Power Transformer Removal

REMOVAL
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".) And proceed as follows.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
NOTE
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.
4. Remove three (3) screws holding the base plate to
the oven cavity on the bottom , disconnect the wires
from turntable motor and two cooktop lamps. And
remove the base plate.
5. Disconnect main wire harness from transformer.
6. Disconnect high voltage wire from the transformer.
7. Disconnect filament leads of transformer from the
magnetron and capacitor.
8. Remove four (4) screws holding the transformer to
bottom plate.
RE-INSTALL
1. Install by sliding the transformer on the bottom plate
with its primary terminals toward the control panel.
2. Secure the transformer with four (4) screws to
bottom plate.
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 base plate on the bottom of cavity,
reconnect wire leads to the turntable motor and two
cooktop lamps. Re-install the base plate to the cavity
with four (4) screws.
5. Re-install the outer case and check that oven is
operating properly.
CAUTION
Make sure the wire leads never touch the fan
blade.

Hood Fan Motor 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. Discharge high voltage capacitor.
NOTE
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.
4. Disconnect the 6-pin connector of the hood fan
motor from the main wire harness located at the
right edge of the hood duct and release the snap
band from the hood duct. Remove one (1) screw
holding the hood fan motor on the rear cavity.
5. Remove the hood fan motor from the oven cavity
top plate by lifting it up.
