11.Remove the lower door stopper from the door assembly

in a similar way which the upper door stopper is removed.

door hinge pin.

2. Insert the upper oven hinge to the upper door hinge pin.

3. Shut the door (close the contacts of interlock switches).

4. Make sure upper and lower oven hinges are inserted into

the upper an lower door hinge pins.

5. Make sure the door is parallel with oven face lines (left

and upper side lines) and door latch heads pass through

latch holes correctly.

6. Reinstall the upper and lower door stoppers to the door

assembly.

7. Reinstall the 9-pin wire harness into the bottom sash.

The 9-pin wire harness should be held by three (3) tabs

on the bottom sash. And the marking portion on the 9-

pin wire harness should be held by left tab as shown in

Figure C-3.

Note: After any service to the door;

(A) Make sure that door sensing switch and primary

interlock switch are operating properly. (Refer to

DOOR REPLACEMENT

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 :

1. Door 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 1.0mm.

3. Door is positioned with its face pressed toward cavity

face plate.

4. Reinstall outer case and check for microwave leakage

around 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 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.
