I've had this oven for about 6 weeks.  It replaced the same model I had for 17 years so I was expecting not to have any problems.  Howeve, that is not the case.  I have baked a few batches of cookies and each time the cookies in the back of the oven are more brown than those in the front. I suppose I could turn the cookie sheets halfway through but I should not have to.  I worry about baking a cake.  It will be difficult to turn the pan around without making the cake fall and I don't want a cake that is done on one side and dry and overbaked on the other.  Any ideas?
