    Hello All,

    Need to tap into the collective here.

    I've got a gas water heater and the pilot won't stay lit. It just stopped working today. I can go through the re-lighting process and it lights up like it should. I turn the valve to the "on" position and the burner lights up like it should, but it all goes out within a couple of minutes.

    It looks like there's a small component (thermocoupler?) that seems to be pretty easy to get out. Is that the likely culprit? Anything else it could be? Also, is this a DIY project or should I call the pros out?

    Thanks in advance. :wavey:

    I had a similar issue -

    I just adjusted the thermocouple - slight bending of the bracket - so the thermocouple was closer to the pilot light -


    Solved my problem YMMV

    Thank you for NOT calling it a "HOT" water heater, you don't need to heat hot water.:cool:
    Also, if the thermocouple is bad or out of adjustment it seems like the pilot light wouldn't stay on at all. I know that on my gas wall heater if the thermocouple is out of adjustment the light will go out the second I release the pilot light button. I did have a problem with my old gas wall heater where the gas flow thru the pilot light wasn't set right and it'd blow it's self out when the burner would come on. Seems like it may be the same deal with a water heater too. Or, it could just need a good cleaning. See if you can get a pipe cleaner into it to clean out the soot that collects in and around it. Either way be careful, don't want to read about you blowing yourself up.

    This is the same problem I have had when the fix is a new thermocouple.

    Same problem here, 6PM 12/07.

    I have had this problem before and the fix is a new thermocouple. Took the old one out, went to Lowes, purchased the identical part and installed same. About 2 hours down time. Yes, I'm old and slow.

    You can absolutely avoid a plumber on this easy job.

    Like mentioned above, you most likely have a bad thermocouple. They are inexpensive and easy to replace. You may be able to take some fine sand paper and clean off the one you have if you are in a pinch. Sometimes enough carbon can build up to where it does not get hot enough to send a signal to the gas valve.

    Good luck

    I agree I would change the thermocoupler on the HOT water heater.

    Thermocouple replaced.

    Burner heating up water without going out.

    House not blowed up.

    I'd say that's a good day. Thanks everyone for your input. ---VELO

    Another vote for the thermocouple. I am sure you can replace this cheap part yourself. If you still have doubts just search you-tube to see how it is done.

    Good luck to you!:wavey:

    I had the same problem last weekend. Went to store, paid $10 for a new thermocouple, came home, took cover off water heater, noticed dripping, water drops on pilot, pilot goes out, rinse and repeat.

    $10 thermocouple fix turned into a replacement water heater. Still waiting on the plumber who is backed up all week.

    So get out and replace the water heater yourself. It's not that hard, I had to put on in here a year or so ago. Come on, get out there and do it or we'll have to take your man card away.:tongueout::supergrin:

    All you guys replacing thermocouples make sure the pilot is adjusted to a solid blue blue flame like the picture here (random site. no affiliation) http://www.greatdegrees.com/HVAC_System_Repair_Services.htm

    ...and ensure the flame contacts the top 3/8" off the thermocouple to ensure the thermocouple can generate its full millivoltage from it's hot junction.

    Having an extra $10 part on hand can save you a lot of headache and inconvenience.

    Also a good idea to keep some extra furnace (air) filters, humidifier water pads,and water filters if you use them.

    What happens if you don't heat hot water? It gets cold. According to my buddy the plumber, it is a hot water heater.

    I have had the same problem, we replaced the thermocouple (actually my dad fixed it and I held a light). I think the actual piece to fix the water heater cost about $7. It was in like May, back in 2010 I believe. It has pretty much stayed fixed.

    It still takes spells every now and then of going out, but *knock on wood* it will re-light.

    My plumber, also a drinking buddy, carries a bunch of thermocouples in both if his trucks. If a customer needs one he'll have his helper install it for part plus $35 most cases or he'll leave it on your porch and you can pay for the part later. For non regulars it's a show up fee plus time plus part.
