lights, the next two do not.? I have a relatively new ingitor, it is positioned between flames 1 and 2, but closer to the first. After the first ignition cycle, the first flame lights, but burners 2 and 3 dont ignite, so it shuts down and goes into purge again. Every once in a while they light. I cleaned the flame sensor on 3 also, but that wouldnt matter anyways, because they arent lighting in the first place.My house is getting cold.
