Overview

The ICP ignitor electrode (OEM part 1179966) is the spark ignition component for the RGS303LRAA0AAAA gas furnace. It delivers the high-voltage spark that lights the burner gas during each heating cycle and, on many configurations, also serves as the flame-sensing electrode. A worn, cracked, or carbon-fouled electrode is one of the most common causes of failed ignition, repeated lockouts, and short cycling. Replacing it with the correct OEM electrode restores reliable, on-demand burner lighting and proper flame proving.
