The
door
lock
mechanism
is a device
which
has been
specially designed to completely eliminate microwave radia-

the door lock mechanism
is repaired, check
microwave leakage according to the procedure specified
in page 19.

Mechanical Function
When the door is closed, the catch under the door handle
snaps on the latch on the oven, locking the oven door.
If
the door is not closed properly, the oven will not operate.
Fig. 4 shows the closed door condition.
When the door is closed, the lower catch pushed the slider
of the interlock monitor switch to bring it "OFF" condi-
tion,
then
the
catches,
upper
and
lower,
individually
engage with the latch and the tip of the catches pushes the
lever which
presses
the button of the primary/secondary
interlock switch to bring them under "ON" condition.

When the handle
is pulled to open the door, as illustrated
in Fig. 5, the catches disengage from the latch, leaving the
lever in a free state, thus the lever is pushed by the switch
button to turn off the switch and open the circuit.
Then
the lower catch releases the slider to bring the interlock
Monitor switch under "ON" condition.
