1ST. LATCH SWITCH, 2ND. LATCH SWITCH AND MONITOR SWITCH ADJUSTMENT
If the 1st. latch switch, 2nd. latch switch and monitor switch
do not operate properly due to a misadjustment, the
following adjustment should be made.
1. Loosen the two (2) screws holding the latch hook to the
flange of the oven front face.
2. With the 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 position of the
latch hook should be less than 0.5mm. The horizontal
position of the latch hook should be adjusted so that the
monitor switch is activated with the door closed. The
vertical position of the latch hook should be adjusted so
that the 1st. latch switch and the 2nd. latch switch are
activated with the door closed.
3. Secure the screws firmly.
4. Check the operation of all switches. If each switch has
not activated with the door closed, loosen screw and
adjust the latch hook position.
After adjustment, make sure of the following.
1. In and out play of the 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, pushing and pulling lower portion of door
toward the oven face. Both results (play in the door)
should be less than 0.5mm.
2. The 1st. latch switch and 2nd. latch switch interrupt the
circuit before the door can be opened.
3. The monitor switch contacts close when the door is
opened.
4. Re-install outer case and check for microwave leakage
around the door with an approved microwave survey
meter. (Refer to Microwave Measurement Procedure.)
