I have a Rudd Achiever 90 series. It iced up on me over the summer while using AC and got wet but AC still worked after I thawed it out. Turned on the heat the other day and nothing. I trouble shot it and found no spark. Took out the control board and was going to replace it. Noticed two resistors fried. De soldered and replaced resistors. Bingo I get Spark now! Still wont light a flame however. I am getting gas because I smell it after the start up cycle. Not sure what else to do. Any help would be appreciated.

I can get the furnace to run if I light it manually. But once its out thats it it wont restart. Should the spark be a continuous? It just sparks once on each cycle.
