Talking LENNOX G60DF will not turn over.....

This unit was manufactured in 2009. I just purchased the home. It was installed in 2010 it seems. Simply put, the furnace turns on - I see the blue flame.... I hear sounds like it is working..... Then it "craps out". I think I was getting errors about "flame sensor" error... Then when I leave it on for a bit... I get a specific error about it failed so many times it simply does not want to try again. That is real bad I bet, right? Might eventually fry a board or something.

Is there a good 101 furnace cleaning guide? For this specific error. The "flame sensor". I need to clean some type of rod? I think I was reading about people with similar issues.

Any thoughts? Thank you!

I really don't think you want the furnace to turn over as it would destroy the ductwork and mess up the other piping.

Inside the blower door is a cheat sheet to tell you what the various "blink codes" mean. With what you write I can assume that the flame sensor (flame rod) is not registering the presence of the flame. It will try five times and if still no flame it will go into a "soft lockout" and require either turning the main power off and then on or to turn the thermostat down below room temperature and then back up to reset.

On Lennox furnaces the flame sensor is most commonly on the left-most burner when facing the furnace. It is held in place by a single screw and can be removed fairly easily. Thoroughly clean the rod by rubbing with a Scotchbrite pad. Do not use emery cloth or sandpaper as it will leave deep scratches and cause the rod to need cleaning far too soon. Replace the sensor and make sure that the connecting wire is not damaged and you should be back in business.

If this furnace has not been checked by a qualified serviceperson for several years it would be best to have this done. If at all possible watch the technician so that you can do some it yourself next time.

Very simple. You need to clean your flame sensor. Or perhaps just find it and see if it is connected. It will be located in the burner area. On the opposite side of the igniter. It is white and has a silver rod. Use steel wool to clean.
