I have read all previous post about the Viking ignitor problem.
I have a 6 burner viking range.
BUt I'm stuck. About 2 weeks ago my right four burners did not spark anymore, after reading I ordered a new ignitor module. I installed it, and turn on the one burner at a time, it lights but spark continues until all four are on. I clean all ignitors, checked connections, etc. Still same problem. I got desperate and swap Line & Neutral, and back again. Well after that, I was able to get the two pairs of diagonal burners to work without sparking.
I'm stuck, should I call now for repair service or check the ignitor switches?

Thanks
