Switch Adjustment
1. Adjustment
1. Disconnect the power supply cord and remove
the oven from wall and remove outer case. (Refer
to procedure of “Removal of Oven from Wall” and
“Outer case Removal”)
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Remove the right panel assembly, referring to the
procedure of “RIGHT PANEL ASSEMBLY AND
POWER UNIT REMOVAL”. If the door sensing
switch, secondary interlock switch and monitor
switch do not operate properly due to a misadjust-
ment, the following adjustment should be made.
5. Loosen the two (2) screws holding latch hook to
the oven cavity front flange.
6. With door closed, adjust latch hook by moving it
back and forth, and up and down. In and out play
of the door allowed by the upper and lower posi-
tion of the latch hook should be less than 0.5mm.
The vertical position of the latch hook should be
adjusted so that the door sensing switch, second-
ary interlock switch are activated
with the door closed. The horizontal position of
the latch hook should be adjusted so that the
monitor switch is activated with the door closed.
7. Secure the screws with washers firmly.
8. Check all of the switches operation. If any switch
has not activated with the door closed, loosen
screw and adjust the latch hook position.
2. After adjustment, check the following.
1. In and out play of door remains less than 0.5mm
when in the latched position. First check upper
position of latch hook, pushing and pulling upper
portion of door toward the oven face.
Then check lower portion of the latch hook, push-
ing and pulling lower portion of the door toward
the oven face. Both results (play in the door)
should be less than 0.5mm.
2. The door sensing switch, and secondary interlock
switch interrupt the circuit before the door can be
opened.
3. Monitor switch contacts close when door is
opened.
4. The contact of door sensing switch and second-
ary interlock switch open within 1.2mm gap
between right side of cavity face plate and door
when door is open.
5. Re-install outer case and check for microwave
leakage around door with an approved microwave
survey meter. (Refer to Microwave
Measurement Procedure.)
