Overview

This genuine OEM igniter electrode (part number 1179966) is the hot surface ignition component for the ICP/Tempstar/Heil RGS303LREA0AAAA gas furnace. On each call for heat the control board sends voltage to the igniter, which heats to a glowing temperature in seconds and ignites the gas as the valve opens. Because the igniter element is brittle and cycles through extreme heat thousands of times per season, it is one of the most frequent furnace failure points. A cracked or worn igniter produces no heat surface, so the gas valve closes on a failed-ignition lockout and the furnace blows cold air or fails to light entirely. Installing a fresh OEM igniter restores fast, reliable ignition and prevents nuisance lockouts during the heating season.
