DMOR200SS

After adjustment, check the following. 
.  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 door sensing switch and secondary interlock 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
.  Disconnect the power supply cord.
2.  Open the door and block it open.
3.  To  discharge  the  high  voltage  capacitor,  wait  for  60 

seconds.

4.  Remove  the  two  (2)  screws  holding  the  hood  exhaust 

louver to the oven cavity front face plate.

5.  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".)

6.  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.

7.  Lift up the door stopper.
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.

0. 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.

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 with the two (2) screws.

Note:  After any service to the door;

(A)  Make  sure  that  door  sensing  switch  and  primary 

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.

DOOR REPLACEMENT

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 

around door with an approved microwave survey meter.  
(Refer to Microwave Measurement Procedure.)

Note:  The  door  on  a  microwave  oven  is  designed  to 

act as an electronic seal preventing the leakage 
of  microwave  energy  from  oven  cavity  during 
cook cycle. This function does not require that 
door be air-tight, moisture (condensation)-tight 
or light-tight. Therefore, occasional appearance 
of moisture, light or sensing of gentle warm air 
movement  around  oven  door  is  not  abnormal 
and do not of themselves indicate a leakage of 
microwave energy from oven cavity.
