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
0.5mm. 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 firmly.
5. Make sure of the monitored latch switch,
stop switch and monitored switch
operation. If those switches have not
activated with the door closed, repeat step
1 - 4.
After adjustment, make sure of following:
1. In and out play of door remains less than
0.5mm when patches position. First check
latch hook position, pushing and pulling
upper position of the door toward the
oven face. The results (play of the door)
should be less then 0.5mm.
2. The contacts (COM-NO) of monitored latch switch
and stop switch interrupt the circuit before the door
can be opened.
3. The contacts (COM-NC) of the monitor switch
close when door is opened.
4. Re-install outer case and check for microwave
leakage around the door with an approved
microwave survey meter. (Refer to Microwave
