You need to replace the thermocouple. The part can be gotten from Lowes or any hardware store. They are universal just the length is different. Might be to your advantage to take old one off and measure it to get the same length. I would bet it is at least 18 inches off the top of my head. Let me know how it goes ken

hey Carli suspect you mean the pilot goes out as soon as u turn your gas control valve back to the on position!? If this is so, you will have to probable reset the flue spill switch located right at the exaust outlet. OR, SOMETIMES THEY HAVE ANOTHER LIMIT switch in the same circuit in series. If the pilot goes out when u release the pilot press down knob, then it is your thermo couple is loose or fininshed,or the pilot flame is not aimed properly at the sensor (thermo couple)

I have a Vulcan Gas wall furnace that is not working. We cannot work out how to light the pilot light. According to the documents we have it is a 26.4MJ model or the 40MJ model


The Quazar manual says....
-Thermostat control knob to 0
-Then press and hold down * (Star) button
-The press the "ignition" button one or more times until the pilot lights
CONTINUE to hold the * button for at least 15 seconds and release slowly making sure the pilot stays lighted.
-If the pilot goes out.. repeats steps above and hold the * button for much longer than 15 seconds and THEN release the * button slowly.

Hello, i lite the pillot and and start up fire so its working and some time during the day the pillot goes out?


If you have a standing pilot that wont stay lit and you have to keep relighting it, it can only be a couple of things that will do this.
1. Try tighting the thermocouple at the gas valve. (this is a thin copper line that goes from the gas valve and goes to the pilot light.)
2. Make sure that the tip of the thermocouple is in the pilot light flame.
3. Make sure that the thermocouple is clean.

if you have done these and it still doesnt stay lit, buy a new thermocouple.

Can't light a vulcan heritage gas heater, the pilot light lights, but as soon as I try to lift my finger off the button to ignite the heater, the pilot flame always goes off.


Hi and welcome to FixYa, I am Kelly.

What you are experiencing is the lack of a signal from the thermocouple to the gas valve. I.e. the thermocouple is not passing heat information at all. This is caused by either a defective thermocouple, a dirty mating area where the thermocouple connects to the gas valve or... an improperly positioned thermocouple that is not "in the flame" with the pilot lit.

  • First make sure the FIRE end of the thermocouple is in the flame when lit. (reposition if necessay)
  • Next disconnect the thermocouple by unscrewing the fitting on the top of the gas valve. (No gas will come out) Clean the metal mating area as best you can and then re-install the thermocouple. Just a good snug fit. Once you feel it come snug add 15 degrees of tightening motion with a wrench.
Attempt to light the pilot... wait 45 seconds to 1 minute while holding the pilot button down before letting it up. If it stays lit.... GOOD JOB. If it goes out the next step is to replace the thermocouple. If after replacing the thermocouple it does not stay lit the remedy is to replace the gas valve. There are no short cuts and the sequence of repairs is just as I stated in order.

You can remove your old thermocouple and walk in to almost any appliance parts supply or Plumbing and heating supply to purchase the correct thermocouple without a part number. They will match it up with yours.

Thanks for choosing FixYa,
Kelly

Pilot light willignite but fire wont light soon as you release pilot button gas goes out


There is a small copper probe that runs from the gas valve to the pilot assembly. This is called a Thermocouple or pilot safety. Remove it from both ends and take it to a good hardware store for a replacement. They come in sizes to fit most applications but it is OK to get a longer one, just coil up the extra. No gas will escape while you are removing the Thermocouple.

The pilot light will stay lit. Go to turn on heater and stays on briefly and goes out The heater wont stay lit.


If the fan comes on and blows out the pilot light then you need a new furnace because that's the sign of a crack in the heat exchanger. Need a little better description. Do the burners light then the fan come`s on and then it goes out completely?

The pilot light has a thermocouple that allows gas to the pilot light while the flame is burning. If flame goes out it shuts gas off to the pilot jet. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. It seems that your thermocouple is faulty and needs to be replaced if pilot light keeps going out.

Hi you will need to replace the thermocouple. This is the copper tube that screws in to the gas valve and goes back and mounts along side of the pilot. Most will pull straight out. When they go out, the pilot will light when you hold the red button down, but as soon as you release it off it goes. You can but this thermocouple at any hardware store. They come in different lengths, But I would get a 36" one. They will coil up so they wont be in the way. Its better to have a longer one then one that's to short. Make sure the tip is in the flame, or it will do the same thing. It has to get very hot to keep and produce milivolts to keep it on.Please don't forget to rate me on this as I know you will be kind. This will solve your problem for sure.

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.
