NOTE : If the Interlock Monitor Circuit operates and at the
same time the fuse blows with the Door opened,
be sure to replace the Control Circuit Board because
Relay 2 on the Control Circuit Board, the Door
Sensing Switch and the electric circuit related
on the Door Sensing Switch, which act as
Secondary Interlock Switch.

The SANYO service center should have the designated
detector to measure the microwave energy leakage
after the repair or adjustment.

(1) Loosen 2 screws securing the Lever Stopper.
(2) Adjust the Lever Stopper position so that it is pushed
forward and pull backward until there is about zero
gap between the Latch Lever and the switch body on
the Primary Interlock Switch and at the same time
there is about zero gap between the Door Latch and
the switch body on the Door Sensing Switch when
the Door Latch is securely locked.
(3) Tighten the Lever Stopper screws securely.
(4) Make sure the Interlock Monitor Switch closes after
the Primary Interlock Switch opens when the Door
is opened very slowly, according to “CHECKOUT
PROCEDURE FOR SWITCHES” on page 6.
(5) Make sure the Interlock Monitor Switch opens before
the Primary Interlock Switch closes when the Door is
closed very slowly, according to “CHECKOUT
PROCEDURE FOR SWITCHES” on page 6.
(6) Make sure the microwave energy leakage should be
no greater than 4mW/cm
2
to allow for measurement
uncertainty when measured with a detector.
(All service adjustments must be made for
minimum microwave energy leakage readings.)
