4. Carry out the procedure of item 3 around all the circumferences of

the door cover opening.

5. Turn the door cover over again.

6. Put the door packing over the door cover opening if there are any

portions that the door packing is not put correctly.

7. Make sure that the door packing is not tight or not slack. And make

sure that the door packing is put uniformly around all the circumfer-
ences of the door cover opening.

NOTE: 1) Do not scratch the door cover and the door packing.

2) After the door and the oven are assembled, carry out the

microwave leakage measurement test and make sure that
there is no leakage of steam.

[6] DOOR ADJUSTMENT

When removing and/or loosening the oven hinges such as in door
replacement, the following adjustment criteria are taken.

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

1. Loosen the screws holding the oven hinge right and the oven hinge

left to the bottom plate with screwdriver.

2. Insert a spacer of 0.8mm in thickness between the door sealer sec-

tion (lower portion) and the front plate.

3. Adjust the door by moving it so that the door is parallel with the

oven cavity front plate lines (right and left side lines) and the door
latch heads pass through the latch holes correctly.

4. Tighten the screws holding the right oven hinge to the bottom plate.

Then tighten the screws holding the left oven hinge to the bottom
plate.

5. Adjust the latch (see [8]).

NOTE: In order to prevent deformation of parts, lay a soft mat and

then turn the unit on it.

1. After adjustment, make sure of the following:

1. The door latch heads smoothly catch the latch hooks through latch

holes and the latch heads goes through center of latch holes.

2. The door is positioned with its face pressed toward oven cavity

front plate.

3. Reinstall the outer case cabinet 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 elec-

tronic seal preventing the leakage of microwave energy from
the oven cavity during cook cycle. This function does not
require that the door be airtight, moisture (condensation)-tight
or light-tight. Therefore, occasional appearance of moisture,
light or sensing of gentle warm air movement around the oven
door is not abnormal and do not of themselves indicate a leak-
age 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 exhaust the vapor-laden air from the
oven cavity.

[7] DOOR SENSING SWITCH, SECONDARY INTERLOCK SWITCH AND MONITOR SWITCH
REPLACEMENT

1. REMOVAL

1. Disconnect the power supply cord.

2. Remove the outer case cabinet, referring to “OUTER CASE CABI-

NET REMOVAL”.

3. Open the oven door and block it open.

4. Wait for 60 seconds to discharge the high voltage capacitor of the

inverter unit.

5. Disconnect the wire leads from the switch.

6. Keep extending the two stopper tabs holding the switch to the latch

base angle and revolve the switch on the pole.

7. Remove the switch from the latch base angle.

8. Now, the switch is free.

2. REINSTALLATION

1. Reinstall the switch in its place. The door sensing switch is in the

upper position of the latch base angle. The monitor switch is in the
lower position of the latch base angle. The secondary interlock
switch is in the middle position of the latch base angle.

2. Reconnect the wire leads to the switch.

3. Make sure that the monitor switch is operating properly and check

continuity of the monitor circuit. Refer to chapter “Test Procedure
and Adjustment” procedure.
