What is a Thermocouple and How Does it Work With Your Furnaces Pilot Light?

Oct 14, A furnace thermocouple is a device on a standing pilot gas furnace thats responsible for opening and closing the main gas line to your homes heating system. A slim, rod-shaped flame sensor sits in the path of your pilot flame where it collects and then transfers heat down via a flexible connector (wire or tube) to signal, through an electrical charge, that the main gas valve should freedatingloves.com: Brian Hagan.

A gas furnace thermocouple is a solenoid valve that operates off heat instead of electricity. The thermocouple works in conjunction with the pilot light and the main gas valve. The valve is located in the pilot assembly. The thermocouple is made up of two wires that are welded together and covered furnce the gsa.

This housing is placed in the hottest part of the pilot light what are the most expensive diamond cuts the other end attached to the main gas valve.

The thermocouple acts as a sensor. It senses when the pilot light is burning hot enough to light the gas from the main gas valve. If it senses the heat is hot enough, it will turn that heat into an electric signal and sends it over to the gas valve and tells it to open and let the gas out.

As long as the coupler stays hot thermmocouple will keep the gas valve open, allowing the gas to burn as you have dk using your thermostat control. So you are actually controlling this thermostat.

If the pilot light goes out or gets coolthe thermocouple will stop sending the signal and the main gas valve will close, stopping the flow of gas into the furnace and causing the furnace to shut off.

A thermocouple in a gas furnace detects whether the pilot light is on or not. If the pilot light should accidentally go out, the thermocouple will automatically shut off the gas valve. The reason for this precaution is that without the pilot light, unburned gas will begin to flood the combustion chamber. If this happens, a small spark can lead to an explosion. The thermocouple prevents this flow of gas from . The thermocouple is a gas furnace component located near the pilot light burner. It is a safety device that shuts off the gas if the pilot light goes out or the electric igniter fails. If the pilot light won't stay lit, the thermocouple may be faulty and should be adjusted or replaced.

Gas furnaces are among the best ways to have heating for your home, since they effective heating while remaining very energy efficient. A gas furnace usually costs much less to run than an electric model, for example. However, homeowners sometimes worry about the safety of a natural gas furnace.

The reason for this precaution is that without the pilot light, unburned gas will begin to flood the combustion chamber. If this happens, a small spark can lead to an explosion.

The thermocouple prevents this flow of gas from continuing when there is no pilot light. Some furnaces now use a mercury sensor instead of a thermocouple, but it performs the same function. If a thermocouple fails, your furnace can become potentially hazardous.
