2. Remove the control panel assembly referring to "CON-

TROL PANEL ASSEMBLY REMOVAL".

3. Disconnect the leads from all switches.
4. Remove the two (2) screws holding the latch hook to

the oven cavity.

5. Remove the latch hook.
6. Remove the switch(es) from the latch hook by pushing

the retaining tab backwards slightly and turning the
switch(es) on the post.

7. Now the switch(es) is free.

If the monitored latch switch, stop switch and monitor
switch do not operate properly due to a mis-adjustment,
the following adjustment should be made.
1. CARRY OUT 3D CHECKS.
2. Loosen the two (2) screws holding the latch hook to

the oven cavity front flange.

3. With the door closed, adjust the latch hook by moving

it back and forward or up and down. In and out play of
the door allowed by the latch hook should be less than
0.5 mm. The horizontal position of the latch hook
should be placed where the monitor switch has acti-
vated with the door closed. The vertical position of the
latch hook should be placed where the monitored latch
switch and stop switch have activated with the door
closed.

4. Secure the screws with washers firmly.
5. Make sure of the all switches operation. If the latch

head has not pushed the plungers of the monitor
switch with door closed, adjust the latch hook position.
At that time, the latch head should have pushed the
plungers of the monitored latch switch and stop switch.
If the latch head has not pushed the plungers of the
monitored latch switch and stop switch with door
closed, loose two (2) screws holding latch hook to
oven cavity front flange and adjust the latch hook
position.

1. In and out play of door remains less than 0.5 mm when

latched position. First check the latch hook position,
pushing and pulling upper portion of the door toward

the oven face. Then check the lower latch hook posi-
tion, pushing and pulling lower portion of the door
toward the oven face. Both results (play of the door)
should be less than 0.5mm.

2. The stop switch  interrupt the circuit before the door

can be opened.

3. When the door is opened the contacts (COM-NC) of

the monitor switch and monitored latch switch close.
And the contacts (COM-NO) of their switches open.

4. When the door is closed the contacts (COM-NC) of the

monitor switch and monitored latch switch open. And
the contacts (COM-NO) of their switches close.

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

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

cavity face plate is to be less than 1.0mm.

3. Door is positioned with its face pressed toward cavity

face plate.

4. 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 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 mois-
ture, light or sensing of gentle warm air movement
around oven door is not abnormal and do not of
themselves, indicate a leakage of microwave en-
ergy from oven cavity.

1. Disconnect the oven from the power supply.
2. Push the door slightly.
3. Remove the door stopper from the choke cover.
4. Lift the door upwards.
