Power Transformer Removal
1. Disconnect power supply cord and remove outer
case.
2. Open the oven door and block it open.
3. Discharge the high voltage capacitor.
4. Remove the back plate from the oven.
5. Disconnect the main wire harness from the power
transformer.
6. Disconnect the high voltage wire and filament leads
of the power transformer from the high voltage
capacitor and the magnetron.
7. From under the bottom plate, remove the two (2)
screws securing the transformer mounting angle to
the bottom plate.
8. From the top of the bottom plate, remove the two (2)
screws securing the transformer mounting angle to
the bottom plate.
9. Remove the four (4) screws holding the power
transformer to the transformer mounting angle.
10. Now, the power transformer is free.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.
Reinstall
1. Reinstall the cord bushing to the power supply cord.
2. Insert the power supply cord with the cord bushing
into the hole of the back plate.
3. Secure the green wire of the power supply cord to the
bottom plate with the one (1) screw.
4. Reconnect the black wire of the power supply cord to
the fuse holder, referring to the pictorial diagram.
5. Reconnect the white wire of the power supply cord
to the main wire harness, referring to the pictorial

3. Discharge the high voltage capacitor.
4. Remove the one (1) screw securing the green wire of
the power supply cord to the bottom plate.
5. Disconnect the black wire of the power supply cord
from the fuse holder, and the white wire from the
main wire harness.
6. Remove the three (3) screws securing the back plate
to the bottom plate.
7. Remove the two (2) screws holding the right and left
chassis supports to the back plate.
8. Release the tabs of the chassis supports from the
back plate.
9. Now, the back plate is free.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.
