ity.

10.Remove the latch hook.

11.Remove the switch(es) from the latch hook by pushing the retaining

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

12.Now, the switch(es) is free.

If the monitored interlock switch, door sensing 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 0.5mm. 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 interlock switch and door
sensing 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 interlock switch and door
sensing switch. If the latch head has not pushed the plungers of the
monitored interlock switch and door sensing 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 0.5mm 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 position, 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 contacts (COM-NO) of the door sensing switch and the moni-

tored interlock switch open before door is opened.

3. When the door is closed, the contacts (COM-NO) of the door sens-

ing switch close.

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

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

5. Reinstall outer case and check for microwave leakage around the

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

1. Door latch heads smoothly catch latch hook through latch holes

and that latch head goes through centre of latch hole. 

Deviation of door alignment from horizontal line of cavity face plate
is to be less than 1.0mm.

2. Door is positioned with its face pressed toward cavity face plate.

3. Check for microwave leakage around door with an approved micro-

wave survey meter. (Refer to Microwave Measurement Proce-
dure.)Deviation of door alignment from horizontal line of cavity face
plate is to be less than 1.0mm.

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.

1. Turn the door cover to the back side.

2. First, cover the four corners of the door cover opening with four cor-

ners of the door packing.

3. Cover all surroundings of the door cover opening with the ditch of

the door packing surely because the section of the door cover
opening is T letter form. Refer to the expansion photograph of the
door packing and the door cover.

4. Turn the door cover to the face side.

5. Cover surely if there is a part where the door packing doesn't cover

the door cover.

6. It is confirmed for the door packing not to stretch over all surround-

ings, not to remain, and to cling uniformly.

• Do not damage the surface of the door packing.

• Confirm there is neither microwave leakage from the door nor
