This OEM hot surface igniter kit for the ICP RGS091LTCB0AAA gas furnace includes the igniter element (part number 1171306) and the matching igniter wiring kit (part number 1188370). On each call for heat, the furnace control board powers the igniter; it glows white-hot and lights the main burners. Hot surface igniters are brittle and degrade over thousands of heating cycles — the silicon carbide or nitride element develops hairline cracks and eventually fails open. A bad igniter is the leading cause of no-heat calls: the inducer runs and the gas valve tries to open, but the burners never light, so the furnace locks out. Replacing the igniter together with its wiring harness restores reliable ignition and eliminates intermittent, heat-stressed connections.
