1. Disconnect the power supply cord.
2. Remove the outer case cabinet, referring to “OUTER CASE
CABINET REMOVAL”.
3. Open the oven door and block it open.
4. Discharge the high voltage capacitor.
5. Remove the one (1) screw holding the green wire of the power
supply cord to the bottom plate.
6. Disconnect the black wire and the white wire of the power
supply cord from the noise filter.
BACK PLATE REMOVAL
7. Remove the two (2) screws holding the back plate to the
exhaust duct.
8. Remove the three (3) screws holding the back plate to the
bottom plate.
9. Remove the two (2) screws holding the right and left chassis
supports to the back plate.
10. Release the tabs of the chassis supports from the back plate.
11. Now, the back plate (with the power supply cord) is free.
1. Disconnect the power supply cord.
2. Remove the outer case cabinet, referring to “OUTER CASE
CABINET REMOVAL”.
3. Open the oven door and block it open.
4. Discharge the high voltage capacitor.
5. Remove the back plate from the oven, referring to “BACK
PLATE REMOVAL”.
6. Disconnect the main wire harness from the power transformer.
7. Disconnect the high voltage wire and filament leads of the
POWER TRANSFORMER REMOVAL
power transformer from the high voltage capacitor and the
magnetron.
8. Remove the four (4) screws holding the transformer mounting
angle to the bottom plate from under the bottom plate.
9. Slide the transformer mounting angle rightward.
10. Remove the four (4) screws holding the power transformer to
the transformer mounting angle.
11. Now, the power transformer is free.
1. Disconnect the power supply cord.
2. Remove the outer case cabinet, referring to “OUTER CASE
CABINET REMOVAL”.
3. Open the oven door and block it open.
4. Discharge the high voltage capacitor.
5. Remove the back plate from the oven, referring to “BACK
PLATE REMOVAL”.
6. Disconnect the high voltage wire of the high voltage rectifier
assembly from the magnetron.
7. Disconnect the filament wire of the power transformer from the
magnetron.
8. Remove the two (2) screws holding the magnetron guide to the
magnetron and remove it.
MAGNETRON REMOVAL
9. Release the main wire harness from the hole of the magnetron
separator and the hook of the fan motor.
10. Remove the three (3) screws holding the magnetron separator
to the bottom plate and the thermal cover back.
11. Remove the magnetron separator from the oven.
12. Carefully remove the four (4) screws holding the magnetron to
the waveguide. When removing the screws, hold the magnetron
to prevent it from falling.
13. 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 THE MAGN-
ETRON MOUNTING SCREWS ARE TIGHTENED
SECURELY.
1. Disconnect the power supply cord.
2. Remove the outer case cabinet, referring to “OUTER CASE
CABINET REMOVAL”.
3. Open the oven door and block it open.
4. Discharge the high voltage capacitor.
5. Remove the back plate from the oven, referring to “BACK
PLATE REMOVAL”.
6. Disconnect the high voltage wire of the high voltage rectifier
assembly from the magnetron.
7. Disconnect the high voltage wire and the filament lead of the
power transformer from the high voltage capacitor.
8. Remove the one (1) screw holding the capacitor holder to the
HIGH VOLTAGE CAPACITOR AND HIGH VOLTAGE RECTIFIER ASSEMBLY REMOVAL
fan motor mounting angle.
9. Remove the one (1) screw holding the high voltage rectifier
assembly to the capacitor holder.
10. Disconnect the high voltage rectifier assembly from the high
voltage capacitor.
11. Now, the high voltage rectifier assembly is free, and also the
high voltage capacitor is free.
CAUTION: WHEN REPLACING THE HIGH VOLTAGE RECTI-
FIER ASSEMBLY, THE GROUND SIDE TERMINAL
MUST BE SECURED FIRMLY WITH A GROUND-
ING SCREW.

4. Discharge the high voltage capacitor.
5. Remove the back plate from the oven, referring to “BACK
PLATE REMOVAL”.
6. Remove the one (1) screw holding the capacitor holder to the
fan motor mounting angle. And remove the capacitor holder
from the fan motor mounting angle.
7. Disconnect the wire leads from the fan motor.
8. Remove the four (4) screws holding the fan motor mounting
angle to the bottom plate and the thermal cover back.
