This genuine OEM hot surface igniter (HSI, part number 1172533) is the ignition component for the ICP / Heil / Tempstar X9MPD075F12B2 gas furnace. The igniter glows red-hot on a call for heat to ignite the gas at the burners. This listing also covers the matched ignition-system parts for this model — the HSI flame sensor (1172543) that proves the burner flame, and the Honeywell VR8205-series snap-mount gas valve (1172541). A cracked or worn igniter is the single most common no-heat failure on these furnaces; the ceramic element becomes brittle with thermal cycling and eventually fails to glow or fractures.
