This is the genuine OEM hot surface igniter electrode (part 1179966) for the ICP / Heil / Tempstar RGS240HTEA0AAAA gas furnace. On a call for heat, the control board energizes the igniter, which glows white-hot to ignite the gas at the burners during the ignition sequence. Hot surface igniters are brittle silicon-carbide or silicon-nitride elements that degrade with every heating cycle and eventually crack, develop hairline fractures, or simply stop glowing. A failed igniter is the single most common cause of a no-heat furnace: the inducer runs, the gas valve waits, but ignition never occurs and the board locks out. Because the element is fragile, it should never be touched on the glow surface during installation — skin oils shorten its life dramatically.
