One of the most important parts of your home heating system is hidden in plain sight. You might not even notice it if you aren’t familiar with it. This small device, known as the furnace flame sensor, is a vital component of every furnace. It adds an extra layer of safety for your home by preventing carbon monoxide from leaking into it. In this post, your cooling and heating installation expert, American Refrigeration Heating and Air Conditioning Co., Inc., shares the importance of a furnace heat sensor.
Important Functions of a Furnace Heat Sensor
Your furnace heat sensor ensures that there’s a flame burning inside of the furnace. If the flame extinguishes, leftover gas can escape from the system and into your home. As discussed earlier, this deadly compound is also known as carbon monoxide, which is deadly and can cause health complications or even an explosion in your home.
Your HVAC contractor will tell you that your furnace heat sensor prevents this from happening by creating a small electrical current to detect the presence or absence of a flame. If the flame dies out, the sensor will turn off the entire system to prevent gas from leaking out, keeping your home and family safe.
Signs of a Failing Heat Sensor
It’s important to ensure that your heat sensor is properly functioning for your family’s safety. Here are some of the signs that may indicate it’s failing:
-
The furnace turns on, but shuts off again after a few seconds.
-
The porcelain cover of the heat sensor has started cracking.
-
There are signs of corrosion and soot on the flame sensor.
Noticing these signs doesn’t immediately warrant a furnace replacement because you can simply clean the sensor to clear the carbon buildup. To determine the true condition of your furnace, be sure to contact a trusted heating contractor to take a closer look at its current state.
