Overview

This OEM ICP igniter electrode (part number 1179966) is the ignition component that lights the burners in your ICP Tempstar/Heil RGS243SSAA0AAAA gas furnace. On a call for heat, the control board energizes this electrode to create the spark needed to ignite gas at the burner assembly. A cracked or worn electrode is among the most common reasons a furnace runs the inducer and gas valve but produces no heat. Typical failure symptoms include no ignition on a call for heat, repeated ignition lockouts, short-cycling after failed light attempts, and visible cracks or carbon buildup on the ceramic insulator.
