Question about Water Heaters
Some how you have disconnected the sensor that tells the main burner that the fan is on. Its trying to light but cant. On some models there is a air pressure switch that reads the pressure inside the vent pipe itself. It will have a small hose on it and if that has cracked or was not replaced it wont light. This is how its supposed to work--- vent fan comes on,sensor confirms fan is on,hot surface ignighter starts to glow red,and main burner is opened,another sensor confirms that main burner is lit,then hot surface ignighter turns off. Hope this helps.

pilot light will stay on if it is a standing pilot. Turn water heater aqustat down and plug back in. you probably need to clean water heater or replace it. i have drained down a couple of them and took out gas valve and cleaned and put back in worked fine. If you get me a model # i can look it up and tell you some things to try. not sure on yours if it has a different temperature control or if the gas valve is a dual control .

flue is overheating make sure outlet is not obstructed outside and if not that you feel a good air flow coming from it

The slightly warm water makes me think of a thermostat problem. The fact that the heater is 10 years old I wonder how hard your water is. Calcium build up kills water heaters. But the yellow flame you mention could be the results of dirty orfices. May want to have a Pro look at that.

There could be blockage in your water heaters venting on the outside of the home. It sound like the high limit switch has been tripped. Try unplugging the tank and plugging it back in. this will reset the tank. if the problem persists you will want to call your provider for service.
