If you mean that the pilot light does not stay lit, you could have a bad thermocouple or a loose connection at the gas valve. Make sure the flame is against the thermocouple. If you mean that the pilot won't light at all, bleed out the gas line a bit more.

I have a William Furnace model #1403622 and the pilot won't stay lit. I keep reading it may need a new thermocouple but where do I buy it and how much does it cost.


Hello, you can buy a thermocouple at any heating and cooling store, they cost between 7 and 15 dollars depending on the length of it.

I have two Williams 1403622 wall furnaces in my children's room. they seem to leak gas not when the furnace is on, only when it's on idle. Both heaters were converted to LP with the Williams Conversion...


When the units were converted, did the installer also adjust the burner's air intake valve to what's required for propane? Sometimes, that's forgotten. Also, I assume all of the connections were leak tested .... not just where the conversion kits were installed, but throughout the heater? The reason I asked this, is that propane enters the heaters at a higher pressure (water column inch) than Natural Gas. Almost twice as much. In which case, it may have loosened the seals in the regulators.

Those are the things, I'd be looking at.

On my williams wall furnace Model # 1403622 the pilot wont stay light, how do i fix this?


Hi,
The problem is with the thermocouple.... this is the metal thing that the pilot flame hits when it is burning....if the flame is not hitting it then it does not get hot enough...

make sure the flame is hitting it....if not then adjust the hood over the flame to get it on the thermocouple...

If it is hitting it then replace the thermocouple....for that heater though the thermo is probably and OEM part and may have to be bought from the manufacturer...
