This is a genuine OEM hot surface igniter for the ICP/Tempstar/Heil RGS091HTAB0AAAA gas furnace (OEM 1171306), with a matching igniter wiring kit also available (OEM 1188370). The hot surface igniter is the component that glows red-hot on a call for heat to ignite the gas at the burners. When the control board energizes the igniter, it draws line voltage and heats within seconds; once the flame sensor confirms ignition, the igniter de-energizes. Igniters are fragile and wear out over thousands of heat cycles — the silicon nitride or carbide element develops hairline cracks, hot spots, or breaks entirely, leaving the furnace unable to light. The included wiring kit replaces brittle or heat-damaged igniter leads and connectors so you get a clean, reliable connection.
