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. Remove seven (7) screws holding the hood
intake duct R to the oven cavity top plate, the
oven cavity front flange, fan duct, base plate R,
and magnetron duct. And remove the hood intake
duct R.
4. Remove the control panel assembly, referring to
the procedure of "CONTROL PANEL ASSEMBLY
CONTROL UNIT AND KEY UNIT REMOVAL".
5. Remove the two (2) screws holding the 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 secondary
interlock switch and primary interlock switch are
activated with the door closed. The horizontal
position of the latch hook should be adjusted so
that the monitor switch and stop switch are acti-
vated 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.
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 lower portion of the door toward the
oven face. Both results (play in the door) should
be less than 0.5mm.
2. The secondary interlock switch and primary
interlock switch interrupt the circuit before the
door can be opened.
3. Monitor switch contacts close when door is
opened.
4. Stop switch contacts open when door is opened.
5. Re-install outer case and check for microwave
leakage around door with an approved microwave
survey meter.
