GSR21-80 using 60J0001 Pulse Ingnition Control

It got a little chilly last night and my wife said turn on the furnace.



I set the thermostat to heat and it came on for 10 minutes. It locked itself out.



I had another controller so I hooked it up. It ran for about 10 minutes and the led went out on that one too.



I checked the pressure switch, replaced the air flapper, checked the intake and output piping.



Any thoughts?

    We have not abandoned you

    I am looking to find my Lennox Pulse manuals so I can research the problem. I will get back to you.
