Cooling Fan Duct, Fan Blade and Fan Motor
Two screws mount the cooling fan to the back cover of
the oven cavity. The fan blade is inserted onto the fan
shaft and a small amount of Loc-tite is applied to help
hold the blade on the shaft. The tabs at the top and
right side of the fan duct fit into slots in the back cover
of the oven cavity to hold the duct in place over the fan
motor and fan blade.
Fan Duct -
To remove the fan duct, the cabinet case
must first be removed.
(Though it is not necessary, it is
recommended to also remove the chassis support.)
Then, push the fan wire leads from the slot in the fan
duct. Pull the magnetron wire leads from the clip in the
fan duct. Push the rear tabs of the fan duct out of the
slots in the back cover, while pulling the fan duct up.
Fan Blade -
To remove the fan blade, first follow the
steps listed above to remove the fan duct. After the
duct is removed, pull the fan blade from the shaft of the
fan motor.
NOTE:
Because Loc-tite is used to help hold the blade
to the motor shaft, it may be necessary to hold the edge
of the fan motor rotor with pliers while pulling and rotat-
ing the fan blade.
Cooling Fan Motor -
To remove the fan motor, first
follow the steps listed above to remove the fan duct.
After the duct is removed, disconnect the wire leads
from the fan motor. Extract the motor mounting screws
from the back of the unit and lift the motor out.
Magnetron Duct
At the top of the magnetron duct is a ridged channel
that hooks around the top flange of the oven cavity.
Another channel, to the right of the light socket mount-
ing hole, fits over the lower flange of the chassis sup-
port.
To remove the magnetron duct, the cabinet case, chas-
sis support and lamp socket must first be removed.
Then, rotate the magnetron duct counterclockwise to
unhook the top channel from the oven cavity.
Magnetron
The magnetron is attached to the mounting plate on the
right side of the oven cavity with four screws.
To remove the magnetron, the cabinet case, chassis
support and magnetron duct must first be removed.
Then, extract the four magnetron mounting screws and
pull the magnetron from the mounting plate.
