SYMPTOM Does  not  reach  convection  temperature  -  as  measured  inside  the  oven  cavity  with  a
suitable temperature detecting device.
CAUSE
Oven operating normally.
REASON
The  heating  concept  of  the  ovens  listed  above  involves  the  elimination  of  the
convection heater as seen in previous ovens.  Hot air is circulated inside the oven by a
fan, and the upper and lower grill heaters provide the heat.
Because  of  this,  the  'Autocook'  menus  and  user  manual  menus  are  specifically
matched to this mode of operation, to take into account the effect of the "direct heat"
from the grills. Although the working temperature may not match the temperature set
by the end user, this direct heat from the grills in operation together with the 'Autocook'
software  produces  the  same  level  of  "doneness"  as  if  the  convection  heater  was
present and in use. The convection fan forces this direct heat into the food to crisp and
brown to the same level as a conventional convection appliance.
Cooking  development  has  shown  that  the  final  results  from  the  'Autocook'  /  user
manual  menus  are  every  bit  as  acceptable  as  with  a  convection  appliance  with  the
heater.
The  differences  in  temperature  recorded  between  an  appliance  with  and  without  the
convection  heater  should  therefore  be  irrelevant  and  more  importance  should  be
placed  on  the  cooking  results  themselves.  As  long  as  all  relevant  instructions,  and
menus, are used on these appliances, cooking results should be as good as any other
convection oven.
