I use a fine file to clean the flame sensor, I found that grit cloth does not get all of the carbon build up off of the flame sensor.
Note: how it shines. this is good for another year. So simple if you know what you are doing.
I hope you found this page useful and that you return to this website the next time you have a problem with your warm air furnace.
