Yes, that's right. We've had high winds, fairly heavy rain, & water has gotten in my Coleman furnace. Not a lot, but enough. This has happened twice before. I do have a service agreement with my heat provider, but I still have to fork out $100.00 (each) to cover the circuit board. I prob. should have had someone on the roof to look at it, but again, both my car & furnace went out recently, not to mention a death in the family. Anyway, the furnace guy said after initially looking at it the last time, that he would be back w/the required circuit board, & he would check it out for me, (on the roof the metal/chimney-like vent thingie. So, I guess I'll have to be w/o heat for now. I do have a small space heater. Which I now have (on fan only) blowing air into the furnace area to try & dry it (I'm keeping an eye on it). I've really never had this prob. before, I hope I'm makin' sense here, I'm pretty upset. I know prob. nothing can be done, but thanks for listening, take care. 
update: there's a like straight pipe thing, so maybe it's missing a part.
Also there's a piece of siding hanging off my house
