If your Williams Furnace turns off before the room reaches the set temperature, here's what you can check: * Examine the thermostat's location. It shouldn't be near warm air from the furnace, a lamp, or above a TV or stereo. * The thermostat itself might be defective. Check its calibration or consider replacing it.
Why Williams 3509621A Furnace not producing sufficient heat?
If your Williams Furnace isn't producing enough heat, here are a couple of things to investigate: * The furnace might be too small for the space you're trying to heat. Review the heat sizing calculations to ensure it's adequate. * The furnace may not be burning at its full rate. Check the gas pressure at the gas valve. It should be 4 inches water column for natural gas or 10 inches water column for L.P.G. Also, check for any blockages in the burner orifices.
Why Williams 3509621A Furnace pilot light keeps going out?
If you are experiencing pilot outages with your Williams Furnace, here are some things to consider: * The pilot flame may be too low or too high. Adjust the pilot flame accordingly.

If it's on an outside wall or there's a hole behind it, cold air could be affecting its reading. Try relocating it. * The thermostat itself could be defective. Check its calibration, verify its temperature reading, or replace it. * The valve might be stuck open. In this case, replace the valve.
