5. Release upper and lower hinges and the hinge cover from door

assembly.

6. Now, door assembly is free.

NOTE: When individual parts are replaced, refer to “Door Disassem-

bly”.

2. REINSTALLATION

1. Install the hinge cover to the upper hinge. At this time, the harness

of the door assembly should be passed through under the hinge
cover.

2. Insert the upper and lower hinges into door hinge pins.

3. Insert the upper and lower hinges with door assembly into rectan-

gular holes of oven cavity front plate.

4. Make sure that the door is parallel with oven face lines (left and

upper side line) and door latch heads pass through the latch holes
correctly.

5. Fasten upper and lower hinges firmly to oven cavity with two (2)

screws on each hinge.

NOTE: After any service to the door;

1) Make sure that door sensing switch, secondary interlock

switches (1), (2) and monitor switches (1), (2) are operating
properly. (Refer to chapter “Test Procedures”.).

2) An approved microwave survey meter should be used to

assure compliance with proper microwave radiation emis-
sion limitation standards.

3. DOOR ADJUSTMENT

Door adjustment is performed with the door properly installed and
closed and while the oven hinges are loose.

1. Loosen upper and lower hinges with phillips head screw driver.

2. Adjust the door by moving it vertically so that the top of the door is

parallel to the bottom of the control panel assembly.

3. Tighten the upper and lower oven hinge screws.

3.1. 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

door with an approved microwave survey meter. (Refer to Micro-
wave Measurement Procedure.)

NOTE: The door on a microwave oven is designed to act as an elec-

tronic 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 door is not abnormal and do not of
themselves, indicate a leakage of microwave energy from
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.

3. Push the each four (4) positions of the upper side and lower side of

chock cover by your finger as shown in the Fig.C-6, to free engag-
ing parts.

4. Pull the chock cover rightward as shown in the fig.C-6, to free

engaging parts.

NOTE: As the choke cover and door panel are engage at 14 places,
