On a call for heat the control board sends voltage to the igniter, which heats to a glowing temperature and lights the burners. The igniter element is fragile and degrades with every heating cycle, eventually cracking or failing to reach ignition temperature. Including the wiring kit ensures a clean, fully-terminated connection — old igniter leads and connectors are a frequent failure point that causes intermittent no-heat calls. Replacing both together is the reliable fix for a furnace that clicks but won't light.\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 (Igniter)\u003c\/td\u003e\n\u003ctd\u003e1171306 — Ignitor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number (Wiring)\u003c\/td\u003e\n\u003ctd\u003e1188370 — Wiring Kit, Igniter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot surface igniter with wiring harness\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\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eBurner ignition source\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\u003eDesigned for the ICP RGS121LSAA0AAAA gas furnace and related platform units sold under ICP, Heil, Tempstar, and Comfortmaker that use this hot surface igniter and connector.
