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. Disconnect the high voltage wire lead of the high voltage

rectifier assembly from the magnetron.

5. Disconnect the filament lead of the transformer from the

magnetron.

6. Remove the one (1) screw holding the magnetron duct

to the oven cavity top plate.

MAGNETRON REMOVAL

7. Remove the magnetron duct from the oven cavity, by

releasing the tab of the magnetron duct from the oven

cavity top plate.

8. Carefully remove four (4) mounting screws holding the

magnetron to waveguide. When removing the screws

hold the magnetron to prevent it from falling.

9. 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.

HIGH VOLTAGE RECTIFIER AND HIGH VOLTAGE CAPACITOR REMOVAL

cabinet) to the top cabinet.

5. While supporting the front of the oven, pull down the two

(2) mounting levers and release the oven from the unit

mounting plate.

6. Pull the power cord out of the wall cabinet and remove

OUTER CASE REMOVAL

Remove the oven from the wall, referring to "REMOVAL OF

OVEN FROM WALL" and proceed as follows;

1. Disconnect the power supply cord.

2. Open the door and block it open.

3. To discharge the high voltage capacitor, wait for 60

seconds.

4. Remove the four (4) screws from the rear of the outer

case cabinet and one (1) screw at right side.

5. Slide the outer case cabinet back about 1 inch (3 cm) to

free it from retaining clips on the cavity face plate.

6. Disconnect the three (3) pin connector of the power

supply cord from the wiring harness and remove the

power supply cord together with the outer case.

7. Nip the cord bushing with bushing pliers and release it

from the outer case cabinet.

8. Remove the cord bushing and the power supply cord

from the outer case cabinet.

9. Now, the power supply cord is free.

CAUTION: 1. DISCONNECT OVEN FROM POWER

SUPPLY BEFORE REMOVING OUTER

CASE.

2. DISCHARGE THE HIGH VOLTAGE

CAPACITOR BEFORE TOUCHING ANY

OVEN COMPONENTS OR WIRING.

POWER TRANSFORMER 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. To discharge the high voltage capacitor, wait for 60

seconds.

4. Disconnect main wire harness from transformer.

5. Disconnect high voltage wire A from the transformer.

6. Disconnect filament leads of transformer from the

magnetron and capacitor.

7. Remove two (2) screws holding the transformer to base

plate R.

Reinstall

1. Install by sliding the transformer on the base plate R with

its primary terminals toward the outer case.

2. Secure the transformer with two (2) screws to base plate

3. Reconnect 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. Reinstall the outer case and check that oven is operating

properly.

CAUTION: MAKE SURE THE WIRE LEADS NEVER

TOUCH THE FAN BLADE.

the oven.

7. The oven is now free and can be placed on the work

surface selected for servicing the oven.

8. Installation is the reverse of this procedure.

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. Disconnect the high voltage wire lead with high voltage

rectifier from the magnetron.

5. Disconnect filament lead of the transformer from high

voltage capacitor.
