Question about Water Heaters

I has a gas Whirlpool Water Heater. The pilot has gone out and will not stay lit. I follow the instructions for lighting the pilot and I can see it ignite, BUT it goes out after i release the RESET button after 1 minute (as the directions say).

You most likely have a bad thermocouple. Without the model number I can not provide you witha source for a replacement. However.... before you change the thermocouple try this. Unmount the thermocouple at the gas valve (no gas will escape). Clean the bottom of the thermocouple mounting area inside the case valve as best you can then clean the end of the thermocouple then reconnect it to the gas galve. Try lighting it and as the pilot burns make sure the flame of the pilot is directly ON the thermocouple sensor end. Reposition the thermocouple if necessary. Test again.

If after trying the cleaning procedure it still does not light you have little chouce but to change the thermocouple as part of the troubleshooting process. If it still does not stay lighted after replacing the thermocouple the bad news is the main gas control valve has failed. The good news is... you will have a new thermocouple to work with a new gas control valve if it is replaced.

There is some good reading on this webpage even though it does not display properly:

    Just doing a follow up. Do you have hot water now? I am assuming that you do since there have been no other responses.

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.

Whirpool water heater unable to lit


Whirlpool water heaters are made by American-AOSmith.
Approximate age of water heater is unknown, and type of gas control valve is unknown.

Clean air intake located bottom of heater, using a feather duster.
Get more fresh air to the water heater and see if that solves problem.
http://waterheatertimer.org/images/State-select-air-intake-400.jpg

If you have piezo igniter, then check if it is putting off spark.

If there is no gas at the pilot, then gas control valve is probably bad.

If pilot will light but not stay lit, then change thermocouple.
Watch videos on utube to lean how to replace thermocouple.

I have an old whirlpool gas water heater and the pilot will not stay lit.


Suspects include bad thermocouple, thermocouple slipped down and not in pilot flame, dirty combustion parts and pilot tube, dirty air intake, backdraft caused by other vent fans pulling air down water heater vent, water dripping down vent because of poor venting, air in gas line, low gas pressure, bad gas control valve, hot attic environment, tight house not allowing enough air:

Hot water heater pilot is off. It's not gas,


You have tank-type gas water heater:
Open following link to watch thermocouple replacement.
Make sure new thermocouple sits into pilot flame. Instructions for relighting water heater are usually printed on side of tank.
http://www.youtube.com/watch?v=v0aBPsNg6vo

Gas water heaters need working thermocouple, adequate incoming fresh combustion air with no trace amounts of chemical, open vent to outside that drafts poison combustion product upward, clean burner tubes and combustion parts, correct gas pressure with no air in line, working gas control valve thermostat, no lockout condition such as tripped ECO caused by runaway heating and dirty combustion parts, and no lockout condition such as exposure to flammable vapors.
Open following links for troubleshoot resources:

Pilot light will not stay lit.


More than likely the thermal couple is defective. The thermal couple is a safety device that shuts the gas off if the pilot goes out. If it is defective the pilot light will not stay lit. The thermal couple is the device that the small copper line goes to. It is mounted beside the pilot flame and the flame much touch the TC for it to work. If the flame is not touching the TC bend it until it is in the flame. If it is touching the TC then replace it.

I have a Rheem 50 gal. natural gas water heater mod#21V50-6A followed all instruction and can't get pilot light to stay lit.


The most common reason a pilot light will not stay lit is a bad thermocouple. How old is the water heater? If the pilot light will light, but then go out when you release the safety button, that is a sure sign the thermocouple is bad. You can buy a replacement thermocouple at your local home improvement store. There is a small chance that the control valve has gone bad, but that is highly unlikely.
