    Maybe i was not clear the pilot has a hole below gas outlet which gas should not be coming from i believe does that mean the pilot has failed and not the thermal couple

If there is no air in the gas line, then at pilot lighting you should smell gas, if not then yes your valve failed. But if it's not igniting, then your lucky and all you have to do is replace the ignitor. you should be able to stick a match in there unless it's enclosed. Be carefull!

    Yes, and excuse me for that, for your info when the pilot flame heats the tip of therm it produces a direct current, (millivolt), the current then travels through wire and energizes the gas valve. If your smelling gas other than the tip of pilot, you may have to replace the pilot, and or gas valve.

Gas fireplace wont stay lit- it is a sealed unit so can taccess the pilot or gas holes in the logs. is it safe to remove glass panel?


Yes, removing the glass is safe, if you do it carefully, so as not to break it. Put it well out of your way, after removing it. In fact, removing it is the only way to access and service the Pilot Assembly and the Burners.

If the pilot won't stay lit, there are several things that can cause this on a Direct Vent Gas Fireplace:
  • The direct vent on the outside of the house is block or clogged.
  • Wind is blowing back through the direct vent, blowing out the pilot.
  • Low gas pressure
  • A dirty pilot.
  • The thermocouple and/or Thermopile (part of the pilot assembly) has failed.
If you can provide me with the make and model number of your gas fireplace, I may be able to furnish you with an Owners Manual, that will help you to continue to troubleshoot the problem.

Hope this helped you.

Im calling for heat from the thermastat and control panel, the boiler light and and the fan is running, but no matter how many times i keep re trying the pilot and burner will not commence, is there...


I would check to make sure control on gas valve is in on position and pilot is lit if you have a standing pilot. If you have a spark or hot surface ignitor make sure they are trying to lit pilot. If you have standing pilot model and pilot lit is not on. Turn control on gas valve to off,wait five mins. then turn to pilot. Depress botton and try to light pilot. If it lights hold down for a couple of mins. then release.. If pilot stays lit turn control to on. If thermostat is calling for heat this should bring main burner on. If pilot does not stay lit then replace thermocouple. Hope this helps. Thanks

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

Can not get the pilot light to stay lit


Your pilot has a safety that if it fails will not allow the pilot to stay running once your release the pilot knob. It is called a thermocouple and screws into the gas valve and goes to the pilot assembly. It is usually a copper wire and can be easily replaced. You can find a replacement at better hardware stores or farm centers. It is fine if you have to get a longer one than the factory, however a shorter one may not work.

Pilot is on turn thermostat up but pilot just stays on no flare up in fire box and fan kicks on is it the thermalcupling


If the thermocouple were bad, then chances are the pilot would not remain lit.

Be sure your gas valve is receiving the proper voltage. The gas valve itself may have failed and is not opening. Of if there is no signal to the valve, the thermostat or another electrical component may have failed.


Standing pilot systems are fairly simple, there isn't much that could do wrong.

Can't find instructions on lennox gf 8 series furnace


Does it have a standing pilot light? On new units, there is an igniter and not a pilot. But if you have a standing pilot, you will move the gas valve to "pilot" and push down the red button while holding a flame under the pilot located by one of the jets. Once it lights continue to hold the button down for a minute or so and then release the button. The pilot should stay lit. Then turn the dial to the on position. That's it.......... If the pilot won't stay lit then the thermocouple is bad and needs to be replaced.

GAS WATER HEATER PILOT LIGHT WONT STAY LIT


It could only be the following problems: Therm couple failed, gas valve failed. Therm couple is the cheaper fix it, so it would be your best first try.

Waterheater pilot light willnot stay lit on model number BFG1F5040T3NOV


there is a class action lawsuit against whirlpoof for their "flame lock" water heaters. (in several states). All their support web pages are blank and their phone support operators are in India (and seem to be named Biff or Muffy or some such rubbish..they think it makes them more acceptible than Ajay or Ravi) Either way..the solution is simple...just do what I am doing..(mine is 8 months old)
1. shut off the gas
2. disconnect the water fittings
3. drain the tank
4. Use a hand truck to remove the tank
5. put it on the trash
6. buy something else..ANYTHING else..than a whirlpool water heater.
