F. AIR DUCT ASSEMBLY REMOVAL
1) Disconnect the leadwire from lamp and MGT thermostat.
2) Remove the mounting screw to the magnetron.
G. MAGNETRON REMOVAL
1) Disconnect the leadwire from the magnetron.
2) Carefully remove the mounting screws holding the
magnetron and the waveguide.
3) Remove the magnetron Ass’y until the tube is clear
from the waveguide.
NOTE:
1. When removing the magnetron, make sure its dome
does not hit any adjacent parts, or it may be damaged.
2. When replacing the magnetron, be sure to install
the magnetron gasket in the correct position and be
sure that the gasket is in good condition.
3. After replacing the magnetron, check for microwave
leakage with a survey meter around the magnetron.
Microwave energy must be below the limit of 5
mW/cm
2
. (With a 275 ml. water load).
Make sure that gasket is rigidly attached to the
magnetron.
To prevent microwave leakage, tighten
the mounting screws properly, making sure there is
no gap between the waveguide and the magnetron.
H. HIGH VOLTAGE TRANSFORMER
REMOVAL
1) Discharge the high voltage capacitor.
2) Disconnect the leadwire from magnetron, high voltage
transformer, and capacitor.
3) Remove the screw holding the high voltage
transformer to the base-plate.
I. FAN MOTOR ASSEMBLY REMOVAL
1) Discharge the high voltage capacitor.
2) Disconnect the leadwire from fan motor, noise filter
and high voltage capacitor.
3) Remove the two screws holding the suction guide
Ass’y to the oven cavity and remove the high voltage
diode earth screw.
4) Remove the screw of the capacitor bracket.
5) Remove the two screws holding the fan motor Ass’y to
the suction guide Ass’y.
J. HIGH VOLTAGE CAPACITOR AND
DIODE REMOVAL
1) Discharge the high voltage capacitor.
2) Disconnect the leadwire from the fan motor, noise
filter and high voltage capacitor.
3) Remove the screw holding the suction guide Ass’y to
the oven cavity and remove the high voltage diode
earth screw.
4) Remove the screw holding the high voltage capacitor
bracket.
