Product review (3 stars): Nasty Oder and HIGH surface temperatures
I too had the problem with this GE range (but the Black model) and like you GE was as useless as they were for you.  I had to run the Self-Clean procedure 4 times at 5 hrs each time in order for the smell to go away even when trying to cook something in the oven at 350 degrees.

Be aware that when doing the Self-Clean, the top of the oven (where the burners are), the metal of the electronic controls (where the knobs are and the keypad), and the front of the oven will get to over 180 degrees.  The sides of the electronic control panel during the Self-Clean cycle will get to over 220 degrees.

Also when cooking something in the oven at 450 degrees the metal of the control panel with the knobs and electronics get to over 125 degrees and the side of the control panel gets to over 155 degrees.

I asked GE if this was expected or normal and they brushed me off and said that is how they designed it.

I do not know if all hidden-element, glass-top ranges are like this but GE would rather not have customers know this.
