On a heat call, the ignition control sends high voltage to this electrode, generating a spark across its gap to light the gas at the burner. Unlike a hot surface igniter, a spark igniter does not glow — it arcs. As the electrode erodes or the porcelain insulator cracks, the spark weakens or shorts to ground, producing failed ignition, repeated lockouts, delayed light-off with a 'whoomp,' or no spark at all. This direct OEM replacement matches the original electrode geometry and gap so it lights the burner reliably without adjustment.\u003c\/p\u003e\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\u003e1184216\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eSpark Igniter \/ Sparker (Direct Spark Ignition)\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\u003eInsulator\u003c\/td\u003e\n\u003ctd\u003eCeramic \/ Porcelain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eGenerates ignition spark at the burner\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eFits the ICP\/Tempstar\/Heil RGS180LRAA0AAAA and related RGS-series gas units that call out part 1184216.
