Positioned at the burner, the electrode delivers the high-voltage spark that lights the gas at the start of every heating cycle and, on many designs, also serves as the sensing point that confirms a stable flame. Because it sits directly in the burner flame path, the electrode tip erodes, cracks, or develops a carbon\/oxide buildup over time, and the ceramic insulator can hairline-crack and short to ground. When it fails, the furnace clicks but won't light, ignites then locks out on a flame-sense fault, or short-cycles on repeated ignition attempts. Installing the correct OEM electrode restores a clean, reliable spark and proper gap geometry for dependable lighting.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1179966\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eSpark Igniter Electrode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP \/ Tempstar \/ Heil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eCeramic insulator, high-temp electrode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eOEM Direct Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eDirect-fit replacement for the ICP Tempstar Heil RGS300HDEA0AAAA and ICP-family furnaces built on the same chassis (Comfortmaker, Arcoaire, KeepRite, Day \u0026amp; Night).
