I have two furnaces in my old (1895) house. The older furnace,in the basement has been a source of aggravation for a while, but is currently operating like it should. The newer furnace, in the attic, is dated 4/23/2005. It is a horizontal Luxaire, unit model gm8s080a12uh11b. It has suddenly developed the nasty habit of not starting. I have followed the instructions on the side, but it will not start (means will not ignite) and when I look in the viewhole on the side, all it shows me is two red leds inside blinking. Any comments? Yes,the gas bill has been paid...
