My pilot light will not stay lit when I let off the button to turn it on and goes out

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!

Sounds like you have a blockage to the main jet and maybe to the pilot light. If you have a compressor just blow the jet and around the pilot light area out from the top and with a bit of luck it will clear it. If not you may need to remove the outer covering and find the pipe to the main jet and again using compressed air just blow it out. Usually not much goes wrong with these apart from blockages every now and then and most of the servicing places just blow them out with compressed air. Just make sure if you remove a pipe you tighten the pipe up properly when re-fitting it. Hope this helps.

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.

Look for dust and lint. Look for them in places where gas should be freely flowing. I had a similar problem with an Empire Corcho wall-mounted propane ceramic catalyst heater. First it was the pilot light, then the #2 ceramic mantle. After horsing around with the gas lines and pressure regulators and trying to re-aim the pilot, it all turned out to be dust and lint in the gas passages. A little dust bunny in the brass pilot tube gave me a pilot light the shape and color of a banana. One puff of compressed air, and I got back my razor-sharp pilot. And some dust in the chimney of the #2 burner kept it burning blue/yellow and blistering paint off the upper surfaces of the heater. A bit of cleaning with a shop-vac put that right. "Passive" heaters are very much prone to this sort of problem because they rely on convection currents (i.e. LOW velocity) to get the job done. Convection currents are notorious dust collectors, as in COBWEB CITY.

If this is a new item then you will need to let the gas run alittle bit longer. If this is a used item then it sounds like you are going to need to replace the flame sensor. You may have to even do it on the new item. But usually for the first start you willl need to hold the pilot down for about 1 minute to really let things heat up in there then when you release all will work
