E. DOOR GROSS ASSEMBLY REMOVAL
1) Open the door.
2) Remove the choke cover very carefully with a flat-
blade screwdriver.
CAUTION: Be careful not to damage door seal
plate by screwdriver.
3) Lift up and push the door.
NOTE:
1. After replacing the door, be sure to check that the
primary switch, monitor switch, and secondary
switch operate normally.
2. After replacing the door, check for microwave
energy leakage with a survey meter. Microwave
energy must be below the limit of 5 mW/cm. (with a
275 ml water load)
3. When mounting the door assembly to the oven
assembly, be sure to adjust the door assembly
parallel to the chassis. Also adjust so the door has
no play between the inner door surface and oven
frame assembly. If the door assembly is not
mounted properly, microwaves may leak from the
clearance between the door and the oven.
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 high voltage
transformer and high voltage capacitor.
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.
