What Is a Gas Furnace Thermocouple?

The thermocouple is a small component located near your furnace’s pilot light. The assembly features a sensor that detects when your pilot is operating correctly. When the pilot goes out, it’s up to the thermocouple to send a signal for your furnace to cease operation. Why is that so important? Because if your thermocouple is malfunctioning, your furnace may continue to run while the pilot is out. If the pilot light is not present to ignite fuel, the furnace will simply pump gas into the system, and by extension, into your home. This can be very dangerous.

A malfunctioning thermocouple can lead to:

  • Carbon monoxide buildup in the home, which is highly toxic
  • Fire or an explosion if the pilot suddenly resumes operation

This makes the thermocouple positively necessary for a properly working furnace, as without it, you are exposed to home and life threatening risks. And at GAC, our team never wants to see you put in a bad spot because of a malfunctioning thermocouple!

What Should I Do if My Thermocouple Fails?

Essentially the answer here is always immediately contact a certified HVAC professional. But before you do, you should make absolutely certain that your furnace is no longer running so that you remove the risk of toxic carbon monoxide buildup.

Your thermostat should be set to off, and even better would be to cut power to your furnace entirely until the issue is resolved. This is a very real risk, and the reason why we say to always contact the experts at the first sign of any issues with your pilot light.
