Overview

This OEM ignitor electrode (part 1179966) is the original-equipment ignition component for the ICP/Tempstar/Heil RGS303HDAA0AAAA gas furnace. The electrode delivers the high-voltage spark that lights the burner gas at the start of each heat cycle and, on many designs, also serves as the flame-sensing element confirming a successful light. Over time the electrode tip erodes, the ceramic insulator cracks, and the spark gap drifts out of spec — leaving the furnace unable to ignite or unable to prove flame. Common failure symptoms include the furnace clicking/sparking but not lighting, ignition lockout after several failed tries, short-cycling on flame loss, or a cold home with no heat output. Replacing with the correct OEM electrode restores a strong, correctly gapped spark and reliable ignition every cycle.
