just wont stay lit.

I have a 40 gal kenmore propane water heater. I have a problem where the pilot light wont stay on. Reading up every one says it the thermopile and so i changed the whole burner unit. Still the same problem. So i changed the thermostat valve.. Still the same problem. Im at a loss to know what is causing it now. Any ideas?

Is your chimney blocked?

I don't think so but will check again tonight

I checked from the top of the chimney all the way to the very top of the water heater. Just can’t figure it out. I think actually the the burner and pilot light is goin out before the water reaches temperature.
