Shut  the  door  (close  the  contacts  of  latch 
switches). 
Make  sure  upper  and  lower  oven  hinges  are  inserted 
into  the  upper  and  lower  door  hinge  pins. 
Make  sure  the  door  is  parallel  with  oven  face  lines 
(left  and  upper  side  lines)  and  door  latch  heads 
pass  through  latch  holes  correctly. 
Secure  three  (3)  screws  holding  the  lower  oven 
hinge  and  the  base  plate  (Left)  to  the  bottom  side 
of  oven  cavity. 
Secure  two  (2)  screws  holding  the  upper  oven 
hinge  to  the  top  of  the  oven  cavity. 
Note:After  any  service  to  the  door; 
(A)  Make  sure  that  all  switches  are  operat- 
ing  properly. 
(Refer  to  chapter 
“Switches  Adjustment”.) 
(B)  An  approved  microwave  survey  meter 
should  be  used  to  assure  compliance 
with  proper  microwave  radiation  emis- 
sion  limitation  standards.  (Refer  to 
Microwave  Measurement  Procedures.) 
DOOR  ADJUSTMENT 
The  door  can  be  adjusted  by  keeping  screws  of  each 
hinge  loose. 
After  adjustment,  make  sure  of  the  following  : 
1.

Door  -latch  heads  smoothly  catch  latch  hook 
through  latch  holes  and  that  latch  head  goes 
through  center  of  latch  hole. 
Deviation  of  door  alignment  from  horizontal  line  of 
cavity  face  plate  is to  be  less  than  1 .Omm. 
Door  is  positioned  with  its  face  pressed  toward 
cavity  face  plate. 
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 
apperance  of  moisture,  light  or  sensing  of 
gentle  warm  air  movement  around  oven 
door  is  not  abnormal  and  do  not  of  them- 
selves,  indicate  a  leakage  of  microwave 
energy  from  oven  cavity.
