So, I wake up this morning and it's mighty chilly...
Upon further inspection the furnace is sending me code 33, I don't know if it is supposed to switch to 13 with the lights or if i'm supposed to just know that 13 is associated with it.
that's as far as I've gotten with it. I know that the flames have not ignited, I'm going to check the blower fan now. any help would be great.
