Water Heater pilot light keeps going out?!?

Question

We have just recently started having trouble with our pilot light. It goes out everyday!!! Yesterday we went to light it again and it wouldn't light at all. So we tried to leave it alone for a while and try again and still it wouldn't light. Then I got some dust remover and sprayed it in there to remove dirt and dust and it caused the thing to catch on fire for a sec. SOOOO I was wondering if anyone has any ideas? We have someone coming out to look at it today and I think they are replacing the thermacoupe?

Answer 1

could be the thermocoupler, or bad gas valve, or just a lot of wind in the chimminey!!!  is there alot of soot buildup in th flame chamber??? maybe the coupler just needs adjustment or has a loose connection, they are very sencetive!!!! is just the tip in the pilot ???

Answer 2

Most likely the thermocoupler
