On the Williams 3509612 with the eletronic ignition. The heater pilot light won't stay lit! I have held the pilot light button pushed in for at least 2 minutes sometimes a little longer, but to no avail! What is causing the pilot light not to stay lit after the pilot button is released? The gas is flowing good. No problem getting the initial spark. Just when you release the pilot button the pilot light goes out! Thank you for any response!
I have a Williams top vent gravity wall furnace (model 5009622) and I had the same problem. I had to take the cover off the furnace -- screw on top and two at the bottom (open the access door and there is one screw on each side) to get to the reset button for the vent safety shutoff system. On my furnace it's on the left side toward the top of the unit. I pressed the little red reset button and it's been working ever since. If your furnace is properly installed and doesn't have bird's nest in the chimney, it should work fine. Good luck!

Hold the button for 30 seconds, then release. If it goes out right away, you have a bad thermocouple. If the unit does not sense that the pilot light is lit, all of the gas is shut off, including the pilot light.
Open the bottom of the heater and find the gas valve. Turn the black knob to the PILOT position mash it down and light the pilot. When it stays lit without mashin the knob then move that knob to the ON position. Then turn that green knob up.
I would first check the gas pressure to your furnace. Then make sure that burners are clean and watch flames when burner first ignites. I have seen burners that were dirty cause delayed ignition that would create a suction when they came on and extingush pilot and burners.
The next thing I would do is change gas valve. Thank you
You must keep the knob pressed for approx. 30 to 45 seconds in order to allow the pilot thermistor to send the low voltage signal to the gas regulator. Once you've held the knob in for this period of time, you can release it and the pilot flame should continue to burn. Give this a try and see if this works out for you.
Hi, this heater doesn't have a thermocouple, it uses a pilot generator which is more reliable so I doubt you need to change it out. First thing to check is that you have a clean "sharp" blue pilot, you should be able to hear it quietly roar. If it is yellow and appears "soft", the pilot need to be cleaned. The easiest way is to use a straw or tubing of some sort to blow into the pilot, gently tapping the pilot assembly. That should clean it up and heat the pilot generator properly. Tighten the the screw terminals at the control valve to assure good electrical connections and last but not least turn off the thermostat until you get a standing pilot. Good luck and stay warm.
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!
You will first need to turn the control knob to pilot. Then depress the control knob button and hold it. Then press the push button piezo igniter several times until pilot lights or open pilot inspection cover and manually light pilot with match/lighter. You may need to hold the control knob for at least a minute. Then release the control knob and if the pilot stays lit then turn the control knob to on. If it does not light then repeat the process again.
Find the gas valve and turn it to pilot. (Or light) Use a long reach lighter. Light the lighter and press the knob in. Light the pilot and continue to hold the knob in for about 15 seconds. When you release it, the pilot should stay lit. If it doesn't, you need a new thermocouple. That's the small tube that the flame touches when the pilot's lit. They're inexpensive and usually not too hard to replace.
