The thermocouple is two dissimilar pieces of metal inside a tiny metal bulb. When heated they then generate a tiny electrical charge that gives a signal to the gas regulator to keep the pilot on.

How do you measure the temperature of a furnace?
You could use a thermocouple.
What is the lifespan of a gas furnace thermocouple?
2 years
What is Thermocouple?
In terms of security, the thermocouple is an integral component of the furnace. A little flame that burns continuously is a thermocouple. It is frequently employed in gas furnaces that have standing pilots. In order to maintain a warm tip, the thermocouple's top is placed in the flame. When the pilot flame goes out, the thermocouple automatically shuts off the gas valve in the furnace. Thermocouples are used in everyday good ,electric power generator etc you can avail thermocouple for best price at partshnc website
Piolet on furnace wont stay lite?
Thermocouple is probably bad and needs replacing.
Where is the thermocople located on the furnace?
At pilot light, pilot light flows around thermocouple.
How do you know if the thermo coupling on your gas furnace is bad?
The thermocouple tells the gas valve to supply gas to the burners. If the thermocouple is bad then the furnace will not work or the pilot will not stay lit. A properly working one will have a reading of at least 12 milliamps.
Why does the pilot light in your furnace go out?
Defective thermocouple or possibly a dirty or clogged pilot orifice.
Would a dirty filter have anything to do with a pilot light going out on a furnace?
Not usually. Probably a bad or dirty thermocouple.
Why wont my mobile home furnace Coleman Model7655-856 turn on?
Check the thermocouple, or find a gas tech to do it.
Why pilot device do not consume power?
If your talking about a pilot in a furnace or fireplace, then its because the gasvalve is powered by a thermocouple. The thermocouple is 2 dissimilar metals fused together, when heated it produces a small amount of electricity to hold the valve open.
Would a pilot light on a gas furnace still work with a defective thermocouple?
Pilot light would work but the main burner would not as the thermocouple proves that there is a pilot light to fire. The main gas valve would not open
Would you smell gas if your pilot light on furnace is out?
modern heaters have a thermocouple that would shut off gas supply if the pilot goes out.
