You likely have a bad thermocouple. Go to a hardware store and pick one up. You will need to shut off your furnace and remove the little copper wire that goes into your gas valve where you are holding down the button to light the pilot. Don't remove the larger silver tube that is for your pilot valve to supply the gas to the pilot.  Follow the copper line and try to pull straight down out of the pilot assembly and it may slide right out. If it doesn't you will need to remove the pilot assembly so go ahead and remove the larger silver tube from the gas valve as well. Take out the one or two screws mounting the pilot assembly usually a 1/4 inch or 5/16 nutdriver should be the proper tool.  Once removed unscrew the thermocouple and put in the new one. Reassemble. Careful not to bend your silver pilot tubing too much otherwise you will need to replace that as well. Always check for gas leaks around your pilot tube after reinstalling parts.

Pilot light ok when release finger pilot goes out


Your thermo couple is bad. Thats the copper tube that goes from the gas valve to the pilot. It senses thats the pilot is lit. Thats not working thats why it goes out. You can get a new one at lowes or home depot for about ten bucks its pretty easy to change just dont kink it when you put it in. It will just plug in at the pilot and screw in at at gas valve.

I have a rheem fury model 21v30s and the pilot will light and heat the water but once the burner plate goes out the pilot goes out as well. How do I fix this issue without replacing the water heater? I...


Open a nearby window to let in plenty of air and see if problem continues.
Problem might be something simple like vent backflow blowing out pilot, or more complicated like bad gas control, or combination of problems listed below.
Suspects include:
Faulty gas control thermostat.
Air in gas line.
Low gas pressure.
Hot attic air.
Insufficient air, or dirty air intake.
Dirty combustion parts, and tubes.
Thermocouple not sitting in flame.
Thermocouple tightened too much. Finger tight + 1/4 turn. No joint compound or teflon tape.
Bad venting.
Backflow of air down vent pipe caused by tight house and/or other vent fans in house.

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

I have a Rheem gas furnace, model # RGAA-100C and need help lighting the pilot. The instructions on the metal plate tell me to set the valve to off, then to pilot, push the valve down until lit, and then...


Hi, follow what I say and it is very easy. The knob that says off, on, and pilot, is where you need to start. You don't want to turn it off now, as its been off for awhile now. Turn the knob slowly pushing down on it until you fill it go down. The knob will go down believe me. When this happens, keep holding it down as this is what starts the gas to the pilot which is back under the burner, under it. Just take a flash light and you can follow the aluminum tubing back and where it stops is where you light it with something long with a match in it or a small rolled up paper. Keep the knob down the whole time you are lighting it. When it lights, keep the knob pushed down for about another minute. Then slowly release the knob and the pilot should stay on. Once you have it on, turn the knob to on, not off. If you turn it the wrong way, it will go off and you will need to start over again. Once it stays on by itself, turn your thermostat up for heat and the burner will light and come on. Just remember that the pilot where you light it is where the tubing goes back under it, as the pilot gas goes through it. You will need a light. Look at the knob with a good light and it will tell you which way to turn it. In the pilot position, the knob will press down to let the pilot gas in, and you can reach back and light it. Then turn knob on. Pilot should stay light. Turn on thermostat and it will fire up. Let me know how it goes. You may have to try a couple of times.

Williams debonair wall heater + pilot light problems


THE flame from the pilot should shoot past the thermo-couple and heat this up and make a small amount of mili- amps to prove the pilot light is lit. ..So if the flame doesn,t go past the thermo-couple it won, make mili-amps or its tme to change out the thermo-couple, They only cost lest than $8:00 and you can change it!
