Why Does My Gas Furnace Pilot Light Keep Going Out?

Jan 10, 2014 - The thermocouple is the copper rod you see the pilot flame hitting. It's a safety device that controls a small valve to shut off gas going to the pilot ...

The pilot may no be strong enough to keep the thermocouple active . check to see that the pilot is engulfing the thermocoupler completely.
You may have to adjust the pilot for a stronger flame or you may have to clean the pilot orifice if it is dirty. Hope this helps.

Sounds like the pilot is mounted to far away from the burner. I have seen it happen before where the pilot has detached and the main burner will just keep pumping gas in until it hits the pilot flame and just flash flames and everything goes out.

Or it just could be a bad thermocouple that is going out all the time.

Make sure you have a clean and strong pilot light. Take a rubber tube and blow the pilot head to make sure something didn't partially block your pilot when it was off reducing the heat to the thermocouple or thermopile.

You Need to replace the Thermocouple. You can get them at most hardware stores take the old on with you

The pilot light jet may have got a little bit of dirt or grit in it which is preventing it from keeping alight. If the pilot light has only a weak flame, the whoosh of the main burner igniting can quite often blow out the pilot. Try probing the jet with a fine piece of wire to see it the blockage can be dislodged. You may have to unscrew the jet to clear it by blowing air through it. Make sure gas is turned off first before removing any parts.

The pilot light also has a thermocouple that allows gas to the pilot light while the flame is burning. If pilot flame goes out for any reason, it shuts the gas off to the pilot jet to prevent unburned gas collecting and causing a safety hazard. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. If, after cleaning, the pilot light keeps going out, it would seem that your thermocouple is faulty and needs to be replaced.

If this is a common occurrence, then it may be time to replace the thermocouple that controls the pilot part of the gas valve. If it still keep going out, gas valve may be faulty.

Make sure your pilot flame is hitting the thermocoupler. If not then use air to clean pilot port and try again.

Dirty pilot, you may need a contractor.Tom

The pilot assembly, pilot oriface, and pilot burner should be cleaned and the thermocouple replaced.
