misadjustment, the following adjustment should be made.
4. Loosen the two (2) screws holding latch hook to the oven

cavity front flange.

5. 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 position 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,
primary switch and secondary switch are  activated with
the door closed. The horizontal position of the latch hook
should be adjusted so that the plunger of the monitor
switch is pressed with the door closed.

activated with the door closed, loosen screw and adjust
the latch hook position.

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, pushing and pulling upper portion of door toward the
oven face. Both results (play in the door) should be less
than 0.5mm.
