Only the front two of the 5 burners on this Magic Chef cooktop light. I suspected that the ignitors on the rear 3 burners were faulty, so I switched one of the front working ignitors with one of the rear ignitor on a burner that didn't light. But the ignitor from the rear burner worked fine with the front burner so the problem doesn't seem to be the ignitors.

I see that there are two other parts, the spark module and the spark ignitor switch. Do you think the problem could be either of these parts or something else. Thanks for your help.
