D. DOOR ASSEMBLY / REMOVAL
1) Disconnect power.
2) Open the door from oven. insert "JIG" into the choke
cover hole of door.
3) Lift the door from front cavity.
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
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.

E. HIGH VOLTAGE TRANSFORMER
REMOVAL (Refer to page 5-5)
1) Discharge the high voltage capacitor.
2) Disconnect the leadwire from magnetron, choke filter
high voltage transformer, and capacitor.
3) Remove the screw holding the high voltage
transformer to the Insulator-U.

F. AIR GUIDE ASSEMBLY REMOVAL
1) Remove the screw on the Bracket upper and lift out
the Bracket upper.
2) Remove the mounting screw from magnetron,
upper chamber and front plate.
G. MAGNETRON REMOVAL
1) Remove controller assembly, Bracket upper and air-
guide from upper.
2) Disconnect the leadwire from the high voltage &
choke filter transformer and Magnetron.
3) Carefully remove the mounting screws holding the
magnetron and the wave guide.
4) Remove the magnetron until its dome is clear from
the wave guide.
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
JIG
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.
