1. Disconnect the power supply cord, remove the oven
from wall and remove outer case (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal".)
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
4. Remove the three (3) screws holding the hood intake duct
R to the oven cavity top plate, the oven cavity front flange
and the fan duct. And remove the hood intake duct R.
5. Remove the one (1) screw holding the hood duct R to the
oven cavity top plate. And remove the hood duct R.
6. Disconnect the wire leads from the fan motor.
7. Disconnect the high voltage wire lead with the high
voltage rectifier from the magnetron.
8. Disconnect the filament lead of the transformer from the
high voltage capacitor.
9. Disconnect the high voltage wire A from the capacitor.
10.Release the wire leads from the hole of the fan duct.
11.Remove two (2) screws holding the fan duct to oven
cavity top plate and the base plate R.
12. Remove the fan duct assembly from the oven cavity.
13.Remove the fan blade from the fan motor shaft according
the following procedure.
14.Hold the edge of the rotor of the fan motor by using a pair
of groove joint pliers.
CAUTION:
*
Make sure that any pieces do not enter the gap
between the rotor and the stator of the fan motor
because the rotor is easily shaven by pliers and
metal pieces may be produced.
*
Do not touch the pliers to the coil of the fan motor
because the coil may be cut or damaged.
*
Do not disfigure the bracket by touching with the
pliers.
TEMPERATURE FUSE (MAGNETRON) REMOVAL
1. Disconnect the power supply cord and remove the oven
from wall and remove outer case. (Refer to procedure of
"Removal of Oven from Wall" and "Outer case Removal")
2. Open the door and block it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
4. Remove the fan duct assembly from the oven cavity,
referring to the procedure of " COOLING FAN MOTOR
REMOVAL".
5. Disconnect the wire leads from the temperature fuse
(Magnetron).
6. Remove the one (1) screw holding the temperature fuse
(Magnetron) to the fan duct.
7. Now, the temperature fuse (Magnetron) is free.
COOLING FAN MOTOR REMOVAL
15.Remove the fan blade from the shaft of the fan motor by
pulling and rotating the fan blade with your hand.
16. Now, the fan blade will be free.
CAUTION:
*
Do not reuse the removed fan blade because the
hole (for shaft) may be larger than normal.
17.Remove the two (2) screws holding the fan motor to the
fan duct.
18.Now, the fan motor is free.
INSTALLATION
1. Install the fan blade to the fan motor shaft according to
the following procedure.
2. Hold the center of the bracket which supports the shaft
of the fan motor on the flat table.
3. Install the fan blade to the shaft of fan motor by pushing
the fan blade with a small, light weight, ball peen hammer
or rubber mallet.
4. Install the fan motor to the hood duct with the two (2) screws.
CAUTION:
*
Do not hit the fan blade with excesive force when
installing because the bracket may be disfigured.
*
Make sure that the fan blade rotates smooth after
installation.
*
Make sure that the axis of the shaft is not slanted.
5. Install the fan duct to the oven cavity top plate and base
plate R with the two (2) screws.
6. Reconnect the wire leads to the fan motor, magnetron
and high voltage capacitor, referring to the pictorial
diagram.
7. Re-install the wire leads to the hole of the fan duct.
8. Re-install the hood intake duct R to the oven cavity top
plate, the oven cavity front flange and the fan duct with
the three (3) screws.
9. Refer to procedure of "OUTER CASE REMOVAL". And
reverse their procedure. And re-install the outer case.
