When the thermostat calls for heat, the control board energizes the igniter to roughly 1,800–2,500°F so it can light the burner gas. The silicon carbide element is brittle and degrades with every heating cycle, making it one of the most common no-heat failure points. This listing ships with the matching OEM wiring kit (part #1188370) so the connector and harness are replaced together. Typical symptoms of a failed igniter include a furnace that cycles but never lights, a glowing element that cracks or no longer glows, and a unit that locks out after several ignition attempts.\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\u003eOEM Part Number\u003c\/td\u003e\n\u003ctd\u003e1171306 (igniter), 1188370 (wiring kit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter\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\u003eElement\u003c\/td\u003e\n\u003ctd\u003eSilicon Carbide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e120V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncludes\u003c\/td\u003e\n\u003ctd\u003eIgniter + OEM wiring kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eDirectly fits the ICP\/Tempstar\/Heil RGS121SEAA0AAAA gas furnace and shares the same igniter platform used across many RGS-series 80% furnaces.
