POWER TRANSFORMER REMOVAL
Reinstallation
1. Rest transformer on the base plate with its primary
terminals toward the left side.
2. Secure transformer with four screws to base plate.
3. Re-connect wire leads (primary and high voltage) to
power transformer and filament leads of transformer to
magnetron and high voltage capacitor. Refer to
"PICTORIAL DIAGRAM".
4. Reinstall the oven cavity assembly to the base plate.
Refer to "OVEN CAVITY ASSEMBLY REMOVAL".
5. Re-install outer case and check that oven is operating
properly.
1. Disconnect the power supply cord and then remove
outer case.
2. Remove the oven cavity assembly from the base plate.
Refer to "OVEN CAVITY ASSEMBLY REMOVAL".
3. Discharge the high voltage capacitor.
4. Disconnect the wire leads (primary and high voltage)
from power transformer and the filament leads from the
magnetron and capacitor terminals.
5. Remove four (4) screws holding transformer to base
plate.
6. Remove transformer from base plate.
1. Disconnect the power supply cord and then remove
outer case.
2. Remove the oven cavity assembly from the base plate.
Refer to "OVEN CAVITY ASSEMBLY REMOVAL".
HIGH VOLTAGE RECTIFIER AND HIGH VOLTAGE CAPACITOR REMOVAL
7. Lift entire outer case from the unit.
CAUTION: 1. DISCONNECT OVEN FROM POWER SUP
PLY BEFORE REMOVING OUTER CASE.
2. DISCHARGE THE HIGH VOLTAGE CA-
PACITOR BEFORE TOUCHING ANY OVEN
COMPONENTS OR WIRING.
NOTE: When replacing the outer case, the 2 special
Torx screws must be reinstalled in the same
locations.
Before removal of the power transformer, high voltage
capacitor, high voltage rectifire, magnetron, fan motor and
turntable motor, the oven cavity must be removed from base
plate as follows.
Removal
1. Disconnect the power supply cord and then remove
outer case (refer to "OUTER CASE REMOVAL").
2. Open the oven door and block it open.
3. It is recommended that the door is removed from the
oven cavity. Refer to "DOOR REPLACEMENT".
4. Disconnect the wire leads from the power supply cord,
power unit, turntable motor, thermal cut-out (oven),
thermal cut-out (MG.), all switches on the latch hook and
the magnetron.
5. Release the two (2) snap bands of the main wire harness
from the oven cavity.
6. Remove the lamp socket from the lamp angle. Refer to
"OVEN LAMP AND LAMP SOCKET REMOVAL".
7. Remove the two (2) screws holding the front leg to the
oven cavity.
8. Remove the front leg from the oven cavity by releasing
the three (3) tabs.
9. Remove the two (2) screws holding the waveguide
flange of the oven cavity to the base plate.
10.Remove the three (3) screws holding the base plate to
the oven cavity front plate.
11.Remove the three (3) screws holding the base plate to
the oven cavity back plate.
12.Lift up the oven cavity assembly and remove it from the
base plate.
13.Now the power transformer, high voltage capacitor, high
voltage rectifier and fan motor can be found on the base
OVEN CAVITY ASSEMBLY REMOVAL
plate.
14.The magnetron can be found at wavegide flange of the
oven cavity.
15. The turntable motor can be found under the oven cavity
bottom plate.
Reinstallation
1. Make sure that the electrical parts on the base plate are
reinstalled at their positions.
2. Make sure that the wire leads are reconnected to their
correct positions. Refer to the "PICTORIAL DIAGRAM".
3. Reinstall the oven cavity assembly on the base plate.
4. Hold the base plate to the oven cavity back plate with
three (3) screws.
5. Hold the base plate to the oven cavity front plate with
three (3) screws.
6. Hold the waveguide flane of the oven cavity to the base
plate with two (2) screws.
7. Reinstall the front leg to the oven cavity front plate.
8. Hold the front leg to the oven cavity front plate with two
(2) screws.
9. Reinstall the lamp socket to the lamp angle. Refer to
procedures of "OVEN LAMP AND LAMP SOCKET
REMOVAL".
10.Insert the two (2) snap bands of main wire harness to the
two (2) holes of oven cavity.
11. Reconnect the wire leads to the magnetron, all switches,
thermal cut-out (MG.), thermal cut-out (oven.), lamp
socket, turntable motor and power supply cord. Refer to
the "PICTORIAL DIAGRAM" on page 32.
12. If the door has been removed, reinstall the door to the
oven cavity. Refer to "DOOR REPLACEMENT".
13. Now, the oven cavity assembly should be reinstalled.
