Armstrong Furnace R42495-001 Pilot-Ignitor Sensor Assembly

The Armstrong Furnace R42495-001 Pilot-Igniter Sensor Assembly is an essential component of the HVAC systems and the pilot gas stream safely. It works through a thermocouple which produces a small voltage and is heated by the pilot flame that holds the gas valve open. This mechanism makes it possible for the gas to be ignited instantly thereby avoiding the buildup of gas. The benefits of this part are safety, assured ignition, and stability in heating systems. It is used in furnaces and water heaters, and therefore widely required in residential and commercial applications.
