I just had a service call for my new range as the top front of the oven door gets extremely hot when the oven is on, as does the top front of the range.  I was informed that this is normal as the oven vents from the top of the door. It heats up my kitchen and is very uncomfortable when baking cookies and too hot to touch. However, it does hold the oven temperature very well and bakes evenly. Also, the timer should be louder as you cannot hear it unless you are standing a few feet away.
