A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds.

Overview

This OEM ignitor electrode (part #1179966) is the spark/sensing electrode for the ICP/Tempstar/Heil RGS243HDFA0AAAA gas furnace. The electrode delivers the high-voltage spark that ignites the burner gas and, on direct-spark systems, also helps prove the resulting flame to the control board. A cracked ceramic insulator, worn electrode tip, eroded gap, or carbon buildup leads to weak or no spark, delayed ignition, or repeated ignition lockouts. Installing a fresh OEM electrode with the correct gap restores fast, reliable burner ignition.
