ADJUSTMENT
In case the upper and lower latch switches do not operate
properly due to a misadjustment, the following adjustment
should be taken.
1. Loosen the single (1) screw holding the upper latch hook
to the oven cavity front flange and the single (1) screw
holding the lower latch hook to the same flange.
2. With the door closed, adjust the lower latch hook by
moving it back and forward, and then adjust the upper
latch hook by moving it back and forward, or up and
down.
In and out play of the door allowed by the upper and
lower latch hooks should be less than 0.5mm.
The vertical position of the upper latch hook should be
placed where the upper latch switch has activated with
the door closed.
Vertical position of the lower latch hook is not able
to adjust.
3. Secure the screws with washers firmly.
4. Now, make sure the upper latch switch operation. If
the upper latch switch has not activated with the door
closed, loosen the single (1) screw holding the upper
latch hook to the oven cavity front flange and adjust the
upper latch hook position.
After the adjustment, make sure of the following points:
1. The in and out play of the door remains less than
0.5mm
at latched position. First check the upper latch
hook position, pushing and pulling the upper portion of
door toward the oven face. Then check the lower latch
hook position, pushing and pulling the lower portion of
door toward the oven face. Both results (plays of the
door) should be less than 0.5mm.
2. The upper and lower latch switches interrupt the circuit
before the door can be opened.
3. The monitor switch contacts close when the door is
opened.
4. Re-install the outer case and check for microwave
leakage around the door with an approved microwave
survey meter.
