Igniters are not working

I have whirlpool gas stove. One day while I was cooking and I tried to ignite the other burner, igniter of the specific burner( left rear) stopped working with a sound and after a few seconds I heard a noticeable sound beneath that burner and all igniters stopped working, even stopped clicking sounds too.:confused.
I watched one of your pro’s video on you tube and ordered part# w10111806 from your store and replaced it but the problem is not solved. Now I need your help that what is the problem and what should I do?
