Heating systems such as the furnace are one of the most fundamental features of any home, especially since it’s responsible for keeping the space liveable and comfortable throughout the changing seasons. When the colder months come and transform your town into a winter wonderland, you wouldn’t want to deal with a faulty furnace as it can quickly become a major hassle.

Proper maintenance is crucial to ensure it’s running efficiently, though other components such as the heat sensor also deserve your attention. It’s a critical safety feature built into the furnace, which is designed to spot whether the flames are still burning.

Once it dies, the unburned gas can escape the furnace and spread across your space – leading to silent killers like carbon monoxide poisoning or even an explosive hazard. Seeing the pivotal role a furnace heat sensor plays, it’s important to spot the red flags that indicate it’s failing.

Tell-Tale Signs of a Faulty Heat Sensor

A faulty heat sensor can put everyone at extreme risk, but you can easily identify any trouble with the system by noticing the following signs:

  • The furnace turns on, though it quickly shuts off again after seconds;
  • There are cracks and other forms of damages surrounding the covering of the heat sensor;
  • There is soot or corrosion present on the flame sensor;

Cleaning the Flame Sensor

One of the best ways to ensure the heat sensor in your furnace functions properly is to give it some regular TLC. It can also restore it to its full functionality, all of which can happen by doing the following:

  1. Turn off the furnace completely to ensure your safety;
  2. Open up the combustion chamber;
  3. Inside, you’ll find the heat sensor. Remove the sensor and give it a thorough clean up using light-grit sandpaper, emery cloth, steel wool, and other materials that can catch dust, rust, and other dander.
  4. Replace the sensor, close the chamber door, and restart the furnace.

The Bottom Line: The Role of a Furnace Heat Sensor in Protecting Your Home from Carbon Monoxide Poisoning and More

Every working part in a furnace is crucial to ensure it gets the job done properly, and the heat sensor is responsible for ensuring the flame stays alive and burning. Once the fire is out, it can put everyone at home in jeopardy.

In case you notice it failing to perform properly, it’s best to put a professional furnace repair on speed dial. They have the right tools, experience, and technical expertise to identify the root of the problem and ensure everything in your furnace is in good working order.
