ICP Hot Surface Igniter for RGS303HEEA0AAAA — Ignitor Electrode | Ships Today

Overview

This genuine OEM igniter electrode (part 1179966) is the component that lights the burners on the ICP / Tempstar / Heil RGS303HEEA0AAAA gas furnace. On each heat call the control board energizes the igniter, which glows red-hot to ignite the gas as the valve opens. Igniters are fragile and degrade with every cycle — they crack, develop hairline fractures, or simply burn out, leaving the furnace with no heat even though the inducer and gas valve are working. Replacing it with the correct OEM electrode restores dependable ignition and prevents repeated lockouts. Always handle the new igniter by its ceramic base, never the element, to avoid contaminating or cracking it.
