This OEM hot surface igniter (HSI) ignites the burners on your ICP/Heil/Tempstar RGS121LTBB0AAAA gas furnace. On a call for heat, the control board energizes the igniter, which glows white-hot and lights the burner gas. When an igniter cracks, develops hairline fractures, or burns out, the furnace will cycle on the inducer and gas valve but never establish a flame — leaving you with no heat and often a lockout fault code. This kit includes OEM igniter part 1171306 and igniter wiring kit 1188370 for a complete, plug-and-play replacement.
