AX1500J(S)
NOTE: If the ring, when removed, has been deformed, replace it with
new one. Using any deformed ring causes unbalanced rota-
tion of the cooling fan.

[14] MAGNETRON REPLACEMENT

1. REMOVAL
1. Disconnect the power supply cord, and then remove the outer case
and the back plate assembly.
2. Open the door and block it open.
3. Wait for 60 seconds to discharge the high voltage capacitors of the
inverter unit.
4. Disconnect the high voltage wire from the magnetron terminal with
insulated pliers.
5. Make the terminal (metal part) of the high voltage wire contact to
the magnetron body with insulated pliers.
6. Now, the capacitors of the inverter unit are discharged.
WARNING: Use the pliers that the portions of their handles are
insulated completely to avoid an electric shock.
7. Remove the bottom plate, referring to "BOTTOM PLATE
REMOVAL".
8. Disconnect the wire leads from magnetron.
9. Remove the two (2) screws holding the bottom shield plate to the
oven cavity with the magnetron.

[15] SIROCCO MOTOR REMOVAL

1. Disconnect the power supply cord.
2. Wait for 60 seconds to discharge the high voltage capacitors of the
inverter unit.
3. Remove the outer case cabinet, referring to "OUTER CASE
REMOVAL".
4. Remove the one (1) screw fixing the sirocco motor to the steam
duct ORG.
5. Hold the left end of the sirocco motor and pull it toward you to
remove it from the steam duct.

[16] ANTENNA MOTOR REMOVAL

The antenna motor can be changed with the cabinet installed.
1. Disconnect the power supply cord.
2. Wait for 60 seconds to discharge the high voltage capacitors of the
inverter unit.
3. With the unit upside down, cut the six (6) ribs of the bottom plate so
as to partly cut off the bottom plate.

[17] POWER SUPPLY CORD REPLACEMENT

1. Removal
1. Disconnect the power supply cord, and then remove the outer case
and the back plate assembly.
2. Open the door and block it open.
3. Wait for 60 seconds to discharge the high voltage capacitors of the
inverter unit.
4. Disconnect the high voltage wire from the magnetron terminal with
insulated pliers.
8. Now, the convection motor is free
10.Remove the two (2) screws holding the magnetron to the
waveguide.
11. Remove the magnetron from waveguide.
12.Now, the magnetron is free.
2. REINSTALLTION
1. Reinstall the magnetron to waveguide flange with the two (2)
screws.
2. Reinstall the bottom shield plate with magnetron by the two (2)
screws.
3. Reinstall the bottom plate assembly to the oven with eleven (11)
screws.
4. Reconnect the wire leads to the magnetron, convection heater,
convection motor and thermal cut-outs.
5. Reinstall outer case and check that the oven is operating properly.
CAUTION: WHEN REPLACING THE MAGNETRON, BE SURE THE
R.F. GASKET IS IN PLACE AND THE MAGNETRON
MOUNTING SCREWS ARE TIGHTENED SECURELY.

4. Disconnect the terminal from the antenna motor.
5. Remove the two (2) antenna motor screws and remove the
antenna motor.
NOTE: When installing, install some cut parts by adding the two (2)
screws (XHTS740P08000).
5. Make the terminal (metal part) of the high voltage wire contact to
the magnetron body with insulated pliers.
6. Now, the capacitors of the inverter unit are discharged.
WARNING: Use the pliers that the portions of their handles are
insulated completely to avoid an electric shock.
7. Remove the bottom plate assembly, referring to "BOTTOM PLATE
