Description
The Trane SFIGN-406 Silicon Carbide Hot Surface Ignitor 120V is an electrical ignition component used in furnace systems to initiate gas combustion. It is installed within the burner assembly and heats up when current is applied, reaching ignition temperature to light the fuel-air mixture safely and consistently. This ignitor is used in commercial heating equipment as part of the start-up sequence controlled by the furnace control board. It works as a direct ignition source, spark-based systems and supporting accurate burner operation in forced-air heating systems within HVAC systems equipment.
