Overview

This OEM igniter electrode (part #1179966) is the ignition component that creates the high-voltage spark needed to light the burners on your ICP/Tempstar/Heil RGS243LDFA0AAAA gas furnace. Mounted at the burner assembly, the electrode delivers the spark that ignites the gas/air mixture on each heating call. When an igniter electrode fails or its tip erodes, the furnace will try to light, fail, and lock out — leaving you with no heat. A cracked ceramic insulator, carbon buildup, or a misaligned gap are the most common causes of ignition failure.
