is this a thermocouple?


The pilot may be too small and thus not impinging on the flame sensor adequately. Try tapping on the pilot line to dislodge any dirt or debris out of the pilot assembly to increase pilot flame. If pilot still too small you may have to remove it to clean it out. You can also remove the pilot supply line at the valve and try blowing threough it to clear blockage. Pilot orifice is very small so you may not feel that you are blowing through it. Just reassemble and try again. Be careful not to cross thread the connection. Should turn in by turning with fingers if not then realign and keep trying. Do not force it.

Correct .. clean with fine brush and blow through again and reassemble If that doesn't work then try cleaning in warm water to loosen debris and retry ....OR may have to replace pilot assembly...the orifice is very fine so do not try to clean out with any type of probe...let us know how you make out..hoping for success

I turned it off at the valve, unhooked what I believe was the pilot line blew on it and hooked it back up. It seems to be working properly now, if I wake up to a cold house tomorrow I'll be back. But thanks for getting me to this point.

Did the pilot appear larger? If so..should be good. Let us know if you wake up to a warm house tomorrow!

No I still have to keep the cover off. For the burners to light consistently.

Not everytime with the door off but most of the time. With the door on it lights some of the time but not enough to keep the house warm it may go a couple hours,without lighting when the door is on

I have not tried to clean the flame sensor. I would suspect its connected to the red tube, would you agree?
