Re: Gas Water Heater Question A bad thermocouple will not cause the pilot to go out. There should be a small screw to adjust the pilot flame. If you can find nothing else wrong, try increasing it just a little. |

2 edits | said by tp0d:If the tank is less than 2yrs old, you could have a defective control. There is a production run of controls that have exactly the problem you describe. It is made by robert shaw, with a red pilot button on the top left, and black or red larger control knobs. if this is the case, call the manufacturer -j tp0d's picture looks exactly like my water heater--except that I also have a control on the gas line to activate a power vent.
If you have a power outage--even just 10-20 seconds--it can cause the gas supply to be cut and the pilot to go out.
We have a clock radio that we intentionally leave w/ no 9V battery so that it will flash 12:00 for even the smallest power interruption, that way I'll know I have to go manually re-light the pilot.
Do you have a similar power vented setup? If so, is it possible that don't typically have power failures, but in the last few days you've had two small ones?
Also--I should check to see if my control is one of the ones affected! We've had 1-2 occasions where the pilot was out w/o an apparent power failure  |

said by Waterbug:A bad thermocouple will not cause the pilot to go out. Totally wrong. Obviously, you've never tried to light a pilot on a furnace or water heater with a bad one, have you? |

1 edit | No...There is no electrical run to the WH. It works strictly off the thermo couple and the temp sensor.
