On a call for heat the HSI glows white-hot to light the burner gas while the gas valve meters fuel to the manifold. Igniters are brittle and wear out with every cycle, and a stuck or failed gas valve will prevent ignition entirely. Typical symptoms include a furnace that tries to start but never lights, no glow from the igniter, ignition-failure lockouts, or no gas flow to the burners. Handle the igniter element only by its ceramic base — skin oils shorten its life.\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\u003eIgniter Part Number\u003c\/td\u003e\n\u003ctd\u003e1172533\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGas Valve Part Number\u003c\/td\u003e\n\u003ctd\u003e1175705 (Honeywell VR8205S)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter (HSI), Snap-Mount Gas Valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTempstar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e120V (igniter) \/ 24V (valve)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eDirect OEM fit for the Tempstar T8MPN100J20B2 gas furnace and related ICP\/Heil\/Tempstar\/Comfortmaker furnaces using the 1172533 hot surface igniter and the Honeywell VR8205S snap gas valve.
