GE Artistry stove : analog clock replacement

[Gwynne]

The analog clock on my GE model AGB545DEFWS stove stopped working. I was able to order a new clock to replace it. I am not sure how to safely remove the old clock. Do I have to pull the stove out from the wall to do this, or can I replace the clock from the front without moving the stove out from the wall? This stove is a very basic model with just the clock on the front of it.
