You need to replace the thermocoupling.
Thats the flame sensor, and they cost around 8 bucks.

If the gas valve does not recieve signal from the sensor that there is flame it shuts down all gas flow.

I have a six-year old AO Smith Model 50-100 that goes out intermittently and is getting harder to light and stay lit. Had the thermocouple replaced today, and it still won't light and stay lit. I am...


1st thing I would check would be the chimney. Take a match and light it, stick it near
the draft hood of the water heater, be carefull it might be hot. If the match gets blown
out, then you have a backdraft problem. Because it does not happen all the time, perhapsit only does it when you have a strong wind.

Turn off the gass and break the union apart, turn on the gas for a little bit to bleed the
air out of the line. Turn the control on water heater to pilot or lowest setting. Follow
the lighting instructions, if it still does not light then my guess would be the gas valve.

We have a Rinnai R82VF LPG room heater. When you press the gas button and then turn the temperature control knob to IGN, it lights. When you release the temperature control knob, it springs back to OFF and...


Part of the problem may be, that when you turn the control knob to ignition, you're not holding it in long enough for Thermocouple or Thermopile to thoroughly heat up after the pilot lights. You should hold the bottom down for 30 seconds to a minute, to allow it to heat up. Then, when you slowly release it. If the pilot remains lit, turn the knob to the desire position.

If the above doesn't solve the problem, the Thermocouple or Thermopile (aka Pilot Generator) will need to be replaced.

Hope this helped you. Cheers

If this happens each time the blower starts, you have a crack in the heat exchanger and need to replace furnace. If the blower is not starting, it could be a high limit opening up because of the heat being generated. By pass the high limit circuit to see if it stays on and the blower works. This is only a test procedure, do not continue to run system like this. If you have a manual fan switch, turn it on and then start the heater.

Why would the pilot light ignite then turn off?


If it is a true "pilot" light, it needs to be held down long enough to generate the milivolts needed to prove to the gas valve that he is ready to open, other wise the gas valve would open, not igniting, thus causing a "gas leak". Turn the t-stat OFF, turn gas valve to pilot, push down on pilot knob, light pilot and hold for 2 minutes. After 2 mins let go, and if pilot stays lit, turn gas valve to ON, and turn the stat to heat and turn it up to desired temp. If pilot does not stay lit after doing above, try sanding thermo couple( the thing the flame is sitting in) or just spend the $15 bucks and replace therm couple. azeddysac@yahoo.com

Pilot on logs won't stay lit


Hold pilot button longer. if this doesn't work your Thermopile has gone bad and will not generate enough Millivolts to keep gas valve pilot open. A new thermopile will generate 750 millivolts. It cost less than $20 dollars but is difficult to replace. You should call a certified technician. They will charge you about $100.00

ES 160000 Endless Summer Patio heater won't stay lit


Bad thermocouple that senses the heat from the pilot light. This would be evident if you lite the pilot while holding the button down for about 30 seconds. If the pilot goes out as you release the button on the gas valve replace the thermocouple.

I need to know how to light the pilot on my somewhat old water heater. The model is called the challenger 5 the model number 153.331471


On these older gas water heaters there is a gas control with temperature selection and below that is a removable cover. Once you remove the cover you can gain access to the pilot. You must rotate the knob on the top of the control to the pilot position. When in the pilot position, hold the red button down and light the pilot. Continue to hold the button down after the pilot is lit for about one minute. If when you release the red button the pilot goes out, try one more time. If it goes out again after releasing the button your thermocouple is bad and must be replaced. The thermocouple generates a millivolt electrical current that hold the gas valve in the operating condition when the pilot is lit. When the pilot goes out there is no heat to generate this small electrical field.
