, posted Sat 15 Dec 22:50  
I have a Lennox gas furnace model G21Q3-60. It has been doing this off and on for about a year and now is doing it about ever other time it runs.
Problem is that when you go down to find out why the furnace isn't running the green light is blinking. I shut off the power switch then back on it'll take sometime to run again then when it shuts down after getting back up to temp, it won't restart again.
Where do you think the trouble is?

The next time you see the led light blinking you should not shut off the power to it what you need to do is count how many blinks there are. That will tell you the code. Then look on the inside cover of the furnace and read the code it will tell you the problem. Check your air filter might be plugged up or maybe the flame sensor or a limit switch

That is a Lennox pulse and the code means dirty spark plug. You will need to remove plug and clean it. You should have a Lennox tech that knows that furnace come out and pressure test the heat exchanger. You might want Santa to buy you a furnace for Christmas.
Be careful sometimes you don't get a second chance
