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

I can relight the pilot and heater will work for awhile then pilot goes back out. Thermistor has a safety switch inline linked to the high limit safety switch on top of heater. Any suggestions? Thermistor bad, or safety switch fluxuating?? don't know for sure.....

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.

I have a Charmglow patio heater. I have taken it apart and cleaned all openings where the gas comes out, but the flame still goes out after 7-8 minutes. It lights fine but will not stay lit for more than...


From what you have described, it sounds like the Thermocouple is going bad and needs to be replaced. As far as not being able to relight the pilot right away is concerned ... that's a safety feature. The control has to reset itself, before you can relight it, if the pilot goes out on it's on. As it did in your care. It usually takes about 2 - 3 minutes for the control valve to reset itself.

As far as replacing the Thermocouple is concerned, it's somewhat of a specialty item, because of it being in a tall patio heater. However, armed with the Model # of your Charmglow Patio Heater, you can probably purchase one from the manufacturer, Chamglow.

Hope this helps.

My Williams heater Model # 435FXR, is not staying lit after I light the pilot. I changed the thermocouple (even tho I sensed it might not be that), and it still didn't work. I disconnected it again and...


You may have changed the thermocouple, but did you clean the pilot assembly? Dust & dirt can get pulled in and restrict the gas/air mixture. The "blue flame" needs to impinge on the thermocouple in order for it to stay lit. Or, couId there be a possible "crack" in the heat exchanger ?

My Williams wall heater, installed in 2003, has a problem with the pilot constantly going off. The thermocouple is fine. My handyman suspects the limit switch. Any other ideas?


Hi, how did you test the thermocouple?
My problem is that once the heater is fully on (pilot + full flames going) it totally turns off in 3-10 minutes. Then, I have to go through the sequence of relighting the pilot light, etc.
I thought it was the limit switch rollout, but I tested that under various conditions, including within a minute after the heater completely turned off by itself.

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!

I have a coleman evcon and the gas keeps shutting off


The click noise you hear is the magnet inside the valve dropping out. Which means, the voltage that energizes it is low or interupted. Possible, weak pilot flame, bad thermocouple or bad secondary limit switch. This limit switch is located left of the main control. made of ceramic. It can also be a bad gas valve...

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.
