Everything You Need to Know About Furnace Flame Sensors
This time of year shows the Twin Cities some of the consistently coldest temperatures on the planet. Living in such an extremely chilly area of the world, you need a furnace that keeps your household warm day in and day out. It’s imperative to understand what parts make up your furnace and how they keep it in peak working condition.
One of the most important parts of your furnace is the flame sensor, and here’s why!
What Is a Furnace Flame Sensor?
In short, a flame sensor is an essential safety feature of your furnace. The flame sensor's main job is to monitor the flame inside the furnace and verify that it’s there.
The flame sensor's location is near the burner assembly to monitor the flame's state accurately.
The most significant purpose of a flame sensor is to catch any potential carbon monoxide leaks.
Are Carbon Monoxide Leaks Dangerous?
Yes. According to the Centers for Disease Control, 430 people die each year from carbon monoxide poisoning, with over 50,000 subsequent hospital visits.
It’s important to note: You should always have a working carbon monoxide detector in your home to detect a carbon monoxide leak.
What Other Dangers Does a Furnace Flame Sensor Catch?
Flame sensors in your heating system also help prevent a possible home explosion due to a gas leak.
When the flame on your furnace goes out, gas will still push from the burner area. Gas can accumulate in one area of the house, and all it takes is a small spark to cause a dangerous and deadly explosion.
Furnace Flame Sensor Replacement
The average lifespan of a furnace is about 15-30 years, while a flame sensor may need replacement every five years.
When installing or replacing a new furnace, you can count on replacing the flame sensor two or three times in its lifespan.
Furnace Flame Sensor Cleaning
If your flame sensor isn’t working correctly, it may not need replacement just yet. A flame sensor may not be working because it’s dirty. It’s best to inspect and clean your flame sensor once a year to assure functionality and safety.
Before you clean your sensor, you must turn off the gas pipe leading to the furnace. Remove the furnace cover and locate the flame sensor. Disconnect the wiring and loosen the screws around the sensor. Use a cloth to clean the flame sensor gently, then re-attach it to its rightful place.
