GE Profile Spectra Broiler not lighting

I'm not an expert, and I'm reading you're post while looking for a solution for our oven, so this is in no way should be taken as a suggested solution, it isn't!!!....here it is anyway: I think it might be a bad ignitor, I have replaced a couple on our stove and both times we had exactly the same symptoms you're experiencing, I think also we're in line for a third ignitor for this "less then 10 year old Magic Chef".
Good luck
