Overview

This OEM Igniter Electrode (part number 1179966) initiates the burner flame on the ICP RGS243LEEA0AAAA gas furnace. On a call for heat the control board energizes the electrode to create the spark that lights the gas at the burner. Igniter electrodes are a common failure point — the tip cracks, erodes, or fouls with oxide, and a furnace that can't establish ignition will lock out and leave the home without heat. Symptoms include audible sparking with no flame, a furnace that ignites then drops out, or repeated ignition-failure lockout codes. The genuine OEM electrode delivers the correct gap, position, and gas-ignition timing for safe, dependable starts.
