1. Disconnect the power supply cord and then remove outer
case and rear cabinet , referring to "OUTER CASE, REAR
CABINET AND POWER SUPPLY CORD REMOVAL".
2. Open the oven door and block it open.
3. Discharge two high voltage capacitors.
4. Remove two (2) screws holding ground side terminals of
high voltage rectifier assembly to the capacitor holder and
oven cavity.
5. Disconnect all wire leads from the high voltage capacitor.
6. Disconnect wire leads of high voltage rectifier assembly
from the power transformers (1) and/or (2).
Now, high voltage assembly is free.
7. Remove the three (3) screws holding the blower motor to
the top of oven cavity, the chassis support and air duct.
8. Remove two (2) screws holding the capacitor holder to
oven cavity.
HIGH VOLTAGE CAPACITOR AND HIGH VOLTAGE RECTIFIER ASSEMBLY REMOVAL
Now, the capacitors (1), (2) and the high voltage rectifier
assembly are free.
CAUTION:
1. DISCHARGE THE TWO HIGH VOLTAGE CAPACITOR
BEFORE TOUCHING ANY OVEN COMPONENTS OR
WIRING.
2. DO NOT REPLACE ONLY THE HIGH VOLTAGE
RECTIFIER. IF IT IS DEFECTIVE, REPLACE THE HIGH
VOLTAGE RECTIFIER ASSEMBLY.
3. WHEN REPLACING THE HIGH VOLTAGE RECTIFIER
ASSEMBLY AND THE HIGH VOLTAGE CAPACITOR,
THE GROUND SIDE TERMINAL OF THE HIGH VOLTAGE
RECTIFIER MUST BE SECURED FIRMLY WITH A
GROUNDING SCREW.
Procedure
1. Disconnect the power supply cord and then remove outer
case and rear cabinet, referring to "OUTER CASE, REAR
CABINET AND POWER SUPPLY CORD REMOVAL".
2. Open the oven door and block it open.
3. Discharge two high voltage capacitors.
4. Pushing the lever of positive lock
®
connector, pull down the
connector from the terminal.
5. Now, the connector is free.
Note:
If the positive lock
®
has a insulation sleeve, first
remove it. If you do not, you can not push the lever
of positive lock
®
.
CAUTION: THE POSITIVE LOCK
®
TERMINAL CAN NOT BE
REMOVED BYJUST PULLING ON IT. THE LOCK
LEVER MUST BE RELEASED TO REMOVE THE
CONNECTOR FROM THE TERMINAL.
HOW TO RELEASE THE POSITIVE LOCK

CONNECTOR.
Figure C-2. How to release the positive lock connector.
1. Disconnect the power supply cord and then remove outer
case and rear cabinet, referring to "OUTER CASE, REAR
CABINET AND POWER SUPPLY CORD REMOVAL".
2. Open the oven door and block it open.
3. Discharge two high voltage capacitors.
4. Disconnect the main wire harness from the blower motor
and noise filter.
5. Remove the two (2) screws holding the blower motor angle
BLOWER MOTOR REMOVAL
to the oven cavity.
6. Remove the one (1) screw holding the blower motor angle
to the chassis support.
7. Remove the blower motor from the oven cavity.
8. Remove the two (2) screws holding the noise filter angle to
the blower motor.
9. Now, the blower motor is free.

STIRRER MOTORS (UPPER AND LOWER) REMOVAL
UPPER
1. Disconnect the power supply cord and then remove outer
case, referring to "OUTER CASE, REAR CABINET AND
POWER SUPPLY CORD REMOVAL".
2. Open the oven door and block it open.
3. Discharge two high voltage capacitors.
4. Disconnect the wire leads from the stirrer motor (upper).
5. Remove the one (1) screw holding the stirrer motor (upper)
to the oven cavity.
6. Turn and lift up the stirrer motor (upper).
7. Now, the stirrer motor (upper) is free.
LOWER
1. Disconnect the power supply coed.
2. Remove the stirrer motor cover by snipping off the material
in four portions.
3. Where the portions have been snipped off bend the portions
flat. No sharp edge must be evident after removal of the
stirrer motor cover.
4. Disconnect the wire leads from the stirrer motor (lower).
5. Remove the one (1) screw holding the stirrer motor (Lower)
to the oven cavity.
6. Now, the stirrer motor (lower) is free.
7. After replacement use one (1) screw to fit the stirrer motor
cover. (This screw has been fitted to the base plate near the
stirrer motor cover beforehand.)
