavity top plate R.
8. Remove the magnetron duct from the oven cavity, by
releasing the tab of the magnetron duct from the oven
cavity top plate.
9. Carefully remove four (4) mounting screws holding the
magnetron to waveguide. When removing the screws
hold the magnetron to prevent it from falling.
10.Remove the magnetron from the unit with care so the
magnetron tube should not be 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. Disconnect the power supply cord , remove the oven
from wall and remove outer case (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal".)
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
4. Remove the three (3) screws holding the hood intake duct
R to the oven cavity top plate, the oven cavity front flange
and the fan duct. And remove the hood intake duct R.
5. Disconnect the high voltage wire lead with high voltage
rectifier from the magnetron.
6. Disconnect filament lead of the transformer from high
voltage capacitor.
7. Disconnect high voltage wire A from capacitor.
HIGH VOLTAGE RECTIFIER AND HIGH VOLTAGE CAPACITOR REMOVAL
8. Remove the fan duct assembly from the oven cavity,
referring to the procedure of "COOLING FAN MOTOR
REMOVAL"
9. Remove one (1) screw holding capacitor holder and high
voltage rectifier to the fan duct.
10.Disconnect the high voltage rectifier assembly from the
high voltage capacitor.
11.Now, the high voltage rectifier assembly is free.
12.Remove capacitor from the holder.
13.Now, the high voltage capacitor is free.
CAUTION: WHEN REPLACING THE HIGH VOLTAGE
RECTIFIER ASSEMBLY, THE GROUND SIDE
TERMINAL MUST BE SECURED FIRMLY
WITH A GROUNDING SCREW.
THERMAL CUT-OUT (CAVITY) REMOVAL
1. Disconnect the power supply cord and remove the oven
from wall and remove outer case. (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal")
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
1. Disconnect the power supply cord and remove the oven
from wall and remove outer case. (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal")
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
4. Remove the three (3) screws holding the hood intake duct
R to the oven cavity top plate, the oven cavity front flange
HOOD FAN THERMAL CUT-OUT REMOVAL
and the fan duct. And remove the hood intake duct R.
5. Disconnect the wire leads from the hood fan thermal
cut-out.
6. Remove one (1) screw holding the thermal cut-out to the
flange of base plate R (turntable motor side).
7. Remove the hood fan thermal cut-out from the base plate
R.
8. Now, the hood fan thermal cut-out is free.
4. Disconnect the wire leads from the thermal cut-out
(cavity).
5. Remove the thermal cut-out (cavity) from the holder at
the oven cavity bottom plate.
6. Now, the thermal cut-out (cavity) is free.
