NOTE NOTE NOTE NOTE 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.
NOTE NOTE NOTE NOTE NOTE : Detector to be used at the service center is

(Figure 1) (Figure 1) (Figure 1) (Figure 1) (Figure 1)
(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 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.)
