1. CARRY OUT 3D CHECKS.
2. Disconnect the wire leads from the fan motor, thermal
cut-out (FAN) and magnetron.
3. Remove two (2) screws holding the chassis support to
oven cavity front plate and magnetron. And remove
chassis support.
4. Remove two (2) screws holding the magnetron to
waveguide flange. And remove the magnetron.
5. Remove one (1) screw holding the fan duct assembly to
oven cavity.
6. Release the fan duct assembly from the oven cavity.
7. Remove one (1) screw holding the thermal cut-out angle
to the fan motor.
8. Remove the fan blade from the fan motor shaft according
the following procedure.
1) Hold the edge of the rotor of the fan motor by using a pair
of grove 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 injured.
* Do not disfigure the bracket by touching with the
pliers.
2) Remove the fan blade from the shaft of the fan motor by
pulling and rotating the fan blade with your hand.
3) Now, the fan blade will be free.
CAUTION:
* Do not use this removed fan blade again because the
hole (for shaft) of it may become bigger than a
standard one.

9. Remove the two (2) screws holding the fan motor to the
fan duct.
10.Now, the fan motor is free.
INSTALLATION
1. Install the fan motor to the fan duct with the two (2)
screws.
2. Install the fan blade to the fan motor shaft according the
following procedure.
1) Hold the centre of the bracket which supports the shaft
of the fan motor on the flat table.
2) Apply the screw lock tight into the hole (for shaft) of the
fan blade.
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.
CAUTION:
* Do not hit the fan blade strongly when installed
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.
3. Install the thermal cut-out angle to the fan motor with one
(1) screw.
4. Catch two holes of fan duct on two tabs of the waveguide
flange.
5. Install the fan duct assembly to the oven cavity with the
one (1) screw.
6. Install the magnetron to waveguide flange with two (2)
screws.
7. Install one (1) tab of the chassis support to oven cavity
front plate and install another tab of it to rear plate. And
then screw chassis support to oven cavity front plate and
magnetron with two (2) screws.
8. Connect the wire leads to the fan motor, magnetron and
thermal cut-out (FAN), referring to the pictorial diagram.
