4. Disconnect wire leads from convection motor, thermal
cut-out and heater element.
5. Remove nine (9) screws holding heater duct to the oven
cavity.
6. Remove two (2) screws holding heater duct to base
cabinet. Release two (2) snap bands holding wire harness

8. Remove the magnetron air guide from the waveguide.
9. Disconnect wire leads from the fan motor.
10. Release the main harness from the hole of the fan duct.
11. Release the thermistor harness from the hole of the fan
duct.
12. Release one (1) tab holding the fan duct to the rear
cabinet.
13. Release one (1) tab holding the fan duct to the air guide
(Right).
14.Remove the fan duct assembly from the oven.
15.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.
HEATING ELEMENT REMOVAL
1. Remove two (2) screws holding heating element to
heater duct.
2. Loosen two (2) screws holding holders to heater duct
and take heating element out of heating element holders.
