ADJUSTMENT PROCEDURES
To avoid possible exposure to microwave energy
leakage, adjust the door latches and interlock
switches, using the following procedure.
The Interlock Monitor and Primary Interlock Switch act
as the final safety switch protecting the user from
microwave energy. The terminals between “COM” and
“NC” of the Interlock Monitor must close when the door
is opened. After adjusting the Interlock Monitor Switch,
make sure that it is correctly connected.
Mounting of the primary/monitor/secondary switches to
the latch board.
CHECK THE DOOR LATCH AND SWITCH
CLOSING.
NOTE:
The outer cover of the microwave oven is
removed.
(1) Set the microwave oven on its side so that you can
see the latch board and the switches, as shown in
Figure 26-a.
(2) Close the door tightly and check gaps A and B to
be sure they are no more than 1/64
”
(0.5 mm).
See Figure 26-b for close-up view of gaps A and B
(door latches). If all gaps are less than 1/64
”
(0.5 mm), adjustment of the latch board may not
be necessary. Go to Steps 5 and 6 to check the
sequence of the switches.
NOTE:
To correct sequence of the Primary Interlock
Switch, Secondary Interlock Switch and the
Interlock Monitor Switch is very important.
If any gap is larger than 1/64
”
(0.5 mm), you will
need to adjust the latch board”. Go to step 3
and follow all steps in order.
ADJUST THE LATCH AND SWITCH CLOSING
(3) Loosen the two screws holding the plastic latch
board as shown.
(4) With the oven door closed tightly, move the latch
board upward toward the top of the oven and/or
away from the door latch until the gaps are less
than 1/64
”
(0.5 mm).
Hold the latch board tightly in this position until you
check the sequence of the switches in steps 5
and 6.

INTERLOCK SYSTEM
INTERLOCK MECHANISM
The door lock mechanism is a device which has been specially designed to eliminate completely microwave
activity when the door is opened during cooking and thus to prevent the danger resulting from the microwave
leakage.
