    It could have dirt clogging it. We blow ours out with a straw when they have trouble staying on. However, it's so dangerous that you might want to get a plumber to check it out. It would be horrible if carbon monoxide is escaping to your room.

  • Another option is to call your gas company. They will come out for free for an inspection. Sometimes same day. Hopefully it is something simple.

    Vexie, I work in HVAC. This problem could be caused by several things. First, change the filter. Poor airflow will cause it to shut down. Second, the flame sensor may be corroded. Remove the sensor (it's next to the flame) and sand gently with 120 grit sandpaper. Other possible causes are that the flame is rolling out and triggering the roll out switch (you need a technician) or the gas valve could be failing (technician).

    Try the two simple steps first.

    If you can light the pilot and it stays lit but goes out when you turn to on. Sounds like the thermocouple is bad and needs to be replaced.

    Don't mess around with it, get a repairman to look at it right away. Carbon monoxide, gas leak, or explosion are possible.

    Agree with others. Get a licensed gasfitter to look at. Messing around with gas appliances is dangerous and could be fatal to you or someone else in the house. Is a life worth saving a few dollars?
