Either the pilot light orfice is dirty, and you will need to pull it out and clean it, or the thermocouple is bad. If the pilot goes out as soon as you let the button go then it is most likely the thermocouple. If the pilot stays lit for a few days or hours then you will need to clean the pilot orfice, heres how:
1 turn off the gas supply
2 unhook the main burner gas line from the thermostat, this is the line that goes to the burner
3 unhook the pilot supply line it is usually next to the main burner line
4 unhook the thermocouple from the thermostat
5 remove the burner assembly
6 take the orfice out of the pilot line and clean it out by blowing thru it, use an air compressor if needed.
7 reassemble and light pilot

if water heater will heat a tank of water before the pilot light goes out you need to replce the gas thermostat

sounds like you have the heater set on its highest setting and its tripping the thermal protector. If that trips the water inside has to cool way down before it resets itself. Try setting the temp lower.
One more thing this time of year the water comming into the home is a lot colder this time of year and that makes the heater work harder and takes longer to heat the water. 40 degree water takes longer to heat than 65 degree water in the summer. This also means that it dont take much water cool the water in the water heater faster to luke warn.
If this is new home with a new water hater you might think about going tankless,then you have endless hot water and save money at the same time.

Question posted under Reliance gas water heater.
Add comment for different brand.
Age of heater is unknown.
Status light indicates one of the Honeywell electronic gas control valve.
Status light not blinking indicates that water heater gas control not receiving electrical power for power vent models.
Or thermocouple is bad on non-power vent models

Depending on model, and age, the thermocouple can be tested and replaced. Or entire burner assembly is replaced.

If the gas control valve has gone bad because of power surge or other anomaly, then the power-vent type gas control is removed from tank and replaced, while the non-power-vent model is module and can be snapped off front of unit.

Copy following link for step by step illustration removing burner assembly (and replacing thermocouple or cleaning combustion parts).
Reliance is made by Rheem and probably has tamper proof screws.

Hi Bill,
Your problem now is that the thermocouple is getting weak. I assume that you have checked and cleaned the burner again with no improvement in the function of the burner.....
You may be getting some moisture in the gas which can cause the flame to go yellow, but will notmake it go out...
If everything else is okay, then I would be changing that thermocouple before doing anything else... they are inexpesive and easy to change.

I have had a similar issue with my Reliance heater. The safest thing to do is replace the entire gas control. You will need the model no. and the serial no. to find the correct one. May have one in stock at some place like Ace Hardware, I found mine on the internet after getting the part no. from the Reliance web site parts dept. May be $75 and up. if you are on propane, there will be a setting in the new control to set for propane The orifices in the burner etc. are already set there. Be careful, it is gas. To change the control is easy, you will need a large pipe wrench to wrap around the whole thing and unscrew it. Drain the heater first, open a hot water faucet to aid in this. And be sure to flush the water heater before you re- light. Lots of videos on the internet on the proper steps. And of course turn off the water supply and the gas supply before you start.

I don't see that manual at Reliance and am unsure if this is gas or electric heater.

The crackling noise is from build-up of sediment.
I forget exact reaction that causes the noise.
Water heaters exposed to hard water will create sediment inside the tank.

Look at the flame and see if it's burning blue or yellow. And then see if it's burning all the time. If the flame is yellow and water heater does not make hot water, the thermostat may keep the flame going all the time and use up your gas.

Poor flame color means you should clean the burner or replace the burner. If water heater is exposed to trace amounts of some chemicals, like bleach or pool chemicals or wax, these chemicals get pulled into the burner and will shorten life of burner assembly and combustion chamber.

If the flame is blue and the water is not hot, then the thermostat is the best suspect. The thermostat is part of the gas valve. The gas valve has a copper tube that extends into the water and reads water temperature. If thermostat reads incorrect temp, then the gas valve needs to be replaced with gas valve from local plumbing supply of Lowes.

If the flame is blue, and it runs all the time, then your tank may have a layer of sediment between the flame and the water, and the sediment has caused water heater to become very inefficient.

Now to answer your question:
You can turn up the thermostat dial located on front of tank.
Check your flame and how often burner comes on to determine where problem is.
You can buy a gas valve from Lowes for $65 or from plumbing supply and then replace >> you need a couple wrenches and pipe joint compound and about half a day.
You can clean the burner with wire brush and shop vac.
Remove chemicals from same room as water heater.
If the water heater has sediment build-up, then a new water heater is probably best choice.

You can do some things yourself. If the do-it-yourself steps don't work, then get a new water heater, and you know more about maintaining a water heater because you worked on the old one. Save the new water heater manual. Read the manual because it has ordinary information that will save you money long-term.
