Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.

How big is the pilot? is it enveloping the top 1/3 of the thermocouple? only the top 1/3?

Expert:  Rick replied 10 months ago.

Please respond to this question. If you can give me a picture of the lit pilot that might help. Does the pilot go out randomly or when you try to light it?
