MONITORED LATCH SWITCH, STOP SWITCH AND MONITOR SWITCH ADJUSTMENT
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 activated 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.
After adjustment, make sure of following:
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 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 stop switch and the
monitored latch switch open within 1.8mm gap
between right side of cavity face plate and door when
door
is
opened.
3. When the door is closed, the contacts (COM-NO) of
the stop switch close.
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.)
