Can someone help me solve this problem? After years of flawless service, one day 2 of the 5 burners would ignite, but the igniter would keep clicking even after the burner was lit. When I took the cooktop apart, there was a lot of corrosion between the brass venturi tubes and the gas jet holder. I replaced all 5 venturi tubes, and cleaned the threads on the gas jet holders with a wire brush. Didn't solve it. Checked all the igniter wires - replaced the shrink insulatgion on one connector that was cracked. No change. Replaced all the burner bases and igniters. Now the only time the igniters stop clicking is when all 5 burners are lit. Replaced the igniter module; no change. All 5 burners have good spark at the igniters, but it just won't stop clicking!

Does anyone know how the igniters know when the flame is lit?

Thanks, Gene. What a lifesaver you are. I was getting ready to throw in the towel and replace the unit. It never occurred to me that these things are matched. I'm sure I have them cross-wired. I can't find a wiring diagram that tells me which burner is which, but I guess I can trace the wires.

And thanks for that post on the physics behind the igniters. That's a great write-up.
