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.

2. CONvECTiON HEATER REMOvAL
1. Remove the convection unit from oven the cavity
assembly, referring to "CONVECTION UNIT REMOVAL".
2. Remove the two (2) screws holding the convection
heater to con- vection duct.
3. CONvECTiON MOTOR REMOvAL
1. Remove the convection unit from oven the cavity
assembly, referring to "CONVECTION UNIT REMOVAL".
2. Remove the convection cover angle B from the
convection cover. (Release the tab and remove the one
(1) mounting screw)
3. Remove the convection cover angle C from the
convection cover. (Release the tab and remove the
one (1) mounting screw)
4. Remove the fan blade from the convection motor shaft
by removing the one (1) nut, three (3) washer and one
(1) spacer.
DC FAN MOTOR (ventilation) REMOvAL
CONvECTiON UNiT ASSEMBLY
8. Remove the outer case cabinet, referring to
"OUTER CASE REMOVAL".
9. Remove the back plate, referring to "BACK PLATE
REMOVAL".
10.Remove the latch hook right, referring to "DOOR
SENSING SWITCH, 3RD DOOR SWITCH, SECOND
ARY INTERLOCK SWITCH AND MONITOR SWITCH
REPLACEMENT"
11. 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.
12.Remove the two (2) screws holding the DC fan motor to
the heat cover right assembly.
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
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.
5. Remove the convection motor mounting angle from the
convection cover by removing the two (2) screws.
6. Remove the convection motor from the convection
mounting angle by removing the two (2) screws.
7. 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 rotation of the cooling fan.
8. Now, the convection motor is free
