DOOR SENSING SWITCH, PRIMARY INTERLOCK SWITCH, AND MONITOR SWITCH ADJUSTMENT
. 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 control panel assembly, referring to
the procedure of "CONTROL PANEL ASSEMBLY ,
CONTROL UNIT AND KEY UNIT REMOVAL".
If the door sensing switch, primary interlock switch and moni-
tor switch do not operate properly due to a misadjustment,
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 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, secondary 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.
After adjustment, check the following.
. In and out play of door remains less than 0.5mm when
DOOR ASSEMBLY REMOVAL
. 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 hood exhaust louver from the oven cavity
by pushing the right and left tabs of the hood exhaust
louver. (Refer to the procedure of "HOOD EXHAUST
LOUVER REMOVAL".)
5. Insert a putty knife (thickness of about 0.5mm) into the
gap A between the door stopper and the choke cover
as shown in Figure C-3 to free engaging parts.
6. Lift up the door stopper.
7. Now, the door stopper is free from the door assembly.
8. Lift up the door assembly to release the upper and lower
door hinge pins from the upper and lower oven hinges.
9. Now, the door assembly is free.
Note: When the individual parts are replaced, refer to
"Door Disassembly".
DOOR ASSEMBLY RE-INSTALL
. On re-installing door, insert the lower oven hinge to lower
door hinge pin.
2. Insert the upper oven hinge to the upper door hinge
pin.
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 door sensing switch, and primary 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 primary interlock
switch open within .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.)

DOOR REPLACEMENT
3. Shut the door (close the contacts of interlock
switches).
4. Make sure upper and lower oven hinges are inserted
into the upper an lower door hinge pins.
5. Make sure the door is parallel with oven face lines (left
and upper side lines) and door latch heads pass through
latch holes correctly.
6. Re-install the door stopper to the door assembly.
7. Re-install the hood exhaust louver to the oven cavity
front face plate.
Note: After any service to the door;
(A) Make sure that door sensing switch and secondary
interlock switch are operating properly. (Refer to
chapter "Test Procedures".)
(B) An approved microwave survey meter should be
used to assure compliance with proper microwave
radiation emission limitation standards.
After any servicing, make sure of the following :
. Door latch heads smoothly catch latch hook through
latch holes and that latch head goes through center of
latch hole.
2. Deviation of door alignment from horizontal line of cavity
face plate is to be less than .0mm.
3. Door is positioned with its face pressed toward cavity
face plate.
4. Re-install outer case and check for microwave leakage
