FAN MOTOR REMOVAL

1.Disconnect oven from power supply and remove outer case.

2.Discharge high voltage capacitor.

3.Disconnect the wire leads from the fan motor.

4.Remove one (1) screw holding the fan motor grounding wire to the air guide (Right).

5.Remove three (3) screws holding the chassis support to the rear cabinet, waveguide and control panel back plate.

6.Remove the chassis support from the oven.

7.Remove one (1) screw holding the magnetron air guide to the waveguide.

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.
