It could be that the spark gap is just a bit too wide and the spark doesn't jump every time. Take a long-nose pliers and carefully bend the electrode to close the gap just a little bit. The longer the spark, the more it is exposed to the flame.Have a 3 burner stove , back two spark to light. Front one sparks every 3rd or 4th try. Cleaned the ignitor, it isn't bent, propane is fine. Before I order a part would like to know if I am missing something.
Willie, does your range have one spark unit with wires to all the burners, or a separate sparker for each burner? Are you able to swap the wires between the front burner and one of the back ones?I get no spark at all, than after a few tries it sparks. The gap looks the same as the back burners.
