I have an '02 Bradford water heater that isn't working. I

I have an '02 Bradford White water heater that isn't working. I replaced the thermocouple, cleaned the pilot tube end, and checked all connections. I have a nice clean pilot now that stays on. When I turn on the thermostat after setting the dial to "on", I hear a click and the pilot goes out. The burner does not come on. Whereas before I did all that, the burner would light. But the pilot was weak and yellow and only stayed on for 15-30 minutes. Is the valve bad? What else could it be?JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?Customer: I have no idea. I'm new to this sort of repair.JA: Do you plan on doing the work yourself?Customer: probably. If it's too complicated, I'll ask for help.JA: Anything else we should know to help you best?Customer: I used to be a welder.

I have an older aquastar 125 (pilot gets lit with a match);

i have an older aquastar 125 (pilot gets lit with a match); it worked flawlessly for 13 years, then i started having pilot light problems. got some temporary fix by cleaning the pilot circuit, anothe round of burnouts, then disconnected all the thermocouple connectors and brightened them and re-tightened, etc. could always get it to work, but it would blow out after a few days. gave up and went back to tank unit.now a couple years later, am trying again. checked gas filter in pilot tube, got the burner to worker properly for several days, then i blows out again.any ideas>i don't think my unit has the flue tem sensorthanksjm

My hot water heater pilot light will not stay lit. I've gone

My hot water heater pilot light will not stay lit. I've gone through the steps listed on the label to relight it several times and it will not stay lit when I release the pilot knob even after 90-120 seconds. It went out during the night, I was successful in relighting it once and was able to heat the water and then the pilot went out again. What should I check/do next?
