A:AnswerAbsolutly, and because of the way the knobs work the flame won't go out when you are simmering. Further the burners are designed with different maximum/ minimum heat outputs so if used properly it's easier not to over heat simmering dishes.
A:AnswerYes.
I believe somewhere in the guide it does say that the fan will alternate off and on while using the convection feature.This seems to be a samsung function.
I've noticed where an LG model will automatically change the set bake temperature to account for the convection but the Samsung just alternates the fan itself.
