A dirty flame sensor won't prevent ignition. It only shuts down the burner after ignition if no flame is sensed.

No, I take his saying its not lighting as its not lighting. Most people say it lights then goes right back out when its a dirty flame sensor.

Ok. The pilot will light almost always, the burners will light and sometime the pilot will go out after after a few minutes and the burners fail to light.

sequence of opereation:
1 pilot lites first
2 flame senser senses pilot flame
3 the main burners lite off once senser senses pilot flame
4 no flame detected system may lock out depending on type
so try cleaning the flame sensor first step then we go from there, these valves are common for failing and causing intermittant problems but let try the less costly approch first

If you dont know the difference between a gas valve and a Thermocouple, you have no business being inside a furnace my friend. You need to hire a pro, go to school, read a lot, or all three.

Just trying to save you, or your families life. NG + Oxy = Potential Bomb, just add spark.

So did you clean the sensor. And if so is it working correctly now.

I'm going to clean it when I get home. I have morning filled with futsal games. I'll post an update after I clean it.

The sparker electrode is also the flame sensor.You need to clean the electrode.Small strip of emery cloth works good to remove the carbon buildup so its nice and polished looking.The gas valve isn't a smartvalve.Picture i'm looking at showing a standard honeywell intermittant ignition valve with a honeywell s8610u ignition control below it.
