DO you have gas to the pilot while the pilot electrode is arcing? If you don't know disconnect the pilot tubing at the gas valve while there is an arc.

There is no gas when it call to light

If there is no gas to the pilot when you have an arc then the gas valve is suspect

Hi talked with lennox, they said the green wire off the control should have 2 20 miivot when call to heat it does not meaning the control is bad but has been replaced already, thoughts?
Expert:  Rick replied 1 year ago.

I didn't say the control needed to be replaced I said the gas valve was suspect since you indicated you have a spark. When you have a spark that indicates that the pilot valve in the gas valve should open. You're already past the point of a control trial. Since you have a new control I have to assume you have power to the pilot valve since you have a spark.
