7. Reconnect the high voltage wire to the magnetron terminal after
discharging.
WARNING: Use the pliers that the portions of their handles are
insulated completely to avoid an electric shock.
8. Remove the four (4) screws holding the side angle.
9. Remove the side angle.
10.Remove the two (2) screws holding the latch base angle.
11.Remove the latch base angle.
12.Remove the tube pump assembly, referring to “TUBE PUMP
ASSEMBLY REMOVAL”.
However, the tube pump assembly does not need to remove from
the tank cover.

[13] CONVECTION UNIT ASSEMBLY
1. CONVECTION UNIT 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.
7. Reconnect the high voltage wire to the magnetron terminal after
discharging.
WARNING: Use the pliers that the portions of their handles are
insulated completely to avoid an electric shock.
8. Remove the wire harness from the convection heater by removing
the two (2) screws.
9. Remove the wire harness from the convection motor.
10.Remove the two (2) screws holding the water proof angle to the
oven cavity.
11.Remove the ten (10) nuts holding the convection unit to the oven
cavity assembly.
12.Now, the convection unit is free
2. CONVECTION HEATER REMOVAL
1. Remove the convection unit from oven the cavity assembly, refer-
ring to “CONVECTION UNIT REMOVAL”.
2. Remove the two (2) screws holding the convection heater to con-
vection duct.
3. Remove the convection heater from the two (2) heater mounting
plates.
4. Remove the convection heater from the convection duct.
5. Now the convection heater is free.
3. CONVECTION MOTOR REMOVAL
1. Remove the convection unit from oven the cavity assembly, refer-
ring to “CONVECTION UNIT REMOVAL”.
2. Remove the duct divide plate from the convection cover.(Remove
the one (1) mounting screw.)
3. Remove the convection cover angle assembly from the convection
cover. (Release the tab and remove the one (1) mounting screw)
4. Remove the convection cover angle C from the convection cover.
(Release the tab and remove the one (1) mounting screw)
5. Remove the fan blade from the convection motor shaft by removing
the one (1) nut, three (3) washer and one (1) spacer.
6. Remove the convection motor mounting angle from the convection
cover by removing the two (2) screws.
7. Remove the convection motor from the convection mounting angle
by removing the two (2) screws.
8. Remove the one (1) ring from the convection motor shaft.
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.
9. Now, the convection motor is free
[14] MAGNETRON REPLACEMENT
1. REMOVAL

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.
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.
