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 AND ADJUSTMENT

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 carrying out any repair to the door, do

not bend or warp the slit choke (tabs on the
door panel assembly) to prevent microwave
leakage.

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.

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 stop switch and lower latch switch interrupt the

circuit before the door can be opened.

3. The upper latch switch contacts open when the door is

opened.

4. The monitor switch contacts close when the door is

opened.

5. Re-install the outer case and check for microwave

leakage around the door with an approved microwave
survey meter. (Refer to Microwave Measurement
Procedure.)
