SOURCE: Pilot won't stay lit, replaced thermalcouple but

I would remove pilot light assembly and clean orifice and blow out gas line to pilot. Check to see that thermocouple is centered in pilot flame. It is possiblethat your gas valve is bad but it is also possible that you got a defective thermocouple. I would change the thermocouple again as they are much less expensive then the gas valves. The next time when you are sure you have the thernocouple mounted as close to the center of the pilot flame hold the pilot button down for several mins. If none of this works then you may have to change your gas valve.Thank you.

SOURCE: I can light the pilot and the burner will come on,

Most gas water heater problems can be solved by having service technician perform yearly maintenance. Or by doing maintenance yourself.
This maintenance includes cleaning burner parts and combustion chamber, checking gas pressure and supply, bleeding air out of gas line, checking vent draft, making sure air supply is adequate and not exposed to chemicals, cleaning air intake. Also adjusting flame sensor so it is positioned correctly. If water heater is connected to electric circuit, the outlet must have correct polarity.

You can get gas to appliance indicates the gas control valve and water heater are not locked out. But the gas control valve thermostat can still be bad.

SOURCE: pilot light won't stay lit on new water heater

1) Get more air to the water heater and see if problem continues.
2) Read the following pdf-s for things that might apply to your situation.
http://waterheatertimer.org/images/Negative-pressure.jpg
http://waterheatertimer.org/pdf/Attic-Ventilation-and-Pilot-Outage-in-Gas%20Water-Heaters.pdf
http://waterheatertimer.org/pdf/Pilot-light-will-not-stay-lit.pdf

3) Read pdfs above first, and then Add a comment with missing information below, for possible do-it-yourself help.
Does this water heater have a blower?
Is gas valve electronic? Or does gas valve have a dial?
If gas valve is electronic, have you checked outlet with circuit analyzer?
Did pilot light work correctly for a while? If so how long?
Where is water heater located? Hot attic? Closet? Garage? Is area dirty and dusty? Has air intake been cleaned?
What color is pilot flame? Clear blue or yellow-or-orange?
Have you inspected inside of combustion chamber for dripping water?

SOURCE: pilot light is lit but won't turn on water heater

What band and type water heater do you have? And about how old is the water heater? Add a comment with more information.

Following general information applies to tank-type residential water heater.
If pilot light is working, then thermocouple is good. Otherwise, if thermocouple was bad, or fallen out of place, then there would be no pilot flame.
Carefully read instructions for lighting water heater located on front of tank ... make sure you have the gas control valve set to ON.
At this point, troubleshoot varies widely depending if your water heater is older and air enters front of heater, or if water heater was made after 2007-9 and has sealed combustion chamber and FV system.'
Troubleshoot also varies widely depending if you have power vent and which type of gas control valve.

How to light pilot


Assuming it is not an electric spark, but is really the type with a real pilot light:
Move the gas control on the water heater to PILOT
Push the valve handle on the gas controller down to start the gas flowing to the pilot.
Using a match, light the gas at the pilot while holding the gas controller valve handle down.
Keep the gas valve handle depressed for 30 seconds after lighting.
Release the gas controller vale handle - the pilot should remain lit. If not, repeat lighting one more time
Once the pilot remains lit, turn the gas controller valve to On - this should cause the main flame to come on.

NOTE: DO NOT LIGHT A MATCH IF YOU SMELL A HEAVY CONCENTRATION OF GAS - CALL A SERVICEMAN AND VACATE THE AREA

The pilot won't stay lit on gas hot water tank.


Make sure thermocouple tip is seated inside the burner flame.
Make sure thermocouple is not overtightened. Finger-tight + 1/4 turn.
If the pilot lights, then ECO energy cut off is not tripped, but gas control valve might be bad.
Check color of pilot flame: it should be strong and clear blue.
If pilot flame is weak, or color of flame is yellow-orange: Clean pilot orifice and burner and combustion parts on yearly basis.
Clean air intake screen if applicable.
Increase air supply to water heater. Open a window and see what happens.
Check for adequate draft going up chimney using match under vent hood to see if smoke drafts immediately upwards.
Bleed air out of gas line.
Check gas pressure.

Rheem 22V50F1 pilot won't stay lit. Changed thermo couple & it lit, ran then went out. Let it sit overnight & it lit, ran then went out. What next? p.s. The unit is 5 years old. Thanks


If pilot lights and flame is robust and clear blue, and pilot goes out later, then some suspects can be excluded: air in gas line, low gas pressure, thermocouple is overtightened (finger-tight + 1/4 turn), thermocouple not positioned correctly in the flame, dirty pilot tube.
If flame is yellowish and small: then clean pilot tube and combustion parts.
http://waterheatertimer.org/How-to-install-gas-water-heater.html#clean
Remaining suspects can include: air in gas line, low gas pressure, bad gas control valve, tight house so household vent fans pull air down water heater vent that blows out pilot, hot attic with inadequate ventilation, water dripping down vent.

Reliance 606 natural gas water heater - model #640YORT - water does not stay hot. pilot has to be clicked to heat and then u can use hot water til tank empty and it will not continue to heat water.


If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.

Sounds like it. Before replacing gas control, try removing thermocouple connection at valve and spray electrical cleaner in there and blow out with compressed air after, being careful not to get it in your eyes. If no electrical cleaner, try WD-40 and blow out after. If you twist up a piece of fine steel wool and insert in there as well and try to spin/twist it to clean contact inside may help as well. Blow out goo after and re-install fitting and try again. If that doesn"t work, replace gas control.
P.S. Highly recommend certified experienced tech perform this control valve replacement if necessary.
