Overview
This OEM hot surface igniter (ignitor electrode, part number 1179966) is the burner ignition component for the ICP/Heil/Tempstar RGS300LSEA0AAAA gas furnace. On a call for heat, the control board energizes the igniter so it glows to a high temperature and lights the burner gas. Hot surface igniters are fragile and slowly degrade with every cycle until they crack or can no longer reach ignition temperature. Typical failure symptoms include a furnace that tries to ignite but never lights, a glowing igniter with no resulting flame, repeated lockouts after three failed attempts, or no glow at all. Installing a fresh OEM igniter restores dependable, first-try ignition and eliminates cold-weather no-heat callbacks.
