The igniter generates the high-voltage spark that lights the burner gas at the start of each heating cycle. Over time the electrode tip erodes and the ceramic insulator cracks, leading to weak, intermittent, or no ignition. Common failure symptoms include a furnace that clicks repeatedly but never lights, delayed ignition with a noticeable 'whoomp,' lockout after several failed trials, or no spark at all. Replacing a worn igniter restores fast, reliable lightoff and prevents 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\u003e1184216\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eSpark Igniter \/ Sparker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP \/ Heil \/ Tempstar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIgnition Method\u003c\/td\u003e\n\u003ctd\u003eDirect Spark\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eOEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eFits the ICP\/Heil\/Tempstar RGS180HTAA0AAAA and shared-platform Comfortmaker furnaces using the same burner and ignition assembly.
