Question Pilot Light

I have a heating and air unit. AC is electric and Heat is gas. I have to turn valve to pilot and hold down button while I light pilot. When I let go of button the pilot light goes out. I have held it for several mins. I replaced the themo couple and it is still doing the same thing. the flame is very strong but not all blue. it is a tall lazy flame I guess you could say. Do you think this is a valve problem or a problem with the gas line leading to the pilot or some other problem?

Thanks for you help.

if the flame is on the thermocouple, heating it up, regardless of color it sounds like a bad valve. are there any wires going to the valve at the base of where the thermocouple attaches? sometimes there is a safety wired in that when open will prevent the thermocouple from signalling the valve.

I believe you are right. I took the cover off of the valve and cleaned it from dust and dirt. When I put it back together the light finally lit for about ten seconds. Then something inside the valve clicked and the light went back out. I got it started again and turned valve to on position and the light went back out again. For safety reasons I am going to replace it anyway as it sounds unreliable. Thank you for your help.

God Bless,
