Overview

This genuine OEM igniter electrode (OEM part 1179966) is the ignition source for the ICP/Tempstar/Heil RGS243LTFA0AAAA gas furnace. When the thermostat calls for heat and the gas valve opens, the igniter electrode generates the spark that lights the burner flame. The ceramic-insulated electrode and its precisely gapped tip are exposed to repeated thermal shock and corrosive combustion byproducts, so over time the tip erodes, the ceramic cracks, or carbon buildup prevents a reliable spark. A failing igniter is one of the most common no-heat causes: the furnace runs its ignition sequence, fails to light, and locks out. Installing a fresh OEM electrode restores fast, consistent first-try ignition and eliminates nuisance lockouts on cold mornings.
