Two burners spark, two don't. But those will light if I open gas by turning knob and then turn one of the burners that DO spark to "lite". Since those spark all burners, the one on which I turned on gas will light. That seems to say that the non lighting burner WILL spark, just doesn't when its knob is turned on.

I cannot find out how to open the stove top to look at the wiring harness. Seems to me that the four screws on the front and back need to be removed, and the two on the right. Looks like it should lift off the bottom pan then, but it won't.

Need help on how to get into the thing, and also should I look for TWO faulty controls, a wiring harness that goes under those four, or a spark module. How can I test for it after I get it open.
