Whirlpool Accubake Oven Problem

The bake mode on my oven stopped working. I called an appliance repair company out to have it fixed and they replaced the spark control module. Three months later it started doing the same thing but intermittently. Now it will not light at all. I can hear the gas and clicking but it will not light. The broil and burners work fine. Any suggestions on what it might be? I am plenty capable of making the repair myself and hate over paying people for things I can do. I already did a search for similar problems but didn’t find anything exactly similar.

Thanks in advance for any advice.
