I also suffer from constant spark problem. I thought it may be a wiring harness problem because it stopped when I removed the white wire that goes from the switch to the spark module. That may prove nothing, not sure. I failed to meter out the switch and I live 2 hours away from my daughters cooktop. Is your recommendation to usually replace the spark module based primarily on history that it is what fails most of the time, and it is rare to have the switch harness fail? Or could it be the harness. Can either of these parts be returned?
ANSWER Hello Brent,
If the sparking stopped when you dis-connected the spark switch assembly WB18T10338, a spill has probably gotten into one of the switches and the assembly will require replacement. Most of the time, no sparking is what gets the module replaced.
