DRAWER ASSEMBLY AND CHOKE REMOVAL

. Disconnect the power supply cord.
2. Open the drawer and keep it open.
3. To discharge the high voltage capacitor, wait for 60
seconds.
4. Remove the both right and left Cook Top Stays.
5. Remove (2) Drawer Support Covers from Choke Cover
as shown in (Fig. D-1).
6. Insert a putty knife (thickness of about 0.5mm) into the
gap between the choke cover and the door frame.
7. Carefully slide choke cover away from drawer as far as
possible.
8. Remove (6) screws from all (3) drawer Support Angles
as shown in (Fig. D-2).
9. Unhook Drawer Support Angles from drawer, then
remove.
0. Now, the door assembly is free and the Choke Cover
can now be removed.

DRAWER SUPPORT ANGLE REMOVAL

. Remove Drawer Assembly and Choke Cover as stated
in "DRAWER ASSEMBLY AND CHOKE REMOVAL".
2. Remove (2) screws from right or left Latch Angle
Assembly, then remove Angle assembly (Fig. D-4).
3. Separate Slide Rails by moving inside lever of Slide
Rails. The Slide Rail will now separate by pulling straight
forward and out (Fig. D-3).
4. At this point, you can replace either Latch Angle Assy
or Latch Angles.
To reassemble, just reverse the above order.
After reassembly, do the following.
(A) Make sure that drawer sensing switch, secondary
interlock switch and monitor switch are operating
properly. (Refer to chapter "Test Procedures".)
(B) An approved microwave survey meter should be
used to assure compliance with proper microwave
radiation emission limitation standards.
After any servicing, make sure of the following :
. Drawer latch heads smoothly catch latch hook through
latch holes and that latch head goes through center of
latch hole.
2. Deviation of door alignment from horizontal line of cavity
face plate is to be less than .0mm.
3. Drawer is positioned with its face pressed toward cavity
face plate.
4. Reassemble the unit and check for microwave leakage
around drawer with an approved microwave survey meter.
(Refer to Microwave Measurement Procedure.)
Note: The drawer on a microwave oven is designed to
act as an electronic seal preventing the leakage
of microwave energy from oven cavity during
cook cycle. This function does not require that
door be air-tight, moisture (condensation)-tight
or light-tight. Therefore, occasional appearance
of moisture, light or sensing of gentle warm air
movement around oven drawer is not abnormal
and do not of themselves indicate a leakage of
microwave energy from oven cavity.
