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
R.
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.
