This OEM hot surface igniter/sensor (part #1009524, HSP kit) is the ignition source for ICP, Tempstar, and Heil gas furnaces. On a call for heat the control board energizes the igniter, which glows white-hot to ignite the gas at the burners; the same kit handles flame-proving so the board knows the burners lit. Silicon-nitride-style hot surface igniters are more durable than legacy silicon carbide elements but still wear out with thermal cycling. A failed igniter is the single most common no-heat cause: the inducer runs, the gas valve waits, but the burners never light and the furnace locks out.
