Jenn-Air gas valve not working (Wall oven)

I have a Jenn-Air wall oven, when you turn the thermostat on the igniter glows but doesn’t open the gas valve. I recently replaced the gas valve but it still did the same thing. It looks like a simple circuit that goes from the thermostat, to the igniter,and to the gas valve. There is gas and voltage to the valve. Could I have gotten a bad replacement valve or could it be something else?
