GE Stove top and oven

Last night when I went to turn on my oven when I hit the start button I heard the click that it usualy makes before the oven turns on, but the oven never turned on . My father looked at it, and thinks that may be it’s the igniter, but he can not be completelly sure. Can anyone advise me if it is the igniter, and if it is what is the part number so I can order it ASAP…Thanksgiving is next week, it will be awfully hard to cook a turkey in a oven that’s not working. Thank you in advance for your help. Maggie
