GE gas stove broiler and top burners work, but alas, no oven

Is this a bake ignitor problem? or something else? Please advise, I need a birtday cake!

[SIZE=3]Yes, the igniter is the most likely problem. For more on this visit http://www.appliance-repair-it.com/gas-oven-repair.html[/SIZE]

I replaced the igniter, but still no luck. The broiler works, but as soon as I turn the temp down the igniter stops glowing. Noe it seems like an electical problem? Please advise.

Thanks again

Describe to me in detail what happens when you try to use the oven.

Here goes. when the ovem is turned on, it does not warm up and the igniter does not glow. Nor do I smell gas when I open the oven door. When the controll knob is turned to "broil" the igniter starts glowing after about 5 seconds and the flames at the top of the oven comes on and burns nicely. As soon as the I turn the controll to 550 the igniter dims and the gas is turned off. Is there a pilot or somthing that has to be lit in the lower part of the oven?

Thank you for your help
