Royal Chef built in gas wall oven

[lgharris]

So I have this built in Royal chef gas stove and up until recently it worked like a charm
I have done a ton of research on this and I have serial #'s.
I've read these were the cheapest appliances but it is still working.
What I am finding is when I turn it on the red light comes on but I do not hear the gas ignite like I usually do.
I have found someone locally to fix it but I need the part. Anyone suggestions.
BTW this still cooks on point, I will cry if I can not fix.
Thanks

I wonder if it might be a bad thermocouple? Although I would think the pilot light would go out. Hopefully somebody will know.
