Frigidaire oven won't light

I have a Frigidaire oven (Model # FGFL66ASA, Serial # VF23004420) that won't light. Power & gas supply is good. Stove top burners light OK. The ignitor glows bright orange but that's all that happens. Is there a way to test the gas valve or a next step in the troubleshooting? Any input is appreciated! TexasFire
