3.  Secure the latch hook (with two (2) mounting screws) to 

oven cavity front flange.

4.  Make sure that the monitor switch is operating properly 

and check continuity of the monitor circuit.    Refer to 

chapter "Test Procedure" and "Adjustment procedure".

If the door sensing switch, secondary,primary switch and 

monitor switch do not operate properly due to a misadjust-

ment, the following adjustment should be made.
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.  Discharge high voltage capacitor.

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, secondary and third door 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.

6.  Secure the screws with washers firmly.

7.  Check the all switches operation. If the 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.

DOOR SENSING SWITCH, SECONDARY, THIRD DOOR SWITCH AND MONITOR SWITCH ADJUSTMENT

2.  The door sensing switch, secondary and third door switch 

interrupt the circuit before the door can be opened.

3.  Monitor switch contacts close when door is opened.

4.  Re-install outer case and check for microwave leakage 

around door with an approved microwave survey meter. 

(Refer to Microwave Measurement Procedure.)

DOOR ASSEMBLY REMOVAL

1.  Unplug the oven from power outlet and remove the oven 

from wall and remove outer case. (Refer to procedure of 
"Removal of Oven from Wall" and "Outer case Removal")

2.  Remove one (1) screw holding the hood exhaust louver 

to the oven cavity with outer case cabinet, as shown in 
Figure C-2.

3.  Remove the hood exhaust louver from the oven cavity 

by pushing right and left tabs of the hood exhaust louver, 
as shown in Figure C-2.

4.  Remove the sash left from the oven cavity from face 

plate by lifting it up.

5.  Push the door open button and open the door slightly.

6.  Insert an 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.

7.  Lift up the door stopper.

DOOR REPLACEMENT

8.  Now, the door stopper is free from the door assembly.

9.  Lift up the door assembly to release the upper and lower 

door hinge pins from the upper and lower oven hinges.

10. Now, the door assembly is free.

Note:  When the individual parts are replaced, refer to 

"Door Disassembly".

DOOR ASSEMBLY RE-INSTALL

1.  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.

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.
