THERMAL  CUT-OUT  145°C  (OVEN) 
The  thermal  cut-out  located  on  the  top  of  the  oven 
cavity  is  designed  to  prevent  damage  to  the  oven  if  the 
food  in  the  oven  catch  fire  due  to  over  heating 
produced  by  upper  setting  of  cook  time  or  failure  of 
control  unit.  Under  normal  operation,  the  oven  thermal 
cut-out  remain  closed. 
However,  when  abnormally 
high  temperatures  are  reached  within  the  oven  cavity, 
the  oven  thermal  cut-out  will  open  at  145OC,  causing 
the  oven  to  shut  down.  The  defective  thermal  cut-out 
must  be  replaced  with  new  one. 
TURNTABLE  MOTOR 
The  turntable  motor  drives  coupling  to  rotate  the 
turntable. 
FAN  MOTOR 
The  fan  motor  drives  a blade  which  draws  external  cool 
air.  This  cool  air  is  directed  through  the  air  vanes  sur- 
rounding  the  magnetron  and  cools  the  magnetron. 
This  air  is channeled  through  the  oven  cavity  to  remove 
steam  and  vapors  given  off  from  the  heating  foods.  It 
is  then  exhausted  through  the  exhausting  air  vents  at 
the  oven  cavity.
