DOOR DISASSEMBLY
Remove door assembly, refer to “Door Replacement”.
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.

DOOR REPLACEMENT
1. Disconnect oven from power supply and remove outer
case.
Remove turntable tray and roller stay from oven cavity.
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 “Door
Disassembly”.
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 “Test Procedures”.)
(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 the
center 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.
