5001912 williams Pilot light will light and stay lit for awhile. After running through a few cycles, the pilot light will go out. I replaced the t coupler but that didn't fix it. flame is in the t coupler. If the flame is small, it is blue in color. If I turn the gas up the flame turns yellow. I think this is normal maybe??

SOURCE: Unable To Keep Pilot Light Lit!

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!

SOURCE: pilot light will not stay lit

Clean the pliot light tube with a Q-Tip and alcohol. Clean 2 inches deep. This will increase the pilot light flame and it will heat up the thermocoupler so it will stay lit.

SOURCE: Pilot adjustment on Williams wall heater

The insert sounds like the cap covering the adjustment screw. Pin hole is for cap removal. Wondering why flame is so high?! Shouldn't have orange flame. If heater doesn't light with lower flame... thermocouple (thing that the flame heats up) may be bad.

SOURCE: Gas fireplace pilot flame won't stay lit.

Hi , you can try and pull the panel on the bottom of fireplace out and check the adapter in fireplace. Sometimes they go bad. When you open in also check to see if there is an adapter plugged in and a option to use the battery operated function. If this goes bad the pilot will not stay lit.

I have a Kirkland patio heater model # PTH-106SS-3G the pilot will not stay lit. Do I need to replace the whole pilot assembly


Hi, If the pilot light goes out when you turn the gas knob to full power on lighting them the most likely cause will be a worn thermocouple, these usually last between 2 years up to 6 years. Found this site very helpful, patio heater problem solving. They have a few solutions to checking patio heaters.

When you first light the pilot works fine after cooker heats up it may cycle a few times and the pilot goes out and then when you try to relight it will only stay lit while the pilot button is being...


Hi there. Try cleaning the thermopile, it must be free of soot or any other form of dirt, the pilot flame should be of good quality, as well as the gas pressure.

How do i light pilot light?


Remove front cover,or just lower section if you can. they usually just need to be lifted up about an inch or so and pulled out. However some have covers that snap in place. After you remove cover locate gas valve. It should have a control knob on top with markings for on, off, and pilot. Set control to pilot. Follow lines from gas valve to burner compartment, one goes to main burner one ,small copper colored line is the thermocouple, other line is the pilot. Turn thermostat down as far as it will go. Make sure gas supply valve in line to heater is on and then depress pilot control , when you have pilot control depressed have a match or other small flame source close to pilot assembly. If it lights then hold down on pilot control for a couple of mins. Slowly release pilot control and if it stays lit turn gas control to on. Turn thermostat up to call for heat and burner should light. If pilot doesn't stay lit when you release pilot control then try again holding pilot down longer. If it still won't stay lit then thermocouple will need replace. Good luck. Thanks

The pilot light will not stay lit, I was told


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.

I can't get the pilot light on my furnace to stay lit.


take out the pilot assembly. there is a small burner and an orfice. the orfice does get clogged if it has not been operated for awhile. you can clean it out with a small sewing needle. if the pilot wont light or stay lit, replace the thermocouple.

Need to turn on pilot light of Williams 3003622 serial # 400518D


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.

Williams Model 435FXR Serial GO222436 Forced air pilot keeps going out


BY THERMISTOR, ARE YOU MEANING THERMOCOUPLE, I.E. WHAT YOUR PILOT LIGHT IS HEATING? IF SO, COULD BE WEAK AND NOT GENERATING ENOUGH VOLTAGE TO STAY OPEN, SHOULD BE BETWEEN 10-25 MILLIVOLTS DC, WHICH CAN BE TESTED AT THE INTERRUPTER LEADS. YOU CAN ALSO BYPASS THE LIMIT DISC TEMPORARILY TO SEE IF THE UNIT STAYS LIT, REPLACE IT IF THE UNIT RUNS.
