I unplugged the range to stop the sparking. Then I went to AppliancePartsPros and looked at some exploded views of the cooktop, burners, controls, etc. to get oriented. I found that there was a switch on the burner control shaft and a reignition module for each burner. I then browsed the Q&A on various parts, and found one reply that said continuous sparking was due to the reignition module. I looked at the video, which featured R&R of the r. module on a stove that used one module hooked to all five burners. Though mine has a separate module for each burner, the process was close enough to see what I needed to do. Got the part two-day air, and it works fine, now. Very satisfied with the experience.
