When the thermostat calls for heat and the gas valve opens, the igniter electrode generates the spark that lights the burner flame. The ceramic-insulated electrode and its precisely gapped tip are exposed to repeated thermal shock and corrosive combustion byproducts, so over time the tip erodes, the ceramic cracks, or carbon buildup prevents a reliable spark. A failing igniter is one of the most common no-heat causes: the furnace runs its ignition sequence, fails to light, and locks out. Installing a fresh OEM electrode restores fast, consistent first-try ignition and eliminates nuisance lockouts on cold mornings.\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\u003eIgniter Electrode (Ignition\/Spark)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP (Tempstar \/ Heil \/ Comfortmaker)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eCeramic-Insulated Electrode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\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\u003eBuilt for the ICP RGS243LTFA0AAAA and used across compatible ICP-family RGS-series gas furnaces marketed under Tempstar, Heil, Comfortmaker, and Arcoaire.
