Oven won't light GE XL44 Range

[kloss1a]

I have a GE XL44 GAS range. The oven just stopped lighting and therefore heating.

Electronic control panels appears to be working as when Start is pressed the display shows 100 degrees but stays there forever as the oven does not light.

The Broil option does work.

Any suggestions as to possible solutions

Thanks
