This OEM ignitor electrode assembly (part 1179966) is the ignition source for the ICP RGS243HREA0AAAA. On a call for heat, the control board energizes the igniter, which glows hot to light the gas at the burners. Igniters are fragile and degrade over thousands of heating cycles — the silicon-carbide or electrode element develops hairline cracks and eventually fails open, leaving the furnace unable to light. The most common symptom is a system that cycles through its sequence and locks out on ignition failure: the inducer runs, the gas valve opens, but no flame appears. Replacing the igniter with the correct OEM part restores fast, dependable ignition every cycle.
