Remove the fan duct assembly from the oven. 13.Remove one (1) screw holding the thermal cut-out mounting angle (with thermal cut-out) to the fan motor. 14.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 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 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. 15.Remove the two(2) screws holding the fan motor to the fan duct. 16.Now, the fan motor is free.

INSTALLATION 1. Re-install the thermal cut-out mounting angle (with thermal cut-out) to the fan motor with one (1) screw. 2. Install the fan motor to the fan duct with the two(2) screws. 3. Install the fan blade to the fan motor shaft according the following procedure. 1) Hold the center 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. 4. Reset the fan duct assembly to its place. 5. Install the fan duct to the waveguide with the two (2) screws. 6. Install the fan duct to the oven cavity front face plate with the one (1) screw. 7. Re-install the main harness and the thermistor harness to each hole of the fan duct. 8. Re-install the chassis support to the oven cavity front face plate, magnetron and the rear cabinet with the three (3) screws. 9. Re-install two snap bands of the thermistor harness to the chassis support. 10.Hold the main wire harness with the wire holder. 11.Re-connect the wire leads to the fan motor, thermal cutout (FAN) and the damper motor, referring to the pictorial diagram.
