Firstly, I am very impressed how little heat escapes while using the over!  I was under the impression that the over is lighted.  Well yes, but only if you open the door!  There are 3 of the smaller burners (one is a warmer) in the back and only one in the front.  My husband and I use the small burners the most and I don't like reaching all the way to the back.because I don't want to wear out the one in the front.
