Williams Forsaire wall furnace won't light

The pilot light will stay lit, but the burner no longer comes on. I typically heard a click when the valve opens, but I'm not getting that anymore. I suspect the thermocouple, but wanted to know if there were any other items to check out, and any way to verify that the thermocouple is bad before I schlep off to find one.

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

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

How do you turn the pilot light back on? This is an older model, probably about 10 years old or so.


Move the gas valve knob to the PILOT position and press down on the knob. You will be pressing down on a spring loaded safety magnet. Now light the pilot and keep holding down the knob till the thermocouple gets hot enough to produce electrical current and hold that spring loaded magnet in. This is your safety device. If the heat gets too hot the furnace has a fuse in line with that magnet.
When the pilot stays lit by itself without you having to hold down the button then advance the knob to the ON position. Then go to the wall thermostat and turn on the heater.

I'm having the same exact problem... At first we thought was the vent... but the way the flames goes out... it seems that there is "not enough oxygen" more than "blown out by the wind"... right after both main & pilot goes out, I can't even light any external flame inside the chamber... and it doesn't feel like the outside cold air coming in... it just feel like there is some sort of gas in the chamber that's so strong, it prevents flame... and the only thing I can think of is that it doesn't have enough oxygen, but too much natural gas, and flame can't sustain.

Assuming the pilot is clean and sharp. Before replacing the valve, clean any spade connections, those going up to the spill switch in particular. Clean and tighten all 4 connections. Good luck.

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!
