The electrode is positioned at the burner and, on each heat call, provides the precise gap and ceramic insulation needed to ignite the gas reliably. Over time the electrode tip can crack, erode, carbon-foul, or shift out of gap, leading to delayed ignition, repeated lockouts, or no heat at all. Because ignition components are exposed to direct flame and thermal cycling, they are a common wear item. Installing the exact OEM electrode restores correct gap geometry and dependable light-off, helping avoid nuisance lockouts and protecting the heat exchanger from unburned-gas events.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\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\u003eIgnitor Electrode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP \/ Heil \/ Tempstar \/ Comfortmaker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eGas Furnace Ignition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003eOEM Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eFactory replacement ignitor electrode for ICP \/ Tempstar \/ Heil model RGS303SFAA0AAAA and related ICP-family gas furnaces using this electrode.
