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.
[8] DOOR SENSING SWITCH, SECONDARY INTERLOCK SWITCH AND MONITOR SWITCH
ADJUSTMENT
1. Adjustment
If the door sensing switch, secondary interlock switch and monitor
switch do not operate properly due to a misadjustment, the following
adjustment should be made.
1. Disconnect the power supply cord.
2. Remove the outer case cabinet, referring to “OUTER CASE
REMOVAL”.
3. Open the oven door and block it open.
4. Wait for 60 seconds to discharge the high voltage capacitors of the
inverter unit.
5. Loosen two (2) screws holding the latch base angle to the oven
cavity front plate.
6. With door closed, adjust the latch base angle by moving them back
and forth, and up and down. In and out play of the door allowed by
the latch base angle should be less than 0.5 mm.
The position of the latch base angle should be adjusted so that the
plungers of the door sensing switch, the secondary interlock switch
and the monitor switch are pushed with the door closed.
7. Secure the screws firmly.
8. Check all of the switches operation. If each switch plunger has not
been pushed with the door closed, loosen the screws and adjust
the position of the latch base angle.
