The Importance of a Furnace Flame Sensor

Your furnace has many different components that help it to run safely and efficiently. Sometimes you may not know many of these components exist until something goes wrong and you have to have it repaired. It’s important to understand how your furnace works so that you can spot problems quickly.

The Importance of a Furnace Flame Sensor

The sensors on your furnace are essential not only to keep your furnace working properly but to keep your home and family safe while it’s doing so. One of these important safety mechanisms is the flame sensor. When your furnace ignites, the flame sensor produces an electric current which is measured in microamps. If the level of microamps is off kilter, the furnace will not release any gas to ignite the unit. This prevents an accidental fire or explosion from happening if your gas flow is off.

A Dirty Flame Sensor

Without regular cleaning and maintenance, carbon buildup can cause your flame filter to malfunction, which will either stop your furnace from igniting all together or cause it to shut off frequently. If you suspect your flame filter is causing a problem with your furnace, call L&M Heating and Cooling right away. A professional tech will be able to determine if your sensor needs to be replaced or if there is a larger issue causing it to malfunction.

Regular Cleaning Will Prevent Sensor Malfunctions

Seasonal furnace maintenance and cleaning by HVAC professionals is the only way to prevent unnecessary sensor malfunctions. Not only will your sensors and all furnace components have a longer life and work more efficiently, but your HVAC tech will be able to spot problems before they turn into costly repairs. Get your furnace maintenance done before the cold weather hits, so you’re not stranded without heat when you need it most.
