Overview

This OEM igniter electrode (P/N 1179966) provides the spark that lights the burners on the ICP/Tempstar/Heil RGS243HTEA0AAAA gas furnace. The electrode delivers a high-voltage spark across a precise gap to ignite the gas-air mixture at startup. Over time the electrode tip erodes, cracks, or develops carbon buildup, leading to failed ignition, repeated lockouts, delayed light-off, or a furnace that runs the inducer and gas valve but never lights. Installing the correct OEM electrode with the proper gap restores fast, reliable ignition and ends nuisance lockout codes.
