Went to put a roast in & had to make a decision as to which button to push - bake or roast. Had to do a Google to find out what the difference is. I think I had previously only used the "bake" mode.

From internet:
In my GE, convection bake heats with a circular element that is located in the fan housing. Food does not appear to be exposed to any direct radiant heat. With convection roast, the fan works but the heating elements on the top of the oven also come on. This radiant heat does a good job of browning/carmelization but it is pretty robust so you have to be careful.

I thought maybe with all your quilting you found out it works. LOL

As hubby would say when smoke detector goes off Dinners Ready!

I have to agree!

we learn something new every day. have you noticed everything seems to need a temp of 450 degrees now to bake instead of 350. I can't get used to this.
