The Thermocouple is the most likely cause. But before replacing it clean out the pilot orifice. Sounds like it may be partially clogged. You should have a nice wide flame that is hitting the thermocouple dead on. The thermocouple is a safety device that shuts the gas off if the pilot goes out. If it is defective no gas will flow. This is a very common problem with gas heaters.

If pilot stay lit, then thermocouple is working.
If pilot will light, then you have gas. If pilot goes out when pilot button is released, then thermocouple is next suspect.

Thermocouple tip must sit in pilot flame.
The pilot light heat applied to two different metals inside thermocouple causes small current.
The current travels back to gas control valve through copper line.
If the gas valve receive this current, then a magnetic switch stays open and allows gas into the gas control valve.
The magnetic switch is on the end of the red button you push down when lighting pilot. Essentially the red button is an override to the magnetic switch.
If the gas control valve does not receive the current, then the magnetic switch does not stay open when you release the red button.
When replacing thermocouple, note that it is not screwed very tight into the gas control valve. Finger tight + 1/4 turn. If it is overtightened, then the small thermocouple current shorts out against the gas control body.

Why would the pilot light ignite then turn off?


If it is a true "pilot" light, it needs to be held down long enough to generate the milivolts needed to prove to the gas valve that he is ready to open, other wise the gas valve would open, not igniting, thus causing a "gas leak". Turn the t-stat OFF, turn gas valve to pilot, push down on pilot knob, light pilot and hold for 2 minutes. After 2 mins let go, and if pilot stays lit, turn gas valve to ON, and turn the stat to heat and turn it up to desired temp. If pilot does not stay lit after doing above, try sanding thermo couple( the thing the flame is sitting in) or just spend the $15 bucks and replace therm couple. azeddysac@yahoo.com

Pilot light will not lite; plenty of propane. What position does the knob need to be in to lite the pilot. I see pilot, on, and off positions. It is a Williams gas unit direct vent, does not blow hot air...


Hello,
The knob needs to be turned so the arrow is pointing at "Pilot". It is the only position you will be able to depress the knob all the way down. Once you light the pilot, keep holding down the knob for 30-60 seconds. When you release the knob, the pilot should stay lit if it's working properly. If not, here's a few things to check. Is the pilot flame blue? Is the flame actually heating the thermocouple end? The thermocouple has to get hot enough to allow the gas to stay on to the pilot. Also look at the tip of the thermocouple. It should be smooth and rounded. If you're pilot flame is a lazy yellow, after time it will burn off the tip of the thermocouple, causing pilot outages. Replacing the thermocouple is usually the easiest fix it and is probably what you will need to do. But if your pilot flame is that lazy yellow, you will also need to clean it by either a tiny broach needle or using canned air (with straw attached). Be careful and because propane is heavier than air, smell low to the floor before lighting it to make sure there is not a gas leak. To be safe, close the gas shut off valve and air out the room before lighting and always follow the manufacturer's lighting instructions printed on the heater. If doing this seems too difficult or scary, then call your local propane co and they will send out a serviceman to fix it for parts and labor. Good luck! Douglas

Pilot turns on but when I switch to turn it on,


When you light the pilot, are you holding it down for 30-60 seconds. When you release the pilot button, does the pilot flame stay lit? Or does it only go out when you turn the knob to on position. Make sure the pilot flame is heating the end of the thermocouple and that it's a strong blue flame, not a lazy yellow pilot flame. Make sure the tip of the thermocouple is not burn't off, which usually happens with lazy yellow pilot flames. Replace thermocouple is nothing else works.

Pilot flame will not stay on


The thermocouple is bad this keeps the gas valve open from the pilot flame telling the gas valve that the pilot is lit and it is okay to turn on the burners.

Wall furnace shuts off after about 10-20 mins


sounds like its not venting properly...it likely is shutting off on a "Spill switch" or "Vent safety switch"....check the vent/chimney first off.....also the pilot could be dirty..,..a lazy pilot tends to blow out easily....pilot should be blue and sharp,,,big enough to fully envelope the thermocouple

Need to light the pilot light


I am not familiar with this particular brand. What type of heater is it? Normal pilot lighting is done by setting the gas valve to the "Pilot" position and then pushing on the valve to manually open the pilot. After this, light the pilot and continue holding the valve for 30sec to give the thermocouple a chance to heat up. Release the valve and it should stay lit. Turn the gas valve to "On" and you're done. If it doesn't stay lit after releasing the valve, replace the thermocouple. If it doesn't light at all, call a technician out to check gas pressure, orifice, and pilot assembly.

The heater in my central heating is not getting turn on but the fresh air and cooling is getting turn on


Check the pilot light.Older standing pilot systems use thermocouples to verify the pilot is burning before the gas valve opens.If the pilot wont stay lit replace the thermocouple.
Newer systems light the pilot.On a call for heat the igniter lights the pilot. When the heat is verified the gas valve opens . Some systems use an circuit board with flashing led lights to help troubleshooting.
