Furnace Ignitor parts

A furnace ignitor is a small electrical component that is responsible for generating a spark that ignites the gas burners in a furnace. Furnace Ignitor parts are usually made of silicon carbide or other heat-resistant material and are subjected to high temperatures during operation.

There are two main types of furnace ignitors: hot surface ignitors and intermittent ignition devices. Hot surface ignitors are the most common type and are typically found in newer furnaces. They are heated to a high temperature by an electrical current and are used to ignite the gas burners when the furnace is turned on. Intermittent ignition devices, on the other hand, are typically found in older furnaces and use a spark to ignite the burners.

Failure of the ignitor switch in a furnace results in the system not functioning properly. Some common signs that a furnace ignitor may be failing include the furnace not turning on, the furnace turning on but not heating properly, and the furnace making strange noises when it is turned on. A furnace ignitor replacement should be done on a timely basis if you suspect it is faulty.
