I have a GE dual fuel range with convection option. I have not had good success baking with
the convection option. I even adjusted the temp and time as suggested. Other people on this board have had similiar bad expericences with convection baking, so I have stuck with regular old baking. A downside to the convection roast feature is that it can cause drippings and juices to evaporate out of the bottom of the roasting pan, which can be problematic if you need them to make gravy. Pretty much the ONLY time we use the convection feature is to reheat leftover pizzas or to recrisp stuff like that.
If you figure out how to use the convection option and start getting good results, please share... maybe I'm just doing something wrong.
Good Luck.
