Furnace come on and shut right back off
I have 2007 3400RL I just tired to turn on the furnace for the first time this year, the fan come on and then it will lite,but will only stay on a couple of seconds, then off it will do this 3 times and then shut down. I took the cover off on the out side and saw the lite on the circuit board it flash 3 time,the book said the 3 flashes was Ignition Lockout Fault. Has any one else had the same problem.
