Hi, I’m 90% certain one igniter is dead on my [This post ](http://www.appliancepartspros.com/partsearch/model.aspx?model_id=232182"]Bosch cooktop NGP736[/URL]. All igniters would constantly spark until I unplugged the left rear igniter, and now 3 of 4 work properly (and the constant sparking has stopped). I can see the igniter has a lot of crusty build up.
I’ve purchased AP2821597 but I’m not certain how to install it. It’s too large to install via the top knob hole. I lifted the cooktop and looked at the enclosure but didn’t see anything obvious. It appears I need to disassemble it which seems like a lot of effort to replace the igniter.
The parts diagram indicates the right-hand enclosure panel is removable on its own, but this was not obvious when I lifted it. Did I miss something obvious?
