back and forth and then adjust the latch hook by moving
it back and forth. In and out play of the door allowed by
the latch hook should be less than 0.5 mm.
3. Secure the screws with washers firmly.
4. Now, make sure of the upper and lower latch switches
operations. If these latch switches are not activated with
the door closed, loose the screws holding the latch hook
to the oven cavity front flange and adjust the latch hook
position.
After the adjustment, make sure of the following:
1. The in and out play of the door remains less than 0.5 mm
at latched position.
2. The upper and lower latch switches interrupt the circuit
before the door can be opened.
3. The monitor switch contacts close when the door is
opened.4. Re-install the outer case and check for microwave leakage
around the door with an approved microwave survey
meter. (Refer to Microwave Measurement Procedure.)

6. Remove latch hook assembly from oven flange.
7. Push downward on the one (1) stopper tabs holding each
of the switches place.8. Switches are free.
At this time latch lever will be free, do not lose it.
Re-install
1. Re-install latch lever and each switch in its place, refer to
Figure C-1.
2. Re-connect the wire leads to each switches and fuse
holder.
Refer to the pictorial diagram.
3. Secure the latch hook (with two (2) mounting screws) to
the oven flange.
4. Make sure that monitor switch is operating properly.
CORD HOLDER REMOVAL
1. Remove the one (1) special screw holding the cord
holder to the rear cabinet, using the special driver
LHSTIX DLR4-100T.
2. Now, the cord holder is free.
NOTE: When securing or loosening the special screw,
LHSTIX DLR4-100T type screw driver should be
used.

DOOR DISASSEMBLY
Remove door assembly, refer to ÒDoor ReplacementÓ.
Replacement of door components are as follows:
1. Place door assembly on a soft cloth with latches facing
up.
Note: As the engaging part of choke cover and door panel
are provided at several places, do not force any
particular part.
2. Insert an putty knife (thickness of about 0.5mm) into the
gap between the choke cover and corner portion of door
panel as shown figure C-2 to free engaging parts.
3. Lift up choke cover.
4. Now choke cover is free from door panel.

2. Remove three (3) screws holding lower oven hinge.
3. Remove lower oven hinge from oven cavity bottom
flange.
4. Remove door assembly from upper oven hinge on the
oven.
5. Door assembly is now free.
Note: When individual parts are replaced, refer to ÒDoor
DisassemblyÓ.
6. On re-installing door, insert the upper oven hinge into the
door hinge pin.
Then while holding door in place.
7. Make sure door is parallel with oven face lines (left and
upper side lines) and the door latch heads pass through
the latch holes correctly.
8. Insert the lower oven hinge into oven cavity bottom
flange and then engage the door hinge pin.
Then secure the lower oven hinge firmly with three (3)
mounting screws.
Note: After any service to the door;
(A) Make sure that the upper and lower latch switches are
operating properly.
(Refer to chapter ÒTest ProceduresÓ.)
(B) An approved microwave survey meter should be used to
assure compliance with proper microwave radiation
emission limitation standards.
DOOR ADJUSTMENT
The door is adjusted by keeping the screws of each hinge
loose. The lower oven hinge can be loosened.
After adjustment, make sure of the following :
1. Door latch heads smoothly catch the latch hook through
the latch holes, and the latch head goes through thecenter of the latch hole.
2. Deviation of the door alignment from horizontal line of
cavity face plate is to be less than 1.0mm.
3. The door is positioned with its face depressed toward the
cavity face plate.
4. Re-install outer case and check for microwave leakage
around the door with an approved microwave survey
meter.  (Refer to Microwave Measurement Procedure.)
Note: The door on a microwave oven is designed to act as
an electronic seal preventing the leakage of
microwave energy from the oven cavity during the
cook cycle. This function does not require that the
door be air-tight, moisture (condensation)-tight or
light-tight. Therefore, the occasional apperance of
moisture, light or the sensing of gentle warm air
movement around the oven door is not abnormal
and do not of themselves, indicate a leakage of
microwave energy from the oven cavity. If such
were the case,  your oven could not be equipped
with a vent, the very purpose of which is to exhaust
the vapor-laden air from the oven cavity.

MICROWAVE MEASUREMENT
After adjustment of door latch switches, monitor switch
and door are completed individually or collectively, the
following leakage test must be performed with a survey
instrument and it must be confirmed that the result meets
the requirements of the performance standard for micro-
wave oven.
REQUIREMENT
The safety switch must prevent microwave radiation emis-
sion in excess of 5mW/cm2 at any point 5cm or more from
external surface of the oven.
PREPARATION FOR TESTING:
Before beginning the actual test for leakage, proceed as
follows;
1. Make sure that the test instrument is operating normally
as specified in its instruction booklet.
Important:
Survey instruments that comply with the requirement for
instrumentations as prescribed by the performancestandard for microwave ovens must be used for testing.
Recommended instruments are:
NARDA 8100
NARDA 8200
HOLADAY HI 1500
SIMPSON 380M
2. Place the oven tray into the oven cavity.
3. Place the load of 275 ± 15ml of water initially at 20 ±
5ûC in the centre of the oven tray. The water container
should be a low form of 600 ml beaker with inside
diameter of approx. 8.5cm and made of an electrically
non-conductive material such as glass or plastic.
The placing of this standard load in the oven is important
not only to protect the oven, but also to insure that any
leakage is measured accurately.
4. Close the door and turn the oven ON with the timer set
for several minutes. If the water begins to boil before the
survey is completed, replace it with 275ml of cool water.
5. Move the probe slowly (not faster that 2.5cm/sec.)
along the gap.
6. The microwave radiation emission should be measured
at any point of 5cm or more from the external surface of
the oven.
