    I made sure everything was tight and I have no gas leaks. There is good gas pressure reaching the gas control valve. The thermocouple has been nearly red hot and still will not stay on.

Did you make sure the connection between the thermocouple and the control is tight and that the tip of the thermocouple is in the flame?

    In that case you were either sold a defective thermocouple or the gas control is toast, I would try one more thermocouple since they are cheap, and only replace the gas control as a last resort

If pilot stay lit, then thermocouple is working.
If pilot will light, then you have gas. If pilot goes out when pilot button is released, then thermocouple is next suspect.

Thermocouple tip must sit in pilot flame.
The pilot light heat applied to two different metals inside thermocouple causes small current.
The current travels back to gas control valve through copper line.
If the gas valve receive this current, then a magnetic switch stays open and allows gas into the gas control valve.
The magnetic switch is on the end of the red button you push down when lighting pilot. Essentially the red button is an override to the magnetic switch.
If the gas control valve does not receive the current, then the magnetic switch does not stay open when you release the red button.
When replacing thermocouple, note that it is not screwed very tight into the gas control valve. Finger tight + 1/4 turn. If it is overtightened, then the small thermocouple current shorts out against the gas control body.

My 606 reliance gas water heater run for 5min and pilot goes out


If the pilot will light and stay lit, then ECO is not tripped, and thermocouple is probably good.
If ECO is tripped, then pilot will have no gas.
Usually if thermocouple is bad or installed incorrectly, the pilot goes out immediately after releasing the pilot knob during lighting.

First thing is to clean water heater air intake and get more fresh air to the water heater and see if that solves problem. Combustion of hydrocarbon requires oxygen that must be pulled into the water heater from surrounding rooms. If water heater is closed off, or located in hot attic that is not correctly vented, or house is tightly sealed, or air intake is clogged, then there is not enough oxygen to support combustion.

Next thing to check is color and size of pilot flame.
If color of flame is NOT clear blue, or if flame is weak, then that says the pilot orifice and burner tubes and burner should be removed and cleaned, along with cleaning combustion chamber.

Additional suspects include combination of things, including: , bad gas control valve, low gas pressure, air in gas line, water dripping down vent and putting out pilot, reverse air flow or backdraft down the vent that blows out pilot, damaged burner parts because of exposure to trace chemicals such as bleach and wax.

Leaking propane is red flag #1 and fire hazard.
Immediately update your insurance and then turn off gas.
If pilot is not staying lit, then gas leak can be cause of pilot problem since pressure on the line is reduced.
Other causes include bad gas control valve, air in the gas line, bad thermocouple, burner parts need cleaning, or all the above.
After fixing leak, replace thermocouple, clean combustion chamber and burner parts, and bleed gas line to remove air.

Have a atwood m#91043 hot water heater.pilot will not stay light.Have changed temocouple.Still the same problem.


If you've replaced thermocouple with new proper one, and you have a good blue flame under it when pilot held on. Try removing the thermocouple where it connects to gas control and spray WD-40 or similar in the hole where the thermocouple was removed from, and take some steel wool (fine) and twist a piece of it small enough to fit in the hole and get to bottom where contact surface is and spin it to clean the contact surface well. Clean it out after with compressed air if possible, then re-install thermocouple and snug it up good and retry it. If that doesn't do it, your going to have to replace the gas control valve.

Make sure flame is good under thermocouple probe so that it gets proper sensing of flame, and if that's o.k., before you change gas control, remove thermocouple fitting where it attaches to gas control and spray wd-40 in the hole and twirl up some steel wool and push it in the hole and twirl it to try and clean the surface inside there as well. Then spray it out with WD-40 once more to flush out shavings etc, and if you have compressed air, blow it out as well. Now re-attach fitting and snug it, then re-try pilot again. If it works, great if not replace gas control. Let me know the results. You do realize that it should be a certified technician who changes that gas control if necessary, correct?

Try removing the thermocouple where it attaches to gas control, and spray a little WD-40 in the hole, then spin a rolled up small piece of steel wool in the hole as well, then blow it out with compressed air if you can. Then reconnect thermocouple. Make sure thermocouple tip is getting good flame under it, and if that doesn't cure it, then it's time to replace gas control.

Atwood water heater burner won't stay lit


It may very well the thermocoupler that is fault. It is that bulb that sits in the pilot flame. when it goes bad or doesn't sense a pilot flame it shuts all gas off. It needs to be replaced. Inexpensive do it yourself fix. Good Luck _Ned_

Pilot light won't stay alight, when i release the knob after lighting, the flame goes out.


hello!! if you changed the thermocouple & the pilot still goes out !! could be a thermostat ( the electromagnet pilot safety ) goes bad !! make sure pilot is clean & should be sharp BLUE pilot !! not yellow & soft !! also hold down the button light the pilot use a digital volt meter set on dc milivolts a brand new thermocouple should test @ 30 milivolts+ - ! & if you have new style water htr with sealed combustion the thermocouple has a safety part of it ! change the thermocouple & make sure your vents for combustion air around the bottom of the water htr has lint & dust built up !!! kiddbrother i work for a gas company doing service !!
