kitchen aid inner oven door glass cracked

the inner glass on our oven/range door has cracked. the part number fr the glass is ap3008062. it is number 15 piece in the exploded parts view of the door on this site (one of 2 shown). can someone let me know what steps need to be followed to change this item and the required pieces (besides the glass) that may require ordering from this site. thank-you in advance for the info!!
