Overview

This is the genuine OEM ignitor electrode (part number 1179966) for the ICP / Tempstar / Heil RGS303SSFA0AAAA gas furnace. The ignition electrode delivers the spark or ionization point that lights the burner on a call for heat, and on many designs also helps confirm flame presence to the control board. A cracked ceramic insulator, eroded electrode tip, or incorrect gap leads to failed ignition, repeated lockouts, or short cycling on the safety circuit. Installing a fresh OEM electrode restores reliable, on-demand ignition and proper flame-sensing feedback.
