STIRRER MOTORS (UPPER AND LOWER) REMOVAL

1. CARRY OUT 3D CHECKS.
2. Remove the rear cabinet, too.
3. Disconnect the wire leads from the blower motor and

blower motor temperature fuse.

4. Remove the one (1) screw holding the blower motor to

the oven cavity.

5. Remove the one (1) screw holding the blower motor to

the chassis support.

UPPER
1. CARRY OUT 3D CHECKS.
2. Disconnect the wire leads from the stirrer motor (up-

per).

3. Remove the one (1) screw holding the stirrer motor

(upper) to the oven cavity.

4. Turn and lift up the stirrer motor (upper).
5. Now, the stirrer motor (upper) is free.

LOWER
1. Disconnect oven from the power supply.
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.)

HOW TO RELEASE THE POSITIVE LOCK

CONNECTOR.

Procedure
1. CARRY OUT 3D CHECKS.
2. Pushing the lever of positive lock

connector, pull down

the connector from the terminal.

3. Now, the connector is free.

CAUTION: WHEN CONNECTING THE POSITIVE

LOCK

CONNECTORS TO THE TERMI-

NALS, CONNECT THE POSITIVE LOCK

CONNECTOR SO THAT THE LEVER
FACES YOU.

Now, the the high voltage rectifier assembly is free.

8. Remove two (2) screws holding the capacitor holder to

oven cavity.
Now, the capacitors are free.

CAUTION:
1. DISCHARGE THE TWO HIGH VOLTAGE CAPACI-

TORS BEFORE TOUCHING ANY OVEN COMPO-
NENTS 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 RECTI-

FIER ASSEMBLY AND THE HIGH VOLTAGE CA-
PACITOR, THE CATHODE (EARTH) SIDE TERMI-
NAL OF THE HIGH VOLTAGE RECTIFIER MUST BE
SECURED FIRMLY WITH A EARTHING SCREW.

BLOWER MOTOR AND BLOWER MOTOR TEMPERATURE FUSE REMOVAL

6. Remove the one (1) screw holding the air duct to the

blower motor.

7. Remove the blower motor from the oven cavity.
8. Remove the two (2) screws holding the blower motor

temperature fuse to the blower motor.

9. Now, the blower motor and blower motor temperature

fuse are free.
