GE gas range (slide in) oven repair

The oven on my GE gas (slide in) range is not heating up. I checked my circuit breaker and it’s fine. The stove top burners and broiler is still working fine. Could it be the ignitor? Is it easy to replace?

I have replace my GE oven ignitor with a new part, but oven still won’t light up. What is the problem with this oven burner?
