What is the Igniter?

The igniter is the small, often cylindrical body on the end of a gas valve that opens to allow gas to flow into the furnace. Dirt, dust, and other objects can build up on the igniter, keeping it from operating properly. Cleaning the igniter can help ensure proper combustion and maximize energy efficiency in your furnace.

How to Clean the Igniter

If you have a furnace that uses a gas ignition system, it’s important to clean the igniter regularly. Cleaning the igniter will prevent problems with the furnace, such as poor performance or a lack of heat.

To clean the igniter, remove it from the furnace and place it on a flat surface. Remove any debris or soot that may be clinging to it. Use a wire brush to clean the igniter’s metal surfaces. Be careful not to scratch the surface. Finally, use a dry cloth to wipe off any residual oil or dust.


If you have a gas furnace, there’s a good chance the igniter is dirty. Igniters are small electric motors that start the burn process in gas furnaces. Over time, dirt and dust can accumulate on the igniter, making it difficult to start the furnace. In some cases, the igniter will even fail completely.
