On a call for heat the control board energizes the igniter, it glows red-hot, and it lights the gas as the two-stage gas valve (compatible PN 1172822, Honeywell VR8205Q) opens. Hot surface igniters are brittle and degrade over time — a cracked, eroded, or open igniter is one of the most common causes of no-heat calls. Typical symptoms include the furnace running through its sequence but never lighting, an igniter that no longer glows, repeated ignition lockouts after several failed attempts, or a visibly cracked igniter element. Handle the new igniter only by its ceramic base — skin oils on the silicon carbide element can 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\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1172533\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter (HSI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTempstar (ICP \/ 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\u003eCompatible Gas Valve\u003c\/td\u003e\n\u003ctd\u003e1172822 (Honeywell VR8205Q, 2-stage)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003eOEM Replacement\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 T8MPV075F14C1 furnace and shared across many ICP-family furnaces sold under the Tempstar, Heil, Comfortmaker, and Arcoaire brands.
