Overview

OEM igniter electrode (part 1179966) for the ICP / Heil / Tempstar RGS243HSAA0AAAA gas furnace. The igniter electrode is positioned at the burner to ignite the gas/air mixture at the start of each heat call. As the electrode tip erodes, cracks, or develops carbon buildup, ignition becomes weak or intermittent — leading to delayed light-off, rough or noisy ignition, and lockout faults that leave the home without heat. Installing the factory-spec electrode restores a strong, consistent ignition for reliable furnace starts every cycle.

Test — Restore gas and power and confirm prompt, quiet ignition on a heat call.
