resetting any cooking function.

 

 

 

 

 

STEAM FROM

• When using the convection feature, it is normal to see steam coming out

of the oven vent. As the number of racks or amount of food being cooked

 

 

increases, the amount of visible steam will increase.

FAN NOISE

• A cooling fan or a convection fan (depending on the function you are

 

 

using) may automatically turn on. This is normal. The cooling fan will

 

 

turn on to cool internal parts. It may run for up to 1-1/2 hours in 30″

 

 

models and up to 2 hours in 27″ models after the oven is turned off.

 

 

The convection fan will cycle on and off until the function is over or

 

 

the door is opened.
