Overview
This OEM hot surface igniter (part number 1171306) is the exact replacement for the ICP Tempstar Heil RGX048KFCA0AAA gas furnace. The hot surface igniter is the component that glows red-hot when the furnace receives a heat call, providing the ignition source that lights the burners. The control board sends line voltage to the igniter element; once it reaches operating temperature, the gas valve opens and the burners light. Because the element is repeatedly heated and cooled, it becomes brittle and eventually cracks or fails open — the single most common cause of no-heat calls in modern furnaces. Typical symptoms include a furnace that runs the inducer and blower but never lights, a glow that is weak or absent, or a visibly cracked igniter element. Handle the new igniter only by its ceramic base, never by the fragile element.
