Hello everyone,
I have GE Spectra XL44 Self-Cleaning Gas Range. A few days ago the lower burner (for baking) stopped working (when I choose any temperature, red light on the panel shows that it is working, but inside no signs of heat) and, looks like Self-Cleaning is out, too. But the upper burner (for broiling) works fine as it should be. Also, the light works inside as well. Any idea what might happen?! 
Thanks for all your help in advance.
Sergio
