I hope this answers your question and you click the accept button for me, as this is how I get paid for helping you.
I just checked again and I hear a very slight clicking when I tried each of the 4 burners. BUt there is no spark at the elctode.
Usually I would hear a loud clicking but not anymore.
My wife also has said that it has died a slow death over the last two weeks. Would this make sense based on your answer.
Thank you very much.
