This OEM ICP igniter electrode (part number 1179966) is the ignition component for the ICP / Tempstar / Heil RGS243SEFA0AAAA gas furnace. On each heat call the igniter heats to light the burners; over thousands of cycles the element develops micro-cracks and stress fractures until it fails open and the furnace stops producing heat. Because the igniter is the most common no-heat failure point, installing the exact OEM electrode restores reliable, on-spec ignition without guesswork on the silicon-nitride or carbide element.
