Overview
This is the genuine OEM igniter electrode (part number 1179966) for the ICP Tempstar Heil RGS303HFAA0AAAA gas furnace. The electrode produces the high-voltage spark that lights the gas at the burner on every heat call. Repeated ignition cycles erode the electrode tip, crack the porcelain insulator, and let the spark gap drift, all of which lead to unreliable ignition. A worn electrode is a leading cause of a furnace that clicks but never lights, locks out on ignition failure, or short-cycles in cold weather. Installing a fresh OEM electrode restores a strong, consistent spark and dependable burner light-off.
